Introduction: with the development of social economy, the rapid development of the continuous improvement of living standards and the real estate industry, people's demand on living environment and taste is increasing, city parks and residential district design more and more emphasis on natural, ecological green space, more and more people desire a hydrophilic landscape, to improve the micro climate of the city &ldquo &rdquo, alleviate the city; stone forest; crowded feeling, return to nature. Therefore, the use of suburban production ponds and excavation of artificial lake green space construction project is more and more included in the construction of residential areas or parks.  
1. landscape water pollution cause  
The water pollution of urban landscape water mainly includes the following four reasons: first, the landscape water province belongs to stagnant water. Such water bodies lack mobility, poor oxygen recovery ability, weak biological oxidation capacity, resulting in poor water purification capacity; two, pollution caused by external factors. For example, garbage, debris, dust, leaves, as well as rainwater or other wastewater into the pollutants. These substances dissolved in water, precipitation and decay, resulting in water quality deterioration; three is the lack of water, landscape water purification chain. The chain system of water environment can play a role in water purification, but most of the landscape water lack of food chain system complete; four, the landscape water pollution situation appears endogenous. The so-called endogenous pollution is the substance that is integrated into the water and does not have the ability to pollute the water environment. However, after a period of time, chemical reactions may occur in the water, forming water pollution substances and destroying the water quality.  
2. ecological water treatment technology and method  
Ecological water treatment technology is the way and way to remove harmful substances in water, regulate water quality and improve water ecological environment through physical and chemical means. At present, in addition to the traditional methods of pollution source control, physical and chemical treatment, aquatic biological treatment, aeration and oxygen treatment, the ecological treatment technology has successfully developed microbial treatment, adding photosynthetic bacteria and other processing methods with the continuous improvement of science and technology.  
2.1 pollution sources control  
Control pollution source is to put an end to domestic sewage, waste water into the landscape water, and timely removal of floating objects on the water surface.  
2.2 physical chemical treatment of  
According to the physical and chemical principles, the harmful substances and impurities in the landscape water are analyzed, so that the water quality is guaranteed to be clean, and the self purification ability is gradually restored. For example, by mechanical filtration, regular replenishment, dosing sterilization, algae and other methods Jiasha investment agent. In this way, most of the chemical substances need to be put into the landscape water, which can cause two pollution. Therefore, in general, the water ecological treatment technology is only applied to the fountain area with smaller water body.  
2.3 treatment of   with aquatic organisms;
This is the main way of using food chain ecosystem uptake and biological allelopathy principle, to improve water quality and restore the ecological balance of the population structure change by water. Here, aquatic plants mainly refer to zooplankton, swimming animals and zoobenthos. These aquatic animals feed on free bacteria, planktonic algae and organic detritus in water bodies, which can effectively reduce suspended solids in water and improve the cleanliness of water bodies. For example, the use of large aquatic plants to absorb nutrients to control eutrophication occurs.  
2.4 aeration aeration treatment  
As the name suggests, aeration is the way to supplement oxygen to the water, to ensure that aquatic life activities and microbial oxidation decomposition of organic matter with enough oxygen, in order to achieve the purpose of water purification. Aeration method mainly includes natural drop aeration and mechanical aeration. Although natural dropping aeration oxygenation efficiency is low, but because it has no energy consumption, simple maintenance, so it has been widely used in landscape water treatment principle.  
2.5 microbial treatment of  
Microbial treatment method is an efficient and advanced landscape water ecological treatment technology in china. Simply who, it is the use of microbial activities of life, the wastewater dissolved and colloidal state of organic pollutants degradation, so as to purify the role of water.  
2.6 photosynthetic bacteria  
Because photosynthetic bacteria can utilize light energy and oxygen to convert inorganic and organic carbon sources and other nutrients in micro polluted water or wastewater into bacteria, the treatment method of photosynthetic bacteria can also purify water quality. This kind of landscape water treatment method has the advantages of simple process, no construction, and other advantages, in addition to widely used in China, in Japan, South Korea and other countries are also widely used.  
ThreeEcological purification of lake water for artificial lake  
Wetland ecosystem is the interaction of land and water with the atmosphere, mutual influence and mutual penetration. It is a special ecosystem with dual characteristics of land and water. The wetland ecosystem connects the terrestrial ecosystem with the aquatic ecosystem through the material cycle, energy flow and information transmission. It is the product of the balance between the three land, water and atmosphere in nature. The unique habitat of wetland makes it rich in terrestrial and aquatic animal and plant resources. It is the most abundant and productive natural ecosystem in the world. Wetland has other ecosystems in the runoff regulation, maintaining biodiversity, flood and drought, pollution control and other aspects of the irreplaceable role.  
The lake itself is a wetland ecosystem, has certain self purification function, the construction of ecological artificial lake lake usually take its circulation, self purification method, through the construction simulation of natural wetland ecosystem, the formation of artificial lake ecological green lake water treatment system, to achieve the automatic, natural to maintain good water quality. The ecological lake green space system is a specially constructed green space system, which makes it suitable for plant growth and microbial activities (including aerobic and anaerobic processes). It uses the interaction between the matrix, plant and microorganism in the module, and achieves the purification treatment of the lake by the three functions of physical, chemical and biological in the natural ecosystem.  
The ecological lake green land treatment system is designed on the basis of the general green space, which is constructed by artificial construction and supervised by the ecological module with a certain aspect ratio. The main module for a packed bed composed of gravel, sand, sand, microorganisms, and the bed body surface treatment planting has good performance, good tolerance, strong adaptability, developed roots and beautiful plants.  
The nutrients in lake water are degraded by microorganisms and absorbed by plants. The plants absorb nutrients from the lake water through photosynthesis and effectively remove ammonia, nitrogen, phosphorus and other compounds in the lake water. At the same time, plants are constantly using solar energy for photosynthesis, providing oxygen sources for microbial oxidation reactions.  
On the one hand, the lake water can flow through the filling gap of the bed and filter and oxygenation to achieve the aerobic treatment of microorganisms. On the other hand, it can make full use of the biofilm on the surface of the packing, the root system of the developed plant and the interception of the surface soil and the filler, so as to further improve the processing capacity and treatment effect. The aquatic plants, water and microbial plankton, various animal lake, such as fish, shrimp, soft animal, form a relatively stable food chain and ecosystem, to achieve the natural ecological lake effect. In addition, but also through the lake surrounding the artificial waterfall or fountain device, enhanced water circulation flow of the lake, the lake to increase the oxygen content, enhance the material exchange and circulation of all kinds of The new supersedes the old. water activity and activity and water, fresh and keep water view; through the municipal pipe network system and water treatment system (simple conditional then, the lake surrounding the building), green space and road rainwater collected together to the lake, because the bottom structure is soft, natural groundwater may also penetrate into the lake, in the lake surrounding the appropriate construction machinery to ground water pumping device, which can solve the problem of the lake water basically. At the same time, but also can be used as a green water lake water, plants absorb again after the return water; water quantity and water quality by periodically sampling inspection statistics of lake, determine the variety and quantity of lake fish shrimp animal and aquatic plants, the ecological system of the state to maintain balance, so as to ensure the ecological effect and ecological lake the landscape effect, but also reduce the maintenance of property management costs, will reduce the cost of living of the owners.  
4. conclusion  
To sum up, how to treat the resources, treat the environment, rational use of land resources, including wetland pond, the ecological landscape, through the processing method, construction scale, layout of the appropriate artificial lake space, to improve the residential park or garden environment and micro climate, improve people's living environment quality and style, is a we should constantly sum up the landscape designer and study.
