With the continuous development of the economy, environmental pollution has become more and more serious, especially water pollution. During and after the “Eleventh Five-Year Plan”, China’s environmental protection and ecological construction and restoration work will be fully carried out. Among them, water pollution control, air pollution, solid waste pollution, heavy metal pollution, radioactive pollution control, and desertified land control are environmental protection and ecological, one of the very important contents of environmental construction. The purpose of this article is to study the application of lake and wetland ecological restoration technology in environmental pollution control and ecological restoration. Commonly used domestic lake pollution treatment methods include: microbial method, dredging and salvage, chemical sedimentation (flocculation), physical measures (filtration and membrane), constructed wetland, reoxygenation (micropores, turbulent aeration), mechanical dilution transfer (flushing) Water, water change) etc. The microbiological method is to put in microorganisms, the use of microbial preparations can digest and degrade organic pollutants and remove the purification mechanism of ammonia nitrogen and phosphorus, so as to achieve the goal of various water pollution control. And its disadvantage is that it can’t last forever. Ecosystem restoration project: It is the process of using engineering technology to assist the restoration of an ecosystem that has been degraded, destroyed, newly built or rebuilt. Its application enables the ecosystem to be restored and strengthened in terms of its own health, integrity and sustainability. Once the ecological restoration project is completed, the ecosystem does not need to be maintained by humans, as long as it is prevented from degrading due to disturbance. This is similar to the microbiological method in the lake and wetland ecological restoration technology.
