Study on Ecological Remediation Method of Purification of Rural Polluted Slow-Flow Water

摘要

Slow-flow water is the main part of rural water, human activities to the semi-enclosed water caused serious pollution. Water bio-ecological remediation method can increase the ecosystem diversity, self purification capacity and system stability. The technology includes adding microorganisms, constructed wetlands, ecological revetment, biological manipulation, remediation of aquatic vegetation, artificial aeration. The ecological remediation technology practice of moist areas in southern China by pollution slow-flow water including: ecological floating island, anaerobic + artificial wetland, underground integrated equipment + ecological floating island, grit chamber + AO + artificial wetland + oxidation pond, constructed wetlands + oxidation pond, anaerobic oxidation + oxidation pond, highly efficient and stable pond. The engineering practices show that the ecological remediation method can effectively purify the pollution of slow-flow water.
