Abstract

The invention belongs to the technical field of sewage purification, and particularly discloses an in-situ ecological ditch pollution interception and purification method for a water supplementing system. The method comprises the following steps: (1) salvaging sludge at the bottom of a river channel, screening, separating and culturing indigenous microorganisms, domesticating, and re-feeding the domesticated indigenous microorganisms into the river channel; (2) reconstructing the river channel into an ecological ditch, and successively dividing the ecological ditch into a microorganism restoration area, an aeration area, a denitrification area and a plant absorption area; (3) arranging an aeration filter apparatus in the aeration area, and enabling the aeration filter apparatus to run continuously for 6 to 10 hours; cleaning up impurities isolated in the aeration area every 25 to 40 days; and (4) purifying the water in the ecological ditch by virtue of the microorganism restoration area, the aeration area, the denitrification area and the plant absorption area to finally flow into the secondary rivers and lakes. By using the method of the invention, the sewage is purified in situ in the water supplementing system, so that the water flowing into the secondary rivers and lakes is ensured to be clean, and no secondary pollution is caused.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, and in particular relates to an in-situ ecological ditch pollution interception and purification method of a replenishment water system. Background technique [0002] With the continuous acceleration of urbanization and the rapid increase of urban population, the contradiction between urban environmental pollution and economic development has become increasingly prominent, and water pollution has become a public hazard for sustainable urban development. Sources of water pollution can be divided into two categories: point source pollution and non-point source pollution. Point source pollution caused by large and medium-sized enterprises falls within the scope of internal governance of the enterprise; while urban domestic sewage, a small amount of sewage discharged by small enterprises, and agricultural The non-point source pollution caused by fertilization and pesticide use has a wide ...
