Abstract

The invention discloses an urban and rural surface ditch transformation method with an intercepting function and an intercepting and purifying assembly. The transformation method comprises the steps that an original ditch is trimmed and reinforced, a channel is prefabricated according to the original ditch, then the prefabricated channel is installed in the ditch and reinforced, finally ecological plants are planted in the channel, and pollutants in the sewage are converted and absorbed by utilizing ecological plants, so that the sewage interception and purification effects are realized. The intercepting and purifying assembly comprises an intercepting box, collecting boxes, a purifying assembly and a cleaning assembly; a water passing hole is formed in the intercepting box, the collecting boxes are arranged on the two sides of the intercepting box, the purifying assembly is arranged in the intercepting box, the cleaning assembly comprises a cleaning motor and a movable scraper, the cleaning motor is arranged on the intercepting box, the movable scraper is clamped to the intercepting box, and the cleaning motor provides power for the movable scraper. The method can effectively improve the urban and rural ecological environment and promote the development of urban and rural economy, and is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reconstruction method for urban and rural surface ditches with an interception function and an interception and purification component. Background technique [0002] With the increase of urban population and the continuous improvement of urban and rural people's living standards, 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 Non-point source pollution caused by fertilizat...
