Embodiment Construction

[0016] The content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] This embodiment is aimed at a certain river in Guangdong, located in the hinterland of the Pearl River Delta, with a total length of about 5,000 meters. With the development of industry and the rapid increase of population, the water quality of the river has become black and smelly. The river is along a long line, passing through industrial parks, residential areas, docks, food courts, etc., showing different pollution characteristics in different river sections. Generally speaking, due to certain industrial pollution in the area near the industrial park, the river bottom mud is seriously black and smelly; in the area near the residential area, domestic sewage is directly discharged into the river, and the organic pollution is serious, and there is oil on the river surface; there are farmlands along the river, which bring pesticide...

Abstract

The invention discloses a method for comprehensively treating river malodorous black. According to the method, aiming at formation reasons of the river malodorous black, on one hand, endogenous pollutants of a malodorous black river are reduced, and on the other hand, measures for ecological remediation are adopted to systemically repair a river ecological function, so that the malodorous black is eliminated, and stability and long effect are maintained. The technical scheme provided by the invention breaks a traditional controlling scheme that only one certain method is adopted for treating a river polluted water body or polluted bottom silt, adopts multiple technical schemes of pollutant reduction and ecological restoration, carries out technical combination according to circumstances such as river surrounding environment characteristics and hydrology situations, has the advantages of systematicness and long effect, achieves the aims of treating both symptoms and root causes and preventing the malodorous black from rebounding, and provides a feasible method for treating city malodorous black rivers.

Description

technical field [0001] The invention relates to the technical field of river comprehensive treatment, in particular to a method for comprehensive treatment of river black and odor. Background technique [0002] With the rapid economic development and population increase in our country, organic pollution is common in rivers and streams in many urban built-up areas, and the phenomenon of "black odor" is prominent, which has become an environmental problem that many cities and towns need to solve urgently. Although some small black and odorous rivers have achieved certain treatment effects, for longer black and odorous rivers, due to concentrated pollution, single treatment measures, unscientific, no long-term water quality maintenance mechanism, and no unified planning, the treatment effect is not good Well, even the phenomenon of water body returning to black appears, therefore, for the phenomenon of river black and odor, proposing a kind of long-acting comprehensive control ...
