River course pollution remediation treatment technology

Abstract

The invention discloses a river course pollution remediation treatment technology, relates to the field of river course treatment, and solves the problem that river course pollution cannot be fundamentally eliminated in a prior treatment method. The technology comprises the steps that one, a sewage discharging pipe is arranged in a river course; two, cut-off dikes are arranged at the two ends of the river course, and river water within the cut-off dikes is pumped to the downstream of the river course; three, microorganisms in sludge at the bottom of the river course are analyzed to obtain beneficial bacteria, and the beneficial bacteria are directionally proliferated to clear the sludge at the bottom of the river course; four, cleaned and clear river water is introduced into the river course, and the beneficial bacteria, aquatic creatures and a water quality regulating agent are put into the river course; five, the cut-off dikes are removed, and river water flows again. The technologyhas the advantages that the sewage discharging pipe is arranged in the river course, and the two ends of the sewage discharging pipe are directly communicated with a sewage discharging port and a sewage treatment plant to eliminate a sewage source of the river course and greatly reduce the source of the pollution; a manner in which the river course is treated by completely draining water is adopted, and the downstream of the river course can be effectively prevented from being affected by pollutants.

Description

technical field [0001] The invention relates to the field of river channel management, in particular to a river channel pollution restoration and control process. Background technique [0002] Our country has a vast territory and many rivers, resulting in many river courses. River courses are the routes through which rivers flow, usually referring to navigable waterways. However, with the acceleration of urbanization, the amount of sewage discharge has increased significantly, and a large amount of sewage and domestic waste are directly discharged into the river. Coupled with rainfall, the runoff, sediment and sewage produced on the surface re-enter the river circulation system, resulting in river pollution. The situation is serious, damaging river biological resources, damaging river water and river environmental quality, and endangering human health. [0003] People try every means to control the pollution of river channels. The existing methods mostly use dosing of drugs...

However, with the acceleration of urbanization, the amount of sewage discharge has increased significantly, and a large amount of sewage and domestic waste are directly discharged into the river. Coupled with rainfall, the runoff, sediment and sewage produced on the surface re-enter the river circulation system, resulting in river pollution. The situation is serious, damaging the biological resources of the river, damaging the quality of the river water and the river environment, and endangering human health

[0003] People try every means to control the pollution of river channels. The existing methods mostly use dosing of drugs, diversion of water for flushing, and sediment dredging. Pollutants that have been deposited on the bottom of the river are agitated, causing pollution to spread and destroying the water environment. Most of the drugs used are chemical agents, which are likely to cause secondary pollution. Water flushing is to transfer the pollution to other water bodies, causing a wider range of pollution , none of the above methods can fundamentally eliminate river pollution
