Method for governing pollution of river surge

Abstract

This invention provides a combined method for treating urban river surge with bioremediation as the major technique. The method comprises: pre-treating polluted water body of upstream urban river surge in an oxidation pool, performing biological oxidative remediation on bottom deposits in river, aerating river channel, performing bioremediation on middle reach water body, and performing ecological remediation on downstream water body. The method utilizes abandoned fishpond, vacant land or modified oxidation pool to perform pre-treatment on heavily polluted water body of urban river surge that cannot be treated by sewage interception. Then the method adopts biological oxidative remediation on bottom deposits to control internal pollution source of urban river surge, and artificial aeration, and biological-ecological remediation to effectively eliminate pollutants and odor of water body, improve water quality of urban river surge, and improve self-cleaning ability of urban river surge water body. The method is a feasible method in treating urban river surge.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for comprehensive treatment of river gushing pollution, which focuses on bioremediation technology and integrates multiple treatment technologies. technical background [0002] Black and smelly rivers are a common phenomenon in the urban river network in our country. The treatment of black and smelly rivers in cities in my country mainly adopts municipal engineering methods such as sewage interception, revetment, and dredging. However, for most of the black and smelly rivers in the suburbs, due to lack of funds and lack of uniformity Due to planning and other reasons, pollution cannot be intercepted or cannot be intercepted in the near future. Therefore, there is currently no ideal method for controlling river gush pollution. After inquiring about Chinese patent information, no prior application for bioremediation treatment methods using integrate...

Problems solved by technology

[0002] Black and odorous rivers are a common phenomenon in urban river networks in my country. The treatment of urban black and odorous rivers in my country mainly uses municipal engineering methods such as sewage interception, bank revetment, and dredging. However, for most suburban black and odorous rivers, due to lack of funds and no unified Due to planning and other reasons, sewage interception cannot be carried out or cannot be intercepted in the near future

Therefore, there is no ideal river pollution control method at present.

After inquiring about Chinese patent information, no prior application for bioremediation treatment using integrated multiple treatment technologies was found.
