River channel pollution-intercepting ad purifying system and method

Abstract

The invention discloses a river channel pollution-intercepting ad purifying system and method, involving a sewage isolating device and a sewage purifying system. The sewage isolating device comprisesfloaters, enclosure skirting, pile tie ropes and footing piles. The sewage isolating device is arranged along the two sides of a river bank; the enclosure skirting, the river bank and a river bed forman enclosed isolating zone; the floaters that float on water are connected to the top of the enclosure skirting; the bottom of the enclosure skirting is fixed to the river bed via the pile tie ropesand the footing piles; the sewage purifying system is disposed in the isolating zone and comprises a plant purifying unit, a hollow fiber composite biological unit and a porous nanofiller unit. The floaters, the watertight skirting and the footing piles are arranged on the two sides of a river channel to gather all river sewage in the isolating zone when there is no need for draining river water;the plant purifying unit, the hollow fiber composite biological unit and the porous nanofiller unit help treat the sewage; therefore, the pollution intercepting effect is good, lasts long and is stable.

Description

Technical field: [0001] The invention belongs to the technical field of sewage treatment and ecological restoration, and specifically relates to a river channel sewage interception and purification system and method. Background technique: [0002] The water environment quality of my country's rivers has declined sharply in the past 20 years. The water quality of most rivers is inferior to Class V. The problems of water pollution and ecological degradation are very prominent. The content of reducing organic matter and nitrogen and phosphorus nutrients remains high, and even perennial water bodies Black and smelly phenomenon. This not only hinders the sustainable development of economy and society, but also seriously affects the health and life of coastal residents. Eliminating the black and odorous phenomenon of the river and restoring the ecological function of the river has become one of the key tasks in the process of social sustainable development. [0003] However, most...

Problems solved by technology

[0003] However, most of the current patented technologies for river treatment focus on in-situ purification and restoration, and there are few technologies for diversion, interception and disposal of exogenous pollutants.
