High-efficiency black and odorous water treatment method and device

Abstract

The invention discloses a high-efficiency black and odorous water treatment method and device. The treatment device for purifying black and odorous water comprises an ecological floating island, wherein the ecological floating island comprises an ecological floating island rack and a plurality of planting tanks arranged on the ecological floating island rack; a self-driven displacement device is connected onto the ecological floating island rack and comprises a multi-parameter water quality detector, a first central processing unit and propellers which are respectively connected onto side periphery surfaces of the ecological floating island; the first central processing unit is used for receiving parameter signals of the multi-parameter water quality detector and presetting corresponding reference parameters; the propellers are arranged on the side periphery surfaces of the ecological floating island; an on-off controller of each propeller is controlled by the first central processingunit; and a self-generating device is connected onto the ecological floating island rack. A sludge treatment agent used for treating river sludge comprises 20-50 parts of modified charcoal powder, 30-50 parts of aggregate, 25-35 parts of a microbial agent, 15-25 parts of a co-substrate and 10-15 parts of an oxidizing agent.

Description

technical field [0001] The invention relates to a high-efficiency black and odorous water treatment method and device. Background technique [0002] Black odor is an extreme phenomenon of organic pollution in water bodies, which is caused by the lack of oxygen in water bodies and the corruption of organic matter. The direct cause of the black and odorous water body is the lack of DO dissolved oxygen, and the discharge of pollutants is the root cause of the black and odorous water body. The phenomenon of river black and odor is actually a biochemical phenomenon, which is the anaerobic decomposition of organic substances in water bodies. It is believed that the oxygen consumption of organic substances in the water body is greater than that of reoxygenation during the decomposition process, resulting in an anoxic environment, and anaerobic microorganisms decompose organic matter to produce a large amount of odorous gas that escapes from the water surface and enters the atmosph...
