Abstract

The invention discloses a black and odorous water body treating device and a use method thereof. The treating device is formed by the following parts: (1) a coagulating sedimentation or gas floating system; (2) an electrolysis system; (3) a sludge treating system. A black and odorous water body is divided into water bodies one section by one section by rubber dams, then a lifting pump is utilizedto take water from downstream of the black and odorous water body, a water outlet of the lifting pump is connected with a water inlet of the coagulating sedimentation system or the gas floating system, a water outlet of the coagulating sedimentation system or the gas floating system is connected with a water inlet of the electrolysis system, and a water outlet of the electrolysis system is drainedinto upstream of the black and the odorous water body to be circulated; a sludge discharging opening of the coagulating sedimentation system or the gas floating system is connected with an inlet of the sludge treating system to enter a sludge dewatering machine, and the sludge is dewatered by a dewatering machine of the sludge treating system into mud blocks and press filtrate. SS, COD, BOD, ammonia nitrogen, total nitrogen, total phosphorus and chromaticity are removed by coagulation and electrolysis, so that dissolved oxygen depth is improved, and the black and odorous water body can be treated.

Description

technical field [0001] The invention belongs to the field of water pollution control of environmental engineering, and more specifically relates to a treatment device for black and odorous water and a method for using the same. Background technique [0002] Black and odorous water refers to blackening and smelling due to excessive pollution and exceeding its water environment capacity. It is usually lower than the surface water environmental quality standard V water quality standard, and the dissolved oxygen is less than 2.0mg / L. Most of them are located in areas with dense population, high pollution load intensity, and imperfect infrastructure, mainly including water bodies in urban built-up areas, urban-rural fringe areas, county towns, and central towns. Causes of black and odorous water bodies: (1) Exogenous organic matter and ammonia nitrogen consume oxygen in water: when the dissolved oxygen drops to a low level, a large amount of organic matter is further decomposed u...
