Abstract

The invention discloses a method and device for treating and maintaining a black and odorous water body by inoculating with activated sludge, and belongs to the technical field of water environment control. According to the method and device for treating and maintaining the black and odorous water body by inoculating with the activated sludge, the black and odorous water body is treated synchronously by ''inoculating with the activated sludge and planting floating plants'', the amount of active microorganisms with degradability in the water body is increased, the removal effect of organic pollutants in the water body is improved and the nutrient pollution ammonia nitrogen concentration is reduced; and the device for treating and maintaining the black and odorous water body is a workboat which integrates the functions of activated sludge addition, sediment collection, ventilation and oxygenation, mixing of sludge and water, floating plant collection and transmission, compression and dehydration and the like, conducts in-situ control and remediation without destructive work on the water ecology, and has broad application prospects in the field of black and odorous water body control.

Description

technical field

[0001] The invention belongs to the technical field of black and odorous water environment treatment, and more specifically relates to a rapid and non-ecological damage in-situ treatment and maintenance method for black and odorous water. Background technique

[0002] The black and odorous urban water body loses its use function, which not only affects the landscape and daily life, but also brings harm to the health of residents. The "Water Pollution Prevention and Control Action Plan" officially issued by the State Council in April 2015 clearly stipulates that by 2020, the black and odorous water bodies in the built-up areas of cities at the prefecture level and above in my country will be controlled within 10%. Therefore, the treatment and restoration of black and odorous water bodies has become an urgent problem to be solved.

[0003] At present, the commonly used methods of black and odorous water restoration include chemical restoration, physical restor...
