Microbial activation system and preparation method of microbial activation filler

Abstract

The invention relates to the technical field of ecological restoration, and discloses a microbial activation system and a preparation method of a microbial activation filler, the microbial activation system comprises a black, odorous and eutrophicated water reservoir, the outer wall of the black, odorous and eutrophicated water reservoir is connected with a water delivery pipe, and the outer wall of the water delivery pipe is connected with a water pump; the black, odorous and eutrophic water reservoir is connected with a self-priming pump through a water conveying pipe, a water inlet control valve is mounted at the output end of the self-priming pump, and the output end of the self-priming pump is connected with a purification reaction tank through a water conveying pipe. According to the microbial activation system and the preparation method of the microbial activation filler, the number of native microorganisms and specific microorganisms in a water body is activated to increase in geometric progression, and the water body is used for replacing a traditional limited bioreactor, so that the growth space of the microorganisms is greatly released, and the effects on pollutants in the water body in the mass propagation process of the microorganisms are fully exerted; and material flow transfer of pollutants among different nutrition levels of a water body ecosystem is realized.

Description

technical field [0001] The invention relates to a microbial activation system and a preparation method of a microbial activation filling material, belonging to the technical field of ecological restoration. Background technique [0002] Eutrophic water body refers to the enrichment of nitrogen and phosphorus nutrients in the water body, which causes algae and other plankton to multiply rapidly, and the dissolved oxygen in the water body decreases, causing water pollution. Such water body is called eutrophic water body. Eutrophication of water body is mainly caused by excessive content of nutrients such as nitrogen and phosphorus, among which phosphorus is one of the most critical factors leading to eutrophication of water body. Controlling the phosphorus content in water is a key part of solving the problem of eutrophication in water. The root cause of the black and odorous water body is that the speed of decomposition of ammonia nitrogen compounds and organic matter by rel...

Problems solved by technology

However, when a large amount of chemical agents are added to control the black, odorous and eutrophic water bodies of the river, it will also cause secondary pollution to the water bodies, and the operating costs are extremely high. Usually, it is only used as an emergency measure to deal with sudden water body pollution.

[0005] The traditional biological water treatment process can effectively remove carbon, nitrogen, and phosphorus in wastewater, but its biological removal mechanism is completed in a closed microbial action unit, and the removal of phosphorus is mainly due to the discharge of sludge, and a large amount of sludge The production not only causes secondary pollution, but also has extremely high investment and operating costs. The traditional biological treatment process represented by the activated sludge method is difficult to apply to the restoration of river courses and landscape water bodies.
