Problems solved by technology

[0014] (4) Thermal pollution of water body
[0022] 1. The disadvantage of direct aeration by aeration pump is that it consumes a lot of energy, and in the early stage of aeration, there will be a lot of odor emitted, which will affect the normal life of surrounding residents. Citizens have great opinions
Continuous aeration is required 24 hours a day, and the cost of electricity is high
[0023] 2. To increase water replenishment upstream, the disadvantage is that when the river ebbs, the replenished water will flow away
[0025] 4. Planting aquatic plants in the river will affect the original function of the river, and it is easy to breed mosquitoes, and the plants themselves will rot after death and cause secondary pollution.
[0026] 5. Microbial technology can reduce the black and odor of rivers, but it does not last long
There are also many problems with the use of microbial agents, such as dealing with eutrophication, and the removal of phosphorus by microorganisms is very complicated, and cannot be removed in river courses; nitrogen removal is also difficult

Abstract

The invention discloses a mixed strain capable of continuously degrading sulfides in black and odorous river water, a strain carrier and a method. The mixed strain is prepared from bacillus subtilis,bacillus licheniformis, EM bacteria, photosynthetic bacteria, bacillus natto, bacillus laterosporus and bacillus megatherium. All microorganisms in the mixed strain are domesticated into botanical microorganisms, and short-chain fatty acids are mixed in the mixed strain. By synergistic effects of various means, effective treatment is performed aiming at the sulfides in the black and odorous riverwater.

Description

technical field [0001] The invention relates to the technical field of river black and odorous water treatment, in particular to a mixed strain, a strain carrier and a method for sustainably degrading sulfide in river black and odorous water. 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 matter in the water body is greater than that of reoxygenation during the decomposition process, resulting in an anoxic environment, and anaerobic microorganisms deco...
