Method for treating black odorous anaerobic sludge by utilizing microorganisms

Abstract

The invention discloses a method for treating black odorous anaerobic sludge by utilizing microorganisms. The method comprises the following steps: S1, crushing rice chaff and straws into powder, andcarrying out uniform mixing and stirring to obtain a raw material mixture; S2, soaking the raw material mixture with a water aqua of low-temperature domesticated microbes; and S3, subjecting the soaked raw material mixture and sludge to be purified to stirring and mixing, then adding a catalytic enzyme biological composting agent, carrying out full mixing, exposing the obtained mixture to air, andconducting standing to purify the sludge so as to obtain purified soil. According to the method, pollutants in an organic river (sludge) are rapidly decomposed by utilizing the microbe, and the contents of organic matters such as ammonia, nitrogen, phosphorus and potassium in the sludge are rapidly reduced through decomposition, absorption and transfer, so the organic matters are volatilized in agaseous form, and soil components mainly containing inorganic matters are formed; and therefore, optimal treatment effect is achieved, no secondary pollution is generated, and the aims of treating both symptoms and root causes are achieved. Moreover, on-site direct catalytic decomposition is realized, so long-distance transportation is avoided, and the method has the advantages of safety, high efficiency, low cost, reduced investment, simplicity in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of water area ecological treatment, and in particular relates to a method for treating black and odorous anaerobic sludge by using microorganisms. Background technique [0002] With the rapid development of social economy and the acceleration of urbanization, the evolution of the water environment is greatly disturbed by human activities, and the contradiction between the normal maintenance of the water ecosystem and human activities is very prominent. Over the years, due to the huge amount of water used in industry and agriculture in my country, the cumulative effect of water pollutant discharge on water bodies is obvious. For flood control, sewage interception, and water resource utilization, a large number of rivers, lakes and reservoirs have been cut and straightened, and the bottom has been hardened. , cut-off water intake and other projects, the self-purification and self-repair capabilities of water bo...

Problems solved by technology

The existing water purification function is single. After purifying the water quality, it is easy to cause harmful substances to remain in the water, the bottom sludge is difficult to purify, and the harmful microorganisms in the water body reproduce in large numbers, which does not really play a role in purifying the water quality.

The existing treatment methods are generally physical, chemical and biological methods, but the physical method has high investment cost and slow effect, and the chemical method has the problem of high use cost and easy to cause secondary pollution of the water body. Biological methods are used in the treatment of black and odorous rivers. The application is very extensive, mainly including artificial wetland treatment, aquatic plant restoration, bioremediation, etc., but the biological method has the problem of slow processing speed
