Method of Utilizing Microorganisms to Treat Black Odor Anaerobic Sludge

Abstract

The invention discloses a method for using microorganisms to treat anaerobic black and odorous sludge, comprising: S1, pulverizing rice bran and straw into powder, mixing and stirring evenly to obtain a raw material mixture; S2, soaking the raw material mixture with a low-temperature domesticated microbial water agent ; S3. Stir and mix the soaked raw material mixture with the sludge to be purified, then add a catalytic enzyme biocomposting agent, fully mix, expose to the air and let stand to purify the sludge to obtain purified soil. The present invention utilizes microorganisms to rapidly decompose pollutants in the organic river course (sludge), and quickly reduces the content of organic matter such as ammonia, nitrogen, phosphorus and potassium in the sludge through decomposition, absorption, and transfer, so that it can be volatilized in a gaseous state and form an inorganic matter with a content of The main soil composition, so as to achieve the best treatment effect, will not produce secondary pollution, achieve the purpose of treating the symptoms and the root cause, and directly catalyze the decomposition on site, avoiding long-distance transportation, with safety, high efficiency, low cost, low investment, simple operation, etc. advantage.

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...

AI Technical Summary

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
