Problems solved by technology

[0005] ②Difficult to deal with: Different organic sewage has different components, usually organic sewage contains organic compounds such as halogens, hydrocarbons, oxygen, nitrogen, sulfur, phosphorus and heavy metal elements
In particular, high-concentration and toxic landfill leachate is not only costly to deal with, but also difficult to deal with, which is a difficult problem in sewage treatment in the world today.
[0006] ③Great hazards: high-concentration and foul-smelling landfill leachate is a kind of toxic sewage, and its odor will have toxic and side effects on human breathing, digestion, and vascular nervous system
Its treatment has high treatment cost, immature treatment process and low compliance rate, which poses a great threat to the environment

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the embodiments. The description in this part is only exemplary and explanatory, and should not have any limitation on the protection scope of the present invention.

[0013] A biological dilution technology of organic sewage, including the following operation process: will use COD (chemical oxygen demand), BOD (biochemical oxygen demand) high concentration of organic sewage and COD, BOD low concentration of urban organic sewage Adjusted to COD7000mg / L, BOD 8000mg / L, mixed with Shewanella putrefaction.

[0014] The higher or lower concentration content is relative to COD7000mg / L and BOD8000mg / L.

[0015] Shewanella putrefaction, with Shewanella high-efficiency azo reduction. Three representative species of Shewanella were the research objects, and the influence of humus on azo reduction under anaerobic conditions was studied. The experimental results show that the three representative strains have ef...

Abstract

The invention discloses a biological dilution technique for organic sewage. The organic sewage with a higher chemical oxygen consumption concentration content and a higher biochemical oxygen demand concentration content and city organic sewage with a higher chemical oxygen consumption concentration content and a lower biochemical oxygen demand concentration content are mixed and uniformly stirred so that the chemical oxygen consumption of mixed organic sewage is 7000ml/L and the biochemical oxygen demand is 8000ml/L, and shewanella putrefaciens is added for culture. Through the adoption of the biological dilution technique disclosed by the invention, the chemical oxygen consumption concentration content and the biochemical oxygen demand concentration content in the organic sewage can be effectively reduced, and the shewanella putrefaciens is used for deep reduction, so that the operation is simple and convenient, and the effect is good.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological dilution technology of organic sewage. Background technique [0002] With the continuous development of society and economy, countries around the world are paying more and more attention to the development of environmentally friendly materials, renewable clean new energy, development of recycling, low-carbon economy and conservation and emission reduction. In recent years, my country has successively promulgated a series of policies, regulations and measures such as the "Renewable Energy Law of the People's Republic of China", the "Law of the People's Republic of China on Promoting the Transformation of Scientific and Technological Achievements", and the "Law of the People's Republic of Research and develop new technologies to solve my country's current outstanding environmental protection and energy shortage problems. [0003] Organic sewage such as urban garbage ...
