Problems solved by technology

These conventional methods are comprehensively treated through aeration, anaerobic, aerobic, electrolysis, membrane filtration and other processes. Not only the treatment results are difficult to meet the national emission standards, but also the operating costs are very high
[0006] The currently used better process is a compound process based on physical and chemical precipitation, supplemented by biochemical treatment, and advanced membrane treatment. It has large investment, large area, high energy consumption, high operating cost, difficult daily maintenance, and difficult to meet the discharge water standard stably.

Embodiment 1

[0051] The process of cultivating complex microorganisms is as follows: add 25-40 kg of brown sugar (syrup) to 1 ton of water and mix for 24 hours. Stir and ferment for 24 hours, then add 5,000ml of lactic acid bacteria, bifidobacteria, spores and DL bacteria, stir and ferment for 24 hours, measure the pH value of about 4.0, get the finished product, and store it.

[0052] The beneficial microbial flora with special pollution control effects, that is, the above-mentioned composite microorganisms are domesticated in domestication places, and then added to anaerobic reaction equipment, microbial reaction equipment, microbial fluidization equipment and ecological tank equipment to treat landfill leachate. Various pollutants are rapidly enriched and degraded, heavy metal ions are converted into non-toxic, harmless and stable substances, and some organic pollutants are degraded into CO 2 、H 2 O, CH 4 , the preferred daily processing capacity of the present embodiment is 10 tons. ...

Abstract

The invention discloses a method and application for using compound microorganisms for landfill leachate treatment. The method is achieved by treating landfill leachate through compound organisms. The compound organisms are compounds containing photosynthetic bacteria and florae, saccharomycetes and florae, actinomycetes and florae, nitrogen-fixing bacteria and florae, lactic acid bacteria and florae, bifidobacteria and florae, spore bacteria and florae, and DL bacteria and florae. Applied treatment devices include an anaerobic reaction device, a decoloration and sedimentation device, a treatment unit and a microorganism fluidization device which are sequentially connected. The treatment unit comprises a microorganism reaction device and a dense sedimentation device arranged behind the microorganism reaction device. The anaerobic reaction device, the microorganism reaction device and the microorganism fluidization device are filled with compound microorganisms. By means of the method and application for using compound microorganisms for landfill leachate treatment, the effects of sludge removal and zero emission can be achieved, and discharged water is free of odor and corrosion, colorless and tasteless, and various physicochemical indexes reach national standards.

Description

technical field [0001] The invention relates to a method and application of microorganisms for treating sewage, in particular to a method and application of composite microorganisms for treating landfill leachate. Background technique [0002] Nature is a three-dimensional space composed of plants, animals, and microorganisms. Microorganisms are widely distributed in nature and various organisms. They play an important role in the material cycle of nature (absorption, decomposition, enrichment, transformation), and can control the development of nature in two directions: regeneration and corruption. [0003] Microbial technology is based on microorganisms that appear in the biological world, and is formed with the help of artificial process engineering. Microbial sewage treatment technology is to combine the components of various sewage, organically cultivate a variety of microorganisms together, and metabolize a variety of enzymes while coexisting and co-existing to form a...
