Embodiment Construction

[0013] After the bacteria are fermented in liquid, add 40 mesh zeolite powder or porous ceramsite to attach and cultivate for 48 hours to solidify. Dehydrate and dry after detecting the number of live bacteria > 200 million / g. To clean up the sewage, use it according to the water quality and treatment capacity, and use 10 kg of powdered bacterial agent for 5000M3 water inferior to Class V. When the water flow rate is >0.5M / S, the granular bacterial agent should be applied.

Abstract

The invention discloses a compound microorganism bacterium agent sewage cleaning technology which belongs to the technical field of bioengineering. A great amount of contaminants are discharged into water bodies due to human activities, and as a result, the physical and chemical properties or biocoenosis compositions of the water bodies are changed, so that the use values of the water bodies are decreased. The severe consequence of water body pollution affects not only the health of human being but also industrial and agricultural production. According to the technology, efficient flocculation strain jelly bcereus, bacillus subtilis, aerobic bacillus licheniformis and nitrophilous actinomycete micromonospora are screened and adopted to prepare a compound microorganism bacterium agent (special for sewage). The compound microorganism bacterium agent has the advantages of small usage amount, high flocculation force, quick organic matter decomposition, no antagonism, good aerobic performance, no odor, no secondary pollution, pollution decomposition rate higher than pollution rate, high adaptability and viability, low cost and industrial production availability.

Description

technical field [0001] "A Composite Microbial Agent Cleans Up Sewage Technology" belongs to the field of bioengineering technology. Microbiology, molecular biology, biochemistry and cytology involved in biology, water treatment biology, environmental microbiology and water quality engineering; combined with modern engineering technologies such as chemical engineering and machinery. Background technique [0002] In environmental science, the water body includes not only the water itself, but also suspended matter, dissolved matter, colloidal matter, bottom (mud) and aquatic organisms in the water. It is a complete ecosystem, which can be divided into terrestrial water bodies, marine water bodies, surface water bodies and groundwater bodies, etc. Due to human activities, a large amount of pollutants are discharged into the water body, which changes the physical and chemical properties of the water body or the composition of the biological community, thereby reducing the use v...
