Embodiment Construction

[0026] First, the extraction process of the strains is described:

[0027] Take the mixture of 30% bacterial liquid, 60% medium and 10% waste liquid as the starting point of acclimatization, cultivate for about 40 hours to reach the logarithmic growth phase, then take 50% of it, and supplement the same volume with 2 / 5 waste water , the mixture of 3 / 5 medium was cultured for 40 hours, then mixed with 3 / 5 waste water and 2 / 5 medium to repeat the above process, and gradually increased the content of waste water and reduced the amount of medium in the same way until the waste water was completely used until. When the proportion of wastewater gradually increases, the time for each cultivation and domestication should be extended accordingly to ensure the growth advantage and concentration of photosynthetic bacteria, and the domestication conditions are the same as above. When it is completely domesticated with waste water and repeated 3-4 times, it is a domesticated strain.

Abstract

The present invention discloses multiple microbe waste water treating agent and its waste water recovering and utilizing process. The multiple microbe waste water treating agent consists of K2HPO4, KH2PO4, MgSO4.7H2O, CaCl2.2H2O, NH4Cl, DL-sodium malate, yeast extract paste, EDTA-2Na, FeSO4.7H2O, H3BO4, CaCl2.6H2O, ZnCl2, biotin, nicotinic acid, L-sodium glutamate, growth factor liquid, trace element liquid, MnCl2.2H2O, Na2MoO4.2H2O, NiCl2.6H2O, CuCl2.2H2O, p-aminobenzoic acid, vitamin B1, vitamin B2, vitamin B6 and water. When the waste water treating agent is used in treating waste water, optimized microbe seeds are thrown in certain proportion. The present invention is used in treating waste water from plant fiber degradation with biological enzyme, and has high treating effect, short treating period and low treating cost.

Description

technical field [0001] The invention relates to a waste water treatment agent and a method for recycling waste water by using the treatment agent, in particular to a waste water treatment agent for treating degraded plant fibers by mixing biological multi-bacteria and a method for recycling and reusing the waste water. Background technique [0002] At present, the raw material of biological pulping is plant fiber, and the most important link in the production process is to degrade the plant fiber. The pH of the degraded wastewater is alkaline, and the COD cr BOD 5 It will seriously exceed the standard, and it also contains many harmful components, such as phosphorus, ammonia nitrogen, suspended particles, pectin, lignin, etc. If it is not treated or discharged without proper treatment, it will cause serious pollution to the water body. Contents of the invention [0003] The invention provides a biological multi-fungus wastewater treatment agent and a method for recycling...
