Embodiment Construction

[0006] The composite microbial preparation provided by the present invention is realized by the following production process:

[0007] A conventional microbiological fermentation method is adopted, including selecting non-pathogenic microbial strains, inoculating them into their respective growth media, and carrying out step-by-step expansion culture. The culture temperature is 22-38°C, the culture time is 2-5 days, and then mixed to form a seed liquid, and the seed liquid is added to the product medium for static anaerobic culture. The ratio of the seed solution to the product culture medium is 3-20%, the culture temperature is 25-40 DEG C, and the culture time is 15-30 days. During the cultivation process, the first 7 days should be properly stirred and deflated every day. And detect the change of pH, if the pH is between 2.5-5.0, the product fermentation is completed, it can be divided into warehouses, and stored at room temperature and airtight.

Abstract

The invention relates to a composite microbial agent which is used for the sludge reduction of urban life sewage and industrial waste water treatment, which mainly contains photosynthetic bacterium colony, yeast bacterium colony, lactic acid bacterium colony, propionic acid bacillus colony, antinomycetes bacterium colony, fungus and the like which are beneficial to humans, animals and plants. By the specific culture mediums and culture technology, microorganisms with different anaerobic, facultative anaerobic and aerobic characteristics commonly live and exist in the same culture medium, and mutually benefit, compliment and cooperate. The production method adopts a microbiological fermentation method. The production steps comprise that strictly selecting microbial strains for production, slope storage, amplifying culture of seed liquid, product static state culture, vital cell counting, quality detection and packaging and storage. The production process of the agent has no 'three wastes' pollution, and belongs to 'clean production'. The agent does not contain any disease bacteria, and has no toxicity, harm and irritant.

Description

technical field [0001] The invention relates to an environment-friendly compound microbial preparation used for sludge reduction in urban domestic sewage and industrial wastewater treatment. technical background [0002] In recent years, biotechnology has made great progress in the field of treatment of urban domestic sewage, such as A / O, A 2 / O, oxidation ditch and other conventional biological treatment technologies, as well as biological treatment technologies such as SBR, CASS-SBR, ICEAS, DAT-IAT, UNITANK, Phostrip, and three-ditch oxidation ditch with good phosphorus and nitrogen removal effects. As far as urban domestic sewage is concerned, there is no difficulty in treating up to the standard discharge, or even reusing reclaimed water, with the current technology. The difference between various processes lies only in economic indicators such as investment, land occupation, and operating costs. . [0003] The biological treatment method used in the current sewage tre...
