Problems solved by technology

[0006] 2. SO 4 2- Inhibition of the anaerobic system
The pollution of the watershed is largely caused by eutrophication. Effective removal of ammonia nitrogen can solve this problem well. In China, nitrification and denitrification process is widely used. According to theoretical calculations, 3-4kg of alkali is required for the removal of ammonia nitrogen per kilogram. , most processes also need to add carbon sources for denitrification and denitrification, resulting in high operating costs or failure to operate normally

Embodiment 1

[0135] Embodiment 1: preparation is used to handle the microbial preparation of difficult waste water

[0136]After the activated sludge is screened and domesticated by microorganisms in the laboratory, the screened strains are mixed, and the anaerobic bacteria combination and the aerobic bacteria combination are matched in a ratio of 1:1, and the mixed bacteria are ensured The seed mixture contains 105 bacterial strains disclosed in the present invention, and then the mixed flora is divided into two halves, and aerobic fermentation culture and anaerobic fermentation culture are respectively carried out.

[0137] Among them, three kinds of culture medium are used for aerobic culture, which are respectively bacterial complete medium (such as beef extract peptone medium), glucose complete medium, and sucrose inorganic salt medium. The three kinds of medium are respectively inoculated and cultured, and the culture condition is 30 ° C. , 120 rev / min, and the time is 36 hours. Afte...

Embodiment 2

[0143] Embodiment 2: preparation is used to handle the microbial preparation of difficult waste water

[0144] The pH of the three mediums used in the aerobic culture was adjusted to 7.4 and sterilized at 121° C. for 15 minutes. The culture conditions of the aerobic culture were 32° C., 120 rpm, and the time was 24 hours. The culture temperature of the anaerobic culture is 32° C., stirring for 5 minutes every two hours, and the culture time is 48 hours. All the other preparation conditions and preparation steps are the same as in Example 1.

Abstract

A microbiological preparation made from 105 types of acclimatized and integrated microorganisms belonging to 47 genuses can be used to process highly difficult waste waters of coking waste water, gourment powder waste water, antibiotic waste water, pigment waste water, paper making waste water and fluorating waste water.

Description

technical field [0001] The invention relates to a microbial preparation for wastewater treatment and a preparation method thereof. Background technique [0002] The so-called difficult wastewater refers to high COD content, while BOD 5 (Biochemical oxygen demand) is relatively low and contains toxic waste water. Mainly distributed in oil refining industry, petrochemical industry, dye and dyeing and finishing industry, pharmaceutical industry (especially antibiotic manufacturing industry), pesticide industry, monosodium glutamate industry, coking industry, pulp manufacturing industry, wool spinning industry, chemical manufacturing industry, rubber industry, etc. Because toxic substances often have a strong inhibitory effect on microorganisms, it is often difficult to meet the treatment requirements for difficult wastewater treated with ordinary activated sludge. Poor physical adaptability, unable to completely decompose various pollutants. [0003] At this stage, there are...
