Problems solved by technology

The composition of industrial wastewater is complex, especially a large number of artificially synthesized compounds entering the environment, such substances are mainly alkanes, olefins, alicyclic hydrocarbons, aromatic hydrocarbons, and artificially synthesized organic substances, especially macromolecules, refractory, toxic and harmful Substances such as phenol, chlorophenol, cresol, nitrophenol, etc., aromatic hydrocarbons, cyanides, amines, and ammonia nitrogen enter the environment with the wastewater or solid waste discharged from the factory. Due to the complexity of the structure of these substances and their biological Strangeness cannot be decomposed and utilized by microorganisms in a short period of time. The traditional wastewater treatment method using activated sludge to cultivate domesticated microorganisms can no longer effectively remove these pollutants. These substances have accumulated in the environment for a long time and provide us with survival The ecological environment has caused great pollution, which has brought great harm to human physical and mental health.

Embodiment 3

[0035] Contrast test: the processing sample is an example with the industrial waste water of the municipal sewage treatment plant, and both the control group and the test group use the mixed liquid prepared in embodiment 2;

[0036] Control group: diatomite carrier (2:1 mass ratio with the mixed liquid); after three days of continuous dosing, 5g / m3 per day, and then stand still for six days, and test the treatment results.

[0037] Test group: microbial carrier of Example 2 of the present invention (with the mixed liquid at a mass ratio of 2:1); after one day of dosing, 5g / m3, and then stand for six days, and test the treatment results. The detection indicators of wastewater are shown in Table 1:

[0038] Table 1

[0039]

[0040] Conclusion: The specific surface area of ​​the microbial carrier of the present invention is more than twice that of the conventional diatomite carrier, the microbial adhesion effect is good, and the number of feeding times and weight are ...

Abstract

The invention belongs to the field of biotechnologies, and discloses a biological preparation for monitoring and treating industrial waste water. A method for manufacturing the biological preparation includes 1), weighing raw materials; 2), smashing and grinding the raw materials; 3), stirring and drying the raw materials; 4), manufacturing mixed liquid; 5), manufacturing the biological preparation. The biological preparation has the advantages that ammonia nitrogen, sulfide and aniline substances in the industrial waste water can be effectively removed by the biological preparation, and accordingly emission standards can be completely met.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a biological agent for monitoring and treating industrial waste water. Background technique [0002] Industrial wastewater includes production wastewater and production sewage, which refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. The composition of industrial wastewater is complex, especially a large number of artificially synthesized compounds entering the environment, such substances are mainly alkanes, olefins, alicyclic hydrocarbons, aromatic hydrocarbons, and artificially synthesized organic substances, especially macromolecules, refractory, toxic and harmful Substances such as phenol, chlorophenol, cresol, nitrophenol, etc., aromatic hydrocarbons, cyanides, amines, and ammonia n...
