Problems solved by technology

[0005] The composition of industrial sewage is more complex, especially a large number of artificially synthesized compounds entering the environment, such substances are mainly ammonia nitrogen, aromatic hydrocarbons, olefins, alicyclic hydrocarbons, artificially synthesized organic substances, especially macromolecules, refractory, toxic 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 the biological The unfamiliarity of these pollutants 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, giving us The living ecological environment has caused great pollution, which has brought great harm to human physical and mental health.
Due to the difficulty of sewage treatment and the large investment, a considerable number of industrial polluting enterprises in our country would rather accept huge fines than invest in waste water treatment. Even if there is a sewage treatment plant, the operation is extremely abnormal.

Abstract

The invention belongs to the field of wastewater treatment and discloses a treatment process applicable to industrial wastewater. The treatment process applicable to the industrial wastewater comprises the following steps: 1) preparing complex microbial inoculant; 2) precipitating wastewater; 3) purifying the wastewater; 4) preparing bacterial manure. The prepared complex microbial inoculant comprises 5-6 parts of micrococcus luteus, 4-5 parts of bacillus mucilaginosus, 3-4 parts of paracoccus denitrificans, 2-3 parts of rhodococcus, 2-3 parts of acidithiobacillus ferrooxidans, 1-2 parts of bacillus megaterium and 1-2 parts of bacillus cereus. The invention also discloses bacterial manure prepared by utilizing the treatment process applicable to the industrial wastewater. The treatment process applicable to the industrial wastewater is simple and feasible, the industrial wastewater can be effectively treated, and the bacterial manure is prepared by utilizing the treatment process applicable to the industrial wastewater.

Description

[0001] technical field [0002] The invention belongs to the technical field of environmental protection, and in particular relates to a treatment process for industrial sewage and its application in the preparation of bacterial fertilizer. [0003] Background technique [0004] With the increasing urban population and the continuous development of industry and agriculture, water pollution accidents occur frequently, seriously endangering the health and even life of people and animals. The discharge of nitrogen and phosphorus in many lakes and reservoirs has caused water eutrophication, which seriously threatens human production, life and ecological balance. Ammonia nitrogen is one of the main factors causing water eutrophication. In order to meet the continuous improvement of the public's requirements for environmental quality, the country has formulated more and more stringent emission standards for nitrogen. Research and development of economical and efficient nitrogen ...
