Problems solved by technology

[0003] The composition of industrial sewage is more 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 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 p

Embodiment 3

[0071] In the Linyi Sewage Treatment Plant, using a 50L bucket as the test equipment with stirring, take three 30L water from the explosion pool and add them to the three buckets respectively, adjust the pH to 7.0, and the water temperature is 20°C. Samples are taken to measure COD, ammonia nitrogen, and total nitrogen. Count; COD before processing is 57mg / L, and ammonia nitrogen is 10mg / L, and total nitrogen 30mg / L; Wherein a bucket adds the bacterial agent 20ml that embodiment 1 prepares, another adds the microbial agent 20ml that embodiment 2 prepares, stirs 1 hour, stop stirring after 3 hours and take a sample to measure COD, ammonia nitrogen, total nitrogen number.

Abstract

The invention relates to a biological agent for processing industrial sewage, a preparation method of the biological agent and application. The biological agent is prepared by the following raw materials in percentage by weight; 32% of rhodococcus, 20% of bacillus subtilis, 10% of pseudomonas aeruginosa, 10% of saccharomyces cerevisiae, 10% of nitrosobacteria, 8% of bacillus megatherium, 5% of aspergillus niger and 5% of paracoccus denitrificans. According to the biological agent provided by the invention, the strains are reasonably matched, symbiotic and coordinative and out of antagonism; after being added to a sewage treatment system, the strains are good in effect of degrading macromolecular toxic and harmful substances which are hardly degraded, such as phenols, aromatichydrocarbons, ammonia nitrogen and phosphorus; and the biological agent has unique effect of processing high-concentration organic sewage and high-ammonia nitrogen sewage which are hardly processed by the conventional activated sludge process.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a biological bacterial agent for treating industrial sewage, a preparation method and application thereof. Background technique [0002] 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 removal treatment technology...
