Problems solved by technology

[0004] At present, industrial wastewater treatment methods mainly include physical methods such as reverse osmosis, distillation, and soil irrigation; chemical methods include ion exchange, ammonia stripping, chemical precipitation, breakpoint chlorination, electrodialysis, electrochemical treatment, and catalytic cracking; biological methods include Nitrification and algae cultivation, however, the physical treatment effect is not good. Compared with the chemical method, the biological method has the following advantages: 1) Each chemical product is a highly targeted product, and when it encounters other chemical substances, there will be may be ineffective, and biological agents have a spectrum in the removal of pollutants; 2) chemical products can temporarily eliminate some harmful substances and cover up odors, but cannot prevent the formation of harmful substances; 3) after using chemical products, there will be Residues may cause secondary pollution

Embodiment 1

[0029] A biological agent for the treatment of industrially polluted water bodies, the bacterial agent includes the following raw materials: a composite microbial bacterial agent and a carrier, and the composite microbial bacterial agent is composed of Pseudomonas putida, Candida, Bacillus amyloliquefaciens, Clostridium papyrisolubles , Nitrosifying bacteria, denitrifying paracoccus, nitrifying bacteria, denitrifying bacteria preparation.

[0030] The carrier is formed by mixing diatomaceous earth and peat soil in a weight ratio of 4:1;

[0031] The composite bacterial agent and the carrier are mixed according to a weight ratio of 1:3 to prepare a biological preparation;

[0032] The preparation method of the composite microbial bacterial agent is as follows: respectively culturing Pseudomonas putida, Candida, Bacillus amyloliquefaciens, Clostridium papyrisolubles, nitrosobacterium, denitrifying paracoccus, nitrifying bacteria and denitrifying bacteria to a concentration of 1...

Embodiment 2

[0045] In a sewage treatment plant, using a 50L bucket as the test equipment with stirring, take three 30L water from the explosion pool, add them to two buckets respectively, adjust the pH to 7.0, and water temperature 20°C, take samples to measure COD, ammonia nitrogen, and total nitrogen data COD before processing is 123mg / L, and ammonia nitrogen is 37mg / L; Test group adds the biological preparation 10g that embodiment 1 prepares and stirs 1 hour, stops stirring after 3 hours sampling and measures COD, ammonia nitrogen data; Blank control adds the water of equal weight, The operation was the same as that of the experimental group. The specific results are shown in Table 1:

[0046] Table 1

[0047]

Embodiment 3

[0049] The biological preparation prepared in Example 1 is used to treat the industrial wastewater of a chemical plant. The treatment process is A / O+sedimentation+biological aerated filtration. 20 grams of the preparation was added once a day for 10 consecutive days; 20 grams of the biological agent prepared in Example 1 was added to the biological aerated filter per cubic meter of filler, once a day for 10 consecutive days; Months later, the treatment effect is as follows:

Abstract

The invention relates to a biological agent for treatment of industrial polluted water. The biological agent comprises a composite microbial agent and a carrier, wherein the composite microbial agent is prepared from pseudomonas putida, candida utilis, bacillus amyloliquefaciens, clostridium papyrosolvens, nitrosomonas europaea, paracoccus denitrificans, nitrobacter sp. and paracoccus pantotrophus. The strains are reasonably matched, symbiotic and harmonious and is not mutually antagonistic, the biological agent has a good degradation effect on aniline compounds difficult to degrade after being fed into a wastewater treatment system and is suitable for treatment of the industrial polluted water, the water treatment capacity is increased, the quality of treated water is improved, operation expenses are reduced, and up-to-standard emission is realized.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a biological preparation for industrially polluted water treatment. 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. The composition of industrially polluted water bodies 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 Harmful substances such as phenol, chlorophenol, cr...
