Embodiment 1

[0031] A preparation for treating aniline wastewater, the preparation includes the following raw materials: a composite bacterial agent and a carrier, and the composite bacterial agent is composed of Pseudomonas putida, Candida, Bacillus amyloliquefaciens, Clostridium papyrisolubles, nitrosogens, Prepared by Trichoderma chrysogreen, nitrifying bacteria and denitrifying bacteria.

[0032] The carrier is formed by mixing diatomite and peat soil in a weight ratio of 3:1;

[0033] The composite bacterial agent and the carrier are mixed according to a weight ratio of 1:2 to prepare a bioremediation preparation;

[0034] The preparation method of the composite bacterial agent is as follows: Pseudomonas putida, Candida, Bacillus amyloliquefaciens, Clostridium papyrisolubles, nitrosative bacteria, Trichoderma chrysogenum, nitrifying bacteria, and denitrifying bacteria are respectively cultivated to a concentration of 1×10 8 bacterium solution per ml, and then mixed according to the ...

Embodiment 2

[0046] The method of using the preparation prepared in Example 1: put the solid preparation into the polluted water body of aniline, wherein the weight ratio of the solid preparation and the water body is 1:600, wherein the polluted water body of aniline is artificially prepared, and the initial concentration of aniline is 60mg / L, then shake culture under normal temperature for 24 hours, the concentration of aniline drops to 0.01mg / L, and the degradation rate reaches 99.9%.

Embodiment 3

[0048] The preparation prepared in Example 1 is used to treat the industrial sewage of a certain pharmaceutical factory. The concentration of COD in the sewage is 736mg / L, the concentration of dinitrotoluene + trinitrotoluene is 203mg / L, and the concentration of aniline is 75mg / L. Sewage is added 20 grams of the preparation prepared in Example 1 every time, and is added once a day. After 10 days of continuous addition, the treatment effect detected is as follows: the concentration of effluent COD is 10 mg / L, and the concentration of nitrobenzenes is 1 mg / L. Below L, the concentration of anilines is 0.01mg / L.

Abstract

The invention relates to a preparation for treating aniline waste water and a treatment method thereof. The preparation is prepared from pseudomonas putida, candida albican, bacillus amyloliquefaciens, paper dissolving clostridium, nitrosobacteria, trichoderma aureoviride, nitrifying bacteria, denitrifying bacteria and a carrier. Compatibility among the strains is reasonable, the strains grow together, coordinate, are not antagonistic, are placed into a waste water treatment system, have a good effect of degrading aniline compounds difficult to degrade and are suitable for industrial sewage treatment, the water treatment capacity is increased, the water treatment quality is improved, the operating cost is reduced, and the waste water reaches the standard and is discharged.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a preparation and a treatment method for treating aniline wastewater. Background technique [0002] Aniline is an important raw material in pharmaceutical, pesticide, dyestuff and other industries, and widely exists in the wastewater of these industries. Due to its very strong toxicity to humans and other organisms, many countries have strictly restricted the emission standards of aniline. now biodegradable [0003] It has become the preferred method for removing low-concentration aniline in wastewater. With the efforts of many researchers, people have isolated a variety of highly efficient aniline-degrading bacteria from the environment, and the pathways of aniline degradation by different bacteria may be different. [0004] The traditional treatment methods for aniline sewage generally include: [0005] Physical method: (1) Adsorption method. The adsorpt...
