Embodiment 1

[0036] (1) Take the monosodium glutamate wastewater produced by the concentrated isoelectric process, and the wastewater enters the pre-anaerobic pool UASB, and the hydraulic retention time is controlled to be 20h, and the temperature is 30°C, so that the macromolecular substances are broken into small molecules Substances, organic nitrogen is converted into inorganic nitrogen, and the effluent enters the sedimentation tank;

[0037] (2) Add bioremediation preparation to the sedimentation tank for advanced treatment, and the bioremediation preparation includes the following raw materials in parts by weight:

[0038] 7 parts of nitrosifying bacteria, 7 parts of aerobic denitrifying bacteria, 5 parts of Acinetobacter baumannii, 5 parts of Aspergillus niger, 5 parts of Rhodococcus, 3 parts of Alcaligenes faecalis, 3 parts of Streptomyces rubrum, Candida albicans 3 parts, Paenibacillus polymyxa 2 parts.

Embodiment 3

[0075] Embodiment 3 treats waste water effect example

[0076] Get monosodium glutamate to extract wastewater, enter the sewage treatment system according to the method of embodiment 1-2 respectively, and the bottom material of the kettle, sample and measure COD, ammonia nitrogen, sulfide data;

[0077] Compared with Example 1, the control group 1 did not add compound bacterial agents; compared with Example 2, the control group 2 had only straw as the adsorbent carrier, and compared with Example 2, the control group 3 had only humic acid as the adsorbent carrier. Sampling and determination of COD, ammonia nitrogen, and sulfide data, the test data are as follows in Table 1:

Abstract

The invention relates to bioremediation preparation for industrial waste water produced by using the concentration isoelectric point technology to prepare sodium glutamate. The bioremediation preparation is mixed and prepared by nitrosomonas europaea, paracoccus pantotrophus, acinetobacter baumannii, aspergillus niger, rhodococcus sp., alcaligenes faecalis, streptomyces lateritius, candida albicans, paenibacillus polymyxa and an absorbent carrier. The bioremediation preparation has the advantages that the preparation contains various microorganisms with good degrading ability to degradation-resistant pollutants, various strains are reasonably combined, and the preparation is good in degrading effect and promising in application prospect.

Description

technical field [0001] The invention relates to the field of wastewater treatment by microbial preparations, and specifically provides a bioremediation preparation for preparing industrial wastewater produced by sodium glutamate using a concentrated isoelectric point technology. Background technique [0002] my country is a big producer and consumer of monosodium glutamate. At present, various economic and technical indicators have reached or approached the world's advanced level. With the rapid development of the MSG industry, the regional structure of MSG production is constantly changing. Nowadays, my country's monosodium glutamate industry has shown a relatively high degree of concentration, but with the implementation of national industrial policies, the state's efforts to control corporate pollution have increased, and people's misunderstanding of the health of monosodium glutamate , the MSG industry will also face adjustments, and some small and medium production ca...
