Problems solved by technology

[0003] The applicant's previous invention patent technology "treatment process of monosodium glutamate fermentation waste water" discloses a process for effectively treating fermentation waste liquid, in which microbial agents are used, which are effective in treating COD, ammonia nitrogen, and SS, but there are strains in the agent Too much will increase the possibility of bacterial strain contamination, and it is relatively difficult to cultivate, and the amount of bacterial agent used is too large. Each ton of sewage needs to add 0.5-1kg of physical adsorbent and 15-20g of bacterial agent. The bacterial agent is easy to deposit to the bottom of the pool. Cause flocculation, resulting in a large amount of sludge, difficult to clean up

Embodiment 1

[0020] A kind of environment-friendly process of controlling monosodium glutamate fermentation waste liquid, it comprises the steps:

[0021] The sewage first enters the sedimentation tank and stands still for 12 hours. The bottom filler of the sedimentation tank is river sand with a thickness of 50cm. The particle size of the river sand is 1mm, which can initially adsorb and precipitate some flocculation impurities; Adjust the pH to 5 by adding ammonia water; then enter the phytoremediation tank, the repair time is 48h; then enter the microbial reaction tank, add 2 grams of microbial preparations per cubic meter of liquid, once a day, continuous dosing 5 days, then stand still for 3 days, and finally filter and discharge through a plate and frame filter; the plate and frame filter is used to collect microbial cells to avoid pollution to water bodies.

[0022] Such as figure 1 As shown, the phytorehabilitation pool is successively laid down from the bottom of the pool to a co...

Embodiment 2

[0029] A kind of environment-friendly process of controlling monosodium glutamate fermentation waste liquid, it comprises the steps:

[0030]The sewage first enters the sedimentation tank and stands still for 12 hours. The bottom filler of the sedimentation tank is river sand with a thickness of 50cm. The particle size of the river sand is 1mm, which can initially adsorb and precipitate some flocculation impurities; Adjust the pH to 8 by adding ammonia water; then enter the phytoremediation pool, the restoration time is 48 hours; then enter the microbial reaction pool, add 2 grams of microbial preparations per cubic meter of liquid, once a day, continuous dosing 5 days, then stand still for 3 days, and finally filter and discharge through a plate and frame filter; the plate and frame filter is used to collect microbial cells to avoid pollution to water bodies.

Embodiment 3

[0038] Example of the effect of the process of the present invention on the treatment of fermentation waste liquid:

[0039] Take the monosodium glutamate fermentation waste liquid (COD is 1327.2mg / L, ammonia nitrogen 201.7mg / L, sulfide 69.4mg / L) from the production workshop of Fufeng, Inner Mongolia, and take the process of Example 1 as an example to measure COD, ammonia nitrogen, and sulfide data; and a control group is set to detect the compatibility effect of each bacterial strain in the bacterial agent: control group 1: do not add Bacillus xylosoxidans, all the other are the same as Example 1; control group 2: do not add Micrococcus luteus, all the other are the same as the embodiment 1; Control group 3: without adding Nocardia corals, the rest is the same as in Example 1; Control group 4: without adding Cellulomonas, and the rest is the same as in Example 1. The specific test results are shown in Table 1:

Abstract

The invention belongs to the technical field of biology, and discloses an environment-friendly process for treating monosodium glutamate fermentation waste liquid. The environment-friendly process comprises the following steps: introducing sewage into a sedimentation basin, then introducing the sewage in an acidifying or alkalizing tank, adjusting the pH value between 5 and 8, then introducing the material into a plant restoration pool, then introducing the material into a microbe reaction tank, feeding a microbe preparation, and finally filtering the material and discharging the material. The process employs combination of a microbe technology and a plant restoration technology, reduces the investment amount of microbe and generation amount of sludge, soil can be restored, and double benefits can be realized.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an environmental protection process for treating monosodium glutamate fermentation waste liquid. Background technique [0002] Monosodium glutamate is a widely used food freshness enhancer. The production of monosodium glutamate by fermentation will produce a large amount of high-concentration waste liquid. low, the processing difficulty is extremely high, and the processing cost is extremely high. Therefore, many monosodium glutamate manufacturers fail to effectively treat monosodium glutamate waste liquid, which has brought great harm to the environment and social development. The problem is becoming more and more serious, and the treatment of MSG waste liquid has become a major problem restricting the development of MSG production enterprises. The main sources of MSG waste liquid are: waste mother liquor or ion exchange tail liquid after extracting glutamic acid from ...
