Problems solved by technology

Vinegar wastewater is characterized by high organic matter concentration, high ammonia nitrogen concentration, and high chroma. Direct discharge will cause great harm to the environment. Organic matter and ammonia nitrogen are the main pollution indicators for water pollution control in my country. The pollution caused by these pollutants Water pollution, environmental pollution and threats to human health are relatively serious, and due to the small scale of the vinegar production industry in the past and the special geographical environment, there is insufficient understanding of the characteristics and treatment technologies of its production wastewater. There are certain defects, the discharge of production wastewater is also increasing, and the impact on water pollution is becoming more and more serious.
Especially the high amm

Embodiment 1

[0027] Collect the wastewater of a certain vinegar enterprise. After testing, the wastewater of this enterprise does not meet the discharge standard, and it needs to be treated before being discharged. The wastewater treatment agent and wastewater treatment method of the present invention are used to treat the wastewater of the above-mentioned enterprise. The specific steps are as follows :

[0028] Vinegar production wastewater treatment method comprises the following steps:

[0029] (1) Filtration: use grid sieve;

[0030] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, activated carbon is 3, organically modified zeolite is 3 and polyacrylamide 3; stir while adding, the stirring speed is 15r / min; stir After uniformity, let stand for 2.5 hours; the physical water purifying agent is 0.008% of the total weight of waste water;

[0031] (3) Activated sludge method processes the waste water in the step (2), puts the wa...

Embodiment 2

[0039] Vinegar production wastewater treatment method comprises the following steps:

[0040] (1) Filtration: use grid sieve;

[0041] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, 1 for activated carbon, 1 for organically modified zeolite and 1 for polyacrylamide; stir while adding, and the stirring speed is 10r / min; After uniformity, let it stand for 1 hour; the physical water purifying agent is 0.005% of the total weight of waste water;

[0042] (3) Activated sludge method processes the waste water in the step (2), puts the waste water in the step (2) into the aeration tank, adds the activated sludge containing the composite microbial bacterial agent in the aeration tank, and then the activated sludge Put the mud into the aeration tank;

[0043] In the activated sludge, the composite microbial agent is: Acidovorax konjac powder 0.02, sulfate reducing bacteria powder 0.05, Bacillus lysine powder 0.05 and Moraxe...

Embodiment 3

[0046] Vinegar production wastewater treatment method comprises the following steps:

[0047] (1) Filtration: use grid sieve;

[0048] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, 5 for activated carbon, 5 for organically modified zeolite and 5 for polyacrylamide; stir while adding, and the stirring speed is 20r / min; After uniformity, let it stand for 4 hours; the physical water purifying agent is 0.02% of the total weight of waste water;

[0049] (3) Activated sludge method processes the waste water in the step (2), puts the waste water in the step (2) into the aeration tank, adds the activated sludge containing the composite microbial bacterial agent in the aeration tank, and then the activated sludge Put the mud into the aeration tank;

[0050] In the activated sludge, the composite microbial agent is: Acidovorax konjac powder 0.1, sulfate reducing bacteria powder 0.2, Bacillus lysine powder 0.2 and Moraxella...

Abstract

The invention belongs to the field of food enterprises' wastewater treatment, particularly relates to a vinegar production enterprises' wastewater treating agent and further relates to a vinegar production wastewater treatment method. The vinegar production wastewater treating agent is prepared from, by weight, a physical water purifying agent including 1-5 parts of activated carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide, a compound microbial agent including 0.02-0.1 part of konjac acidovorax powder, 0.05-0.2 part of sulfate reducing bacterium powder, 0.05-0.2 part of lysine bacillus powder and 0.04-0.2 part of Moraxella powder, and an enzyme preparation including 0.05-0.1 part of xylanase, 0.04-0.09 part of Streptomyces protease and 0.01-0.06 part of acid protease. By the adoption of the wastewater treating agent and the wastewater treatment method, complex large-particle organic matter difficult to degrade is hydrolyzed into simple organic matter easy to degrade, the SS content in wastewater is greatly reduced, the BOD and COD removal rate of the treated wastewater is high, and the prescribed discharge standards are reached.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, and in particular relates to a treatment agent for vinegar production waste water, and also relates to the above-mentioned method for treating vinegar production waste water. Background technique [0002] Vinegar production is a traditional industry in my country, and its wastewater is a kind of organic wastewater with high organic matter concentration, high chroma, and ultra-high ammonia nitrogen. The current treatment technology still has certain limitations. Vinegar wastewater is characterized by high organic matter concentration, high ammonia nitrogen concentration, and high chroma. Direct discharge will cause great harm to the environment. Organic matter and ammonia nitrogen are the main pollution indicators for water pollution control in my country. The pollution caused by these pollutants Water pollution, environmental pollution and threats to human health are relati...
