Problems solved by technology

If it is discharged randomly, on the one hand, it will waste water resources and increase the cost of pectin; on the other hand, it will pollute the environment
Because the pectin contained in the wastewater has poor settling properties, it is difficult to dehydrate, and the effect of direct microbial decomposition is not ideal, so it is difficult to use traditional flocculation sedimentation and activated sludge treatment methods

Embodiment 1

[0025] Collect the waste water of a certain pectin enterprise. After testing, the waste water of this enterprise does not reach the discharge standard, and it needs to be treated before being discharged. The waste water of the above-mentioned enterprise is treated by using the waste water treatment agent and the waste water treatment method of the present invention. The specific steps are as follows :

[0026] Pectin production wastewater treatment method comprises the following steps:

[0027] (1) Filtration: use grid sieve;

[0028] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, 3 for activated carbon, 3 for organically modified zeolite and 3 for polyacrylamide; stir while adding, and 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;

[0029] (3) Activated sludge method processes the waste water in the s...

Embodiment 2

[0037] Pectin production wastewater treatment method comprises the following steps:

[0038] (1) Filtration: use grid sieve;

[0039] (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;

[0040] (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;

[0041] In the activated sludge, the composite microbial bacterial agent is: 0.02 of the Pseudomonas bacterium powder, 0.05 of the Rhodococcus bacterial powder, 0.05 of the Chr...

[0044] Pectin production wastewater treatment method comprises the following steps:

[0045] (1) Filtration: use grid sieve;

[0046] (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;

[0047] (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;

[0048] In the activated sludge, the composite microbial bacterial agent is: 0.1 of Pseudomonas flexure powder, 0.2 of Rhodococcus bacterial powder, 0.2 of Chryseobacterium bac...

Abstract

The invention belongs to the food industry wastewater treatment field, particularly relates to a pectin production wastewater treatment agent, and further relates to a pectin production wastewater treatment method. The pectin production wastewater treatment agent includes the following components in parts by weight: a physical water purifier comprising 1-5 parts of activated carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide; a compound microbial agent comprising 0.02-0.1 part of a pseudomonas geniculata powder, 0.05-0.2 part of a rhodococcus powder, 0.05-0.2 part of a flavobacterium indologenes powder and 0.04-0.2 part of a thiobacillus powder; and an enzymic preparation comprising 0.05-0.1 part of cellulase, 0.04-0.09 part of pectase, and 0.01-0.06 part of ficin. By adopting of the wastewater treatment agent and the wastewater treatment method, complex, difficult-to-degrade and large-particle organic matters are hydrolyzed into easy-to-degrade simple organic matters, the content of SS in wastewater is greatly reduced, the BOD and COD removal rate of the treated wastewater is high, and prescribed discharge standards are reached.

Description

technical field [0001] The invention belongs to the field of waste water treatment in food enterprises, and in particular relates to a pectin production waste water treatment agent, and also relates to the above-mentioned pectin production waste water treatment method. Background technique [0002] Pectin production process produces a large amount of wastewater, which contains a large amount of fibrous substances, sediment, protopectin, cellulose, hemicellulose, etc., and cannot be used directly for production. If it is discharged at will, on the one hand, it will waste water resources and increase the cost of pectin; on the other hand, it will pollute the environment. Because the pectin contained in the wastewater has poor settling properties, it is difficult to dehydrate, and the effect of direct microbial decomposition is not ideal. Therefore, it is difficult to use traditional flocculation sedimentation and activated sludge treatment methods. Contents of the invention ...
