Embodiment 1

[0027] The waste water of a certain kimchi enterprise is collected. After testing, the waste water of the enterprise does not meet the discharge standard and needs to be treated before being discharged. The waste water of the above-mentioned enterprise is treated by the waste water treatment agent and waste water treatment method of the present invention. The specific steps are as follows:

[0028] The kimchi wastewater treatment method includes the following steps:

[0029] (1) Filtration: filter with grille;

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

[0031] (3) The activated sludge method treats the wastewater in step (2), puts the wast...

Embodiment 2

[0039] The kimchi wastewater treatment method includes the following steps:

[0040] (1) Filtration: filter with grille;

[0041] (2) Precipitation: In the precipitation step, add the following parts by weight of Feng's physical water purifier, activated carbon is 1, organically modified zeolite is 1, and polyacrylamide 1; stirring while adding, the stirring speed is 10r / min; stirring; Let it stand for 1 hour after being uniform; the physical water purifying agent is 0.005% of the total weight of the waste water;

[0042] (3) The activated sludge method treats the wastewater in step (2), puts the wastewater in step (2) into an aeration tank, adds activated sludge containing composite microbial agents in the aeration tank, and then removes the activated sludge Put mud into the aeration tank;

[0043] In activated sludge, the composite microbial inoculants are: denitrifying Paracoccus powder 0.02, Rhodococcus powder 0.05, Bacillus megaterium 0.05 and Pseudomonas stutzeri powder 0.04. T...

Embodiment 3

[0046] The kimchi wastewater treatment method includes the following steps:

[0047] (1) Filtration: filter with grille;

[0048] (2) Precipitation: In the precipitation step, add the following parts by weight of Feng's physical water purifying agent, activated carbon is 5, organically modified zeolite is 5 and polyacrylamide 5; stirring while adding, the stirring speed is 20r / min; stirring; Let stand for 4 hours after being uniform; the physical water purifying agent is 0.02% of the total weight of waste water;

[0049] (3) The activated sludge method treats the wastewater in step (2), puts the wastewater in step (2) into an aeration tank, adds activated sludge containing composite microbial agents in the aeration tank, and then removes the activated sludge Put mud into the aeration tank;

[0050] In the activated sludge, the composite microbial inoculants are: denitrifying Paracoccus powder 0.1, Rhodococcus powder 0.2, Bacillus megaterium 0.2 and Pseudomonas stutzeri powder 0.2. Th...

Abstract

The invention belongs to the field of wastewater treatment for food enterprises and specifically relates to a pickles production wastewater treatment agent and also relates to a pickles production wastewater treatment method. The pickles production wastewater treatment agent comprises the following ingredients (by weight): a physical water purifier including 1-5 parts of active carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide; complex microbial inocula including 0.02-0.1 part of Paracoccus denitrificans powder, 0.05-0.2 part of rhodococcus powder, 0.05-0.2 part of bacillus megatherium powder and 0.04-0.2 part of pseudomonas-stutzeri powder; and an enzymic preparation including 0.05-0.1 part of lignan hydroxylase, 0.04-0.09 part of pectase and 0.01-0.06 part of papain. By the use of the wastewater treatment agent and the wastewater treatment method, complex, hardly-degradable and large-grained organic matters are hydrolyzed into simple easily-degradable organic matters, content of SS in wastewater is greatly reduced, BOD and COD removal rate of wastewater after treatment is high, and specified emission standard is reached.

Description

Technical field [0001] The invention belongs to the field of wastewater treatment in food enterprises, and specifically relates to a kimchi production wastewater treatment agent, and also relates to the above-mentioned kimchi production wastewater treatment method. Background technique [0002] The waste water in the production of kimchi food factory mainly includes waste water generated during the production of kimchi and domestic sewage discharged from the office area. The waste water has obvious seasonal and daily differences, and the water quality fluctuates greatly, and the concentration of suspended solids in the waste water is high. The salinity is about 5% (as NaCl), which belongs to wastewater with high salinity, high organic matter, and high nitrogen and phosphorus. Due to the high pollution (COD, BOD, SS) and high salt content of kimchi wastewater, biodegradation cannot be used in the treatment process; general physical and chemical treatment such as flocculation and s...
