Hot-pickled mustard tuber production wastewater treating agent and wastewater treating method

Abstract

The invention belongs to the field of food enterprise wastewater treatment and particularly relates to a hot-pickled mustard tuber production wastewater treating agent and a hot-pickled mustard tuber production wastewater treating method. The hot-pickled mustard tuber production wastewater treating agent is prepared from, by weight, a physical water purifying agent, a composite microbial agent and an enzymic preparation. The physical water purifying agent is prepared from, by weight, 1-5 parts of activated carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide. The composite microbial agent is prepared from, by weight, 0.02-0.1 part of halophilic pseudomonas powder, 0.05-0.2 part of aspergillus flavus powder, 0.05-0.2 part of bacillus licheniformis powder and 0.04-0.2 part of paracoccus aminovorans powder. The enzymic preparation is prepared from, by weight, 0.05-0.1 part of cellulose, 0.04-0.09 part of pectinase and 0.01-0.06 part of thioesterase. By means of the wastewater treating agent and the wastewater treating method, organic matter which is complex, difficult to degrade and large in particle 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 wastewater reaches the regulated emission standard.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, and in particular relates to a mustard production wastewater treatment agent, and also relates to the above-mentioned mustard production wastewater treatment method. Background technique [0002] At present, the treatment of mustard wastewater produced in the mustard production process has attracted more and more attention. For example, about 3.5 million tons of wastewater are produced in the mustard processing process in Fuling District every year, and the concentration of organic pollutants in mustard wastewater is as high as 10-20 grams per year. liters, the concentration of suspended solids is as high as 7 grams per liter, and the salt concentration is as high as 2-5%. These wastewaters have not been effectively treated, and they are scattered and discharged to various sewage outlets, causing serious pollution to the urban water environment. In addition, the treatment of...

[0002] At present, the treatment of the mustard wastewater produced in the mustard production process has attracted more and more attention. For example, about 3.5 million tons of wastewater are produced in the mustard processing process in Fuling District every year, and the concentration of organic pollutants in the mustard wastewater is as high as 10-20 grams per year. liters, the concentration of suspended solids is as high as 7 grams per liter, and the salt concentration is as high as 2-5%. These wastewaters have not been effectively treated, and they are scattered and discharged to various sewage outlets, causing serious pollution to the urban water environment. In addition, the treatment of pickled mustard wastewater is more difficult. Large, there is no suitable treatment method at present, and the blank of mustard wastewater treatment technology will restrict the development of mustard industry, which has become an urgent problem to be solved in the mustard production industry. The advanced mustard mustard wastewater treatment technology will not only fill the gap in my country's mustard mustard wastewater treatment technology, but also have a profound impact on the sustainable development of my country's mustard mustard industry
