Method for processing preserved kumquat processing waste water rich in salts and organic matters

Abstract

The invention discloses a method for processing preserved kumquat processing waste water rich in salts and organic matters. The method mainly comprises following six steps: (1) adding quicklime into waste water, and stirring to fully carry out reactions; (2) filtering the solution by a micro filtration machine; (3) adding quicklime, PAC, and PAM, and carrying out coagulation air floatation; (4) adding H2SO4 to adjust the pH to 8.5; (5) inoculating halophilic microorganisms to carry out anaerobic baffle board reactions (ABR); and (6) carrying out halophilic primary contact oxidation and halophilic secondary contact oxidation. By adding medicaments, under the cooperative effect of micro filtration machine and coagulation air floatation, suspensions such as fruit dregs, coked calcium sulfite, and the like, and part of macromolecular organic matters are effectively removed, and an ideal pretreatment effect is guaranteed. The problems that common active sludge cannot exist in waste water rich in salts and organic matters and the biochemical treatment effect is bad are solved.

Description

technical field [0001] The invention relates to the field of food processing sewage treatment, in particular to a treatment method for processing waste water of kumquat candied fruit with high salt and high organic matter. Background technique [0002] Among the industrial wastewater pollution, the pollution of food industry wastewater deserves attention, the most typical one is the wastewater pollution of pickled food. If preserved products, candied fruit, pickled mustard, braised vegetables and other pickled products, these foods will generate a lot of waste water during the production process, especially the pickling process will produce a large amount of high-concentration organic waste water and high-concentration brine. These sewage contains a large amount of pollutants such as sugar, pectin, pomace, organic acid, mineral salt, COD Cr As high as 10000mg / L or more, there is also a high concentration of table salt, the concentration is as high as 20g / l00mL, which is a h...

AI Technical Summary

Problems solved by technology

Isolate and cultivate halophilic microorganisms from these natural high-salt environments, construct a halophilic microbial community that can efficiently degrade pollutants in a high-salt environment, and apply it to high-concentration saline organic wastewater, fundamentally solving the problem of high-salt and high-salt environment. The general activated sludge in organic waste water cannot survive and the biochemical treatment effect is poor
