Embodiment 2

[0050] After the wastewater is pretreated in the regulating tank, it enters the anaerobic system. The hydraulic retention time of the wastewater in the anaerobic system is 3 days, and then enters the aerobic biochemical system. The hydraulic retention time of the wastewater in the aerobic biochemical system is 1 day. After treatment, the wastewater enters the secondary sedimentation tank. After the treatment reaches the standard, the wastewater is discharged out, and the sludge is reused or discharged after the secondary treatment. In this experiment, water was continuously fed for a week, and facultative anaerobic bacteria were added to the anaerobic system and aerobic bacteria were added to the aerobic system at the same time every day. Monitor the changes in the number of viable bacteria in the anaerobic system, effluent COD, pH, etc. every day; monitor the changes in the number of viable bacteria in the aerobic system, the water quality data of the secondary sedimentation t...

Abstract

The invention discloses a method for treating sorbic acid wastewater and dehydroacetic acid comprehensive wastewater, which comprises wastewater pretreatment and comprises the following steps: mixing sorbic acid wastewater and dehydroacetic acid wastewater which are pretreated by a regulating tank, feeding into an anaerobic system, adding a powdery facultative anaerobic bacterium agent into the anaerobic system, and carrying out anaerobic treatment on the mixed wastewater; the microbial agent is a mixture of micrococcus, acinetobacter, pseudomonas and bacteroides. Then the wastewater enters an aerobic biochemical system, a powdery aerobic microbial agent is added into the aerobic biochemical system, and the powdery aerobic microbial agent is a mixture of four kinds of bacteria including acinetobacter, pseudomonas, pseudomonas stenotrophora and bacteroides; feeding the treated wastewater into a secondary sedimentation tank, discharging the wastewater reaching the standard after treatment, and recycling or discharging the sludge after secondary treatment. Under the condition of existing sewage treatment facilities, other process sections do not need to be added, and the purpose of sewage treatment can be achieved only by adding microbial agents into anaerobic and aerobic process sections, so that the cost investment is reduced; through reasonable proportioning of the microbial inoculum, the passage stability is good, and the stable operation of a sewage treatment system is ensured.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a treatment method for sorbic acid wastewater and dehydroacetic acid comprehensive wastewater. Background technique [0002] Both sorbic acid and dehydroacetic acid are food preservatives and have inhibitory effects on yeast, mold and aerobic bacteria. The wastewater generated from the production of the two products contains a small amount of the two finished products, as well as a large amount of production raw materials and intermediates. These substances cause great damage to the sewage treatment biochemical system, and even the system collapses. The current treatment technology is mainly aimed at the separate treatment of sorbic acid production wastewater and dehydroacetic acid wastewater, and the two kinds of wastewater are mixed for treatment, and there is no relevant literature report for the time being. Two separate wastewater treatment technologies are mainly chemic...
