Embodiment Construction
[0028] Such as Figure 1-2 As shown, a waste liquid treatment method of CMC or sodium creatine ammonia or laundry detergent, the waste liquid is saline waste water, and the saline waste water is evaporated by MVR to remove 80% of inorganic salts, and the rest is salty 10-15 %, water 40-50% and organic matter 35-50% solution, the chemical oxygen demand COD of this solution is as high as 300,000 mg / L or more, referred to as the mother liquor; the mother liquor is prepared into the chemical oxygen demand COD1 in the distribution tank 1 10,000-14,000 mg / L solution, and then the prepared wastewater is pumped into UASB pool 2 through pump 10 for treatment, and then flows into facultative oxygen pool 3, PACT pool 4, middle sedimentation pool 5, hydrolytic acidification in sequence through overflow Pool 6, contact oxidation tank 7 and secondary settling tank 8 are processed, and after the treatment is completed, detection and discharge are carried out; the middle settling tank 5 inclu...
