Integrated industrial wastewater treatment
For some chemical wastewater for biochemical treatment has a certain impact, resulting in poor direct biochemical treatment, Tepaul Environmental Protection and Energy Conservation Technology Co., Ltd. has a unique treatment process for such wastewater, and pretreatment + MVR evaporation + compound oxidation + hydrolysis acidification + anaerobic + aerobic. After the wastewater is evaporated, most of the organic matter exists in the evaporation mother liquor, and the condensate after evaporation only contains a small amount of low boiling point, small molecular chain organic matter, and the biochemical treatment effect is good.
An industrial wastewater comprehensive treatment, wastewater contains high saline water, production process wastewater, domestic sewage, etc.; raw water quality: PH:7.07; density 1.013g/ml; CODcr:2060mg/L; BOD5:998mg/L; TDS:9.45g /L; ammonia nitrogen:150g/L; hardness:408mg /L (in Ca); where the salinity of brine About 2.2%; our company treats its wastewater according to its characteristics, and the high saline water is evaporated and crystallized separately, because the condensate after evaporation entraps some low boiling point organic matter, the condensate COD is higher, so the evaporated condensate mixed process production wastewater enters the biochemical treatment system; the biochemical treatment adopts AO process to reduce the wastewater ammonia nitrogen, organic matter, etc., and the effluent index is good, and the project has been successfully discharged since 2017 The project has been successfully discharged since 2017, with stable and normal operation, and the average cost of ton water treatment is about 2.9 yuan/ton water.
