After passing through the raw water collection tank, the waste water from the PCR laboratory is transferred to an equalization tank. It is then evenly pumped into the neutralization reaction unit via anti-corrosion and lifting pumps. A quantitative solution is added based on the water quality characteristics to initiate neutralization reactions. The neutralized waste water is then poured into a clarification reaction unit for sedimentation, followed by overflow redox reactions in the next unit. Anti-corrosion boosting pumps feed the filtered water into a filter barrel to enhance filtration efficiency. The filtered water is further treated by an ozone generator to intercept and adsorb micro-pollutants before being discharged directly into the urban sewage pipeline.
