Laboratory wastewater treatment technology
Laboratory sewage is the comprehensive wastewater which mainly produced in the process of laboratory drugs, reagents, test liquid, waste liquid, residual reagent, container washing, instrument cleaning and leakage. Compared with industrial wastewater and domestic sewage,it has the characteristics of small amount and strong pollution.
Production Introduction
According to the quality of this kind of wastewater, the process of “catchment tank +pH regulation + aeration micro-electrolysis + flocculation +pH regulation + disinfection + filtration” can be adopted.After processed, the wastewater can meet the discharge standard of “Quality Standard for Sewage Discharge into Urban Sewers” [GB/T31962-2015]. That is, CODcr≤300mg/l, BOD5≤150mg/l, SS≤100mg/l, NH3-N≤25mg/l, TN≤45.0mg/l, TP≤5.0mg/l.
