Laboratory wastewater contains acid, alkali, organic pollutants, heavy metal ions, pathogenic microorganisms, large changes in PH value, high COD concentration, is divided into three main categories:
1, organic wastewater: the main source of experimental reagents, solvents;
2, inorganic wastewater: the main source of acid and alkali reagents, heavy metal reagents;
3, biological pathogenic wastewater: the main source of microbial culture, blood biochemical experiments, blood stations, CDC and so on.
Laboratory wastewater treatment of more mature methods and equipment:
1, heavy metal coagulation **** sedimentation process: removal of heavy metals, suspended solids, chromaticity;
2, PH automatic adjustment process: acid and alkaline wastewater automatic adjustment of PH value;
3, ozone oxidation and disinfection process: degradation of organic wastewater, removal of COD, kill E. coli;
4, medical wastewater according to the requirements of chlorine dioxide;
5, laboratory wastewater treatment and purification devices: integrated combination of processes, fully automatic operation.
