STUDY THE INFLUENCE OF CONCENTRATION OF COMPONENTS ON THE LEVEL OF WASTEWATER TREATMENT

The effect of the nature and concentration of coagulants on the effectiveness of reducing the colour intensity with varying the concentration of sorbent from 1 to 3 g/l and coagulants Al2(SO4)3 and FeCl3, respectively 0.5; 0.75 mg/l. It has been shown that from the mentioned reagents the optimal option is the use of aluminium sulfate and iron chloride as a coagulant, as a flocculant - anionic polyacrylamide in concentrations of 0.5 mg/l, 0.75 mg/l and 0.5 mg/l respectively. It is determined that application of coagulants and flocculant for treatment of wastewater of silkworm production makes it possible to achieve required parameters of quality of treatment, at that efficiency of treatment on suspended substances makes 94.0-97.0%, on COD 87.0-91.0%, on dyes 91.0-94.0%.
