SELECTION OF OPTIMAL COMBINATION OF REAGENTS FOR TREATMENT OF WASTE WATER OF ACCUMULATOR PRODUCTION

university, Tyumen, e-mail: galinakachalova@mail.ru Studies were carried out using artificially created waste water, on the composition and properties of JSC «Tyu- men Battery Plant» repeating waste water. The aim is a comparative evaluation of effectiveness of action of different types of flocculants in combination with a certain coagulant on the process of waste water treatment, carrying out the process of sorption post-treatment before and after coagulation with subsequent determination of residual con-tent of lead. The used Flopam brand flokulyanta: Flopam 4125 SH, 4440 SH, Praestol brand flokulyanta: Praestol 2531 TR, 650 TR, флокулянт Na 2 O liquid glass · mSiO 2 · nH 2 O. The used coagulants: FeSO 4 ·7H 2 O, FeCl 3 ·6H 2 O, Al 2 (SO 4 ) 3 ·18H 2 O, mix of FeCl 3 and Al 2 (SO 4 ) 3 (1:1), (2:1) coagulants, акватикс. During the work, model waste water of JSC «Tyumen Battery Plant» was prepared and the most effective combinations of coagulant-flocculant were selected for extraction of suspended, colloidal particles and lead ions from waste water. Optimal doses are determined for all reagents. method of dynamic sorption on КФГМ-7 sorbent is used for additional treatment of waste water from lead ions. The greatest effect was obtained by coagulation using FeSO _ 4 as a coagulant at an optimal dose of 150 mg/L by adding Flopam 4125 (2mg/L). Water turbidity was 4-5 EmF. In dynamic sorption, the concentration of lead ions when Na 2 O · mSiO 2 · nH 2 O (liquid glass) with coagulant FeSO 4 was used as a floc- culant was 0.01mg/l, which is significantly less than the maximum permissible concentrations of lead in the waste water entering the discharge. The results of the study can be used in the technology of processing used
