Annotation. The main goal when creating typical waste water of JSC “Tyumen Battery Plant” is to bring the composition as close as possible to real waste water. The aim of the work is to study the process of sorption post-treatment when working with different types and concentrations of coagulants and flocculants, to select the most effective coagulants and flocculants and their doses, which give maximum effect of sorption post-treatment from colloidal-dispersed impurities and lead ions. For work the following coagulants were selected: FeSO 4 ·7H 2 O; FeCl 3 and Al 2 (SO 4 ) 3 in various relations (1:1), (2:1), (1:2); Flocculants: Flopam FO 4125 SH, Flopam FO 4440 SH, Flopam FO 4115 SSH; Praestol 2531 TR, Praestol 650 TR, Na 2 O · mSiO 2 · nH 2 O sodium metasilicate (Liquid glass). In process of operation method of dynamic sorption on sorbent of KΦГM-7 is used for additional purification of waste water from lead ions. Based on the data obtained, recommendations can be made to intensify the subsequent treatment of waste water from battery production using the following reagents: FeCl 3 (83mg/l) + Al 2 (SO4) 3 (42mg/l) and Liquid glass (1mg/l); FeSO 4 7H 2 O (150g/L) и Flopam FO 4115 SSH (1mg/L); FeSO 4 · 7H 2 O (150 mg/L) and liquid glass (1 ml).
