STUDY TECHNOLOGY OF EXTRACTING SUSPENDED SOLIDS FROM MUNICIPAL AND INDUSTRIAL WASTEWATER BY COAGULATION

The urgency of solving the problem purification municipal and industrial wastewater is colloidal degree of dispersion is shown. The regularities coagulation process of wastewater inorganic reagents is obtained. The concentration of suspended solids and phosphates wines before and after coagulation are determined. Found that using chlorides of iron and aluminum is possible to achieve simultaneous removal of deep suspended solids wines and phosphates from municipal wastewater. The optimal dose for each coagulant is defined. For the treatment municipal effluents is optimal AlCl3 dose 60 mg/dm3 at process duration 30 minutes, industrial wastewater – FeCl3 dose 60 mg/dm3 and contact time 30 minutes. It is recommended to use coagulants intensify the process clarification in wastewater treatment technologies.
