【 摘 要 】

The paper demonstrates that car service stations and their wastewater heavily pollute the environment. The research shows that this wastewater can be cost-effectively purified up to the standards applied to circulating water supply of similar enterprises. Keywords: circulating water supply, maximum allowable concentration (MAC), reagent sedimentation, electroflotocoagulation, purification technology. The analysis of the obtained results shows that the water clarification effect was very high. Comparing two kinds of filtering loads shows that vermiculite is more preferable and effective because its purification effect is more apparent than that of brucite. Besides, vermiculite partially removes the smell of the wastewater drainage. In addition, the use of AA allows one to significantly reduce the salt load on reservoirs and watercourses and keep the pH value within the required MAC.
