In this paper, shows the results of studies of the effect sludge drying beds aeration stations in Almaty, Kazakhstan on the surrounding area. The results showed that the groundwater of surrounding areas sludge drying beds aeration stations Almaty contain elevated concentrations of iron, phosphate, magnesium, zinc. And also, the water of the Big Almaty River after sludge drying beds has some elevated concentrations of heavy metals, such as iron and zinc than the water of the Big Almaty River to sludge drying beds. In general, the sewage sludge that is stored on the sludge beds turns them into a hotbed of bacteriological and toxicological hazard. This article aims to identify environmental problems of handling and disposal of sewage sludge in Almaty.
