【 摘 要 】

The present study treats on cleaning wastewater originated from industrial buildings using sorption materials. As sorption materials for the recovery of heavy metal ions, industry wastes were used: threshing millet, cotton fiber, chitosan. The basic sorption characteristics such as purification efficiency, sorption capacity, specific surface and sorption capacity on water were considered. Conditions and modes of heat treatment of sorption materials (temperature and time) are described. A combined use of materials in the form of a layer-by-layer filter and granules is proposed. The efficiency of cleaning materials is 93 to 99.9%, the sorption capacity is from 6.9 to 50 mg/g.
