It is about problems in purification of industrial wastewater and utilization of solid wastes as raw materials resources which are needed a scientific way of studying. The way of generation composite granular sorbent filter material on the basis of man-caused and minerals, using which is allowed to increase ecological safety food industry enterprise because of using waste conversion technique, as well modern methods of sorption purification , is offered and described here. A detailed chemical composition, which consists of tobacco dust and natural component as bentonitic clay, using for getting granular sorbent filter material, is studied. They studied real industrial wastewater to make researches for the detection residual impurity in the filtrate using composite granular sorbent filter material.

A new practical application of waste biological treatment of municipal wastewater activated sludge as a raw material for the composite-selective adsorbent is presented for the first time. Composite-sorbent contains up to 85% of the surplus activated sludge, and the rest-diatomit partlandtsement. It is shown that the adsorption capacity and selectivity of the resulting composite material is stabilized after electrochemical activation. The implementation preliminary purification step of waste water from ions of heavy metals allows to clean water to the regulatory requirements at minimum cost.

The article is about one of the possible method of the spent sorbent utilization as a recultivated addition for oily soil liquidation. The main sources of the oil pollution are mentioned. It is suggested to use the spent selective sorbent as addition for oil liquidation, which is consisted of 70% of the spent active ooze and 30% of mineral component. The physicochemical properties of the spent sorbent based on the excess active ooze are studied. The average data of nitrogen, phosphorus, potassium containing is mentioned. It is experimentally proved that oily soil, which contains a great amount of organic matter, decreases the toxicity of heavy metals, and plants can delete them. Brassica juncea, which belongs to mustard family, was chosen for the laboratory research as an effective accumulator of the heavy metals ions. The heavy metal ions are absorbed during the process of the Brassica juncea seed sprouting and then they are moved to the top of the plant that is why at the end of the basic process of vegetation the toxic polluted biomass is reduced and utilized. There are recommendations for the preliminary preparation of the spent sorbent before using it as the recultivated addition in the oily soil.
