Use and improvement of the sorption method for cleaning drainage runoff of reclamation systems

Technologies and methods of directed regulation of the quality composition of drainage runoff in the hydro-reclamation systems of the Non-Chernozem zone of Russia may be different depending on the volume and chemical composition of the runoff and environmental requirements for water quality for reuse and safe disposal. One of the most promising ways to improve the quality of drainage water is sorption treatment of runoff, the effectiveness of which is determined by the design of the sorption-filter unit, the selection of sorption material for the filter based on the flow rate of drainage runoff and the degree of its contamination. The layout, placement and design features of sorption-filter cleaning units are presented, the efficiency indicators of the use of a number of sorbents for cleaning drainage runoff, the main impurities removed and the degree of purification are given. An engineering solution is proposed to increase the efficiency of sorption-filtering facilities by regulating the uniformity of the interaction of drainage water with the entire mass of the sorption-filtering load by equalizing the dynamic pressure of the drainage water flow on the filter material.
