In combination with the flocculant, bentonite is highly effective, with a dose of 100 mg / dm3 of the adsorbent and 4 mg / dm3 of flocculant is optimal for calcium and sodium bentonites; the content of resin substances is reduced to 15 and 20 mg / dm3, respectively. A new model of aeration tank is proposed, which allows to reduce air flow and improve the quality of biological treatment. According to research results, the addition of biologically active impurities in the amount of 0.05 mg / kg to the digestible mixture of solid industrial waste increases the final biogas output from 053 dm3 to 0.75 dm3, and the duration of the fermentation process decreases from 20 to 18 days The proposed mathematical model of the process, based on the equation of the material balance of the periodic reactor, which is a laboratory installation. The decomposition reaction of phosphorus proceeds in two stages: the first is the diffusion of acid ions to the surface of particles of natural phosphate; arc - the interaction of natural phosphates with acid. The reactions take place simultaneously and their flow to the degree of decomposition loses. A technological scheme for the production of biogas and complex fertilizers on the basis of solid industrial waste, in which the use of biologically active impurities, as activators of the fermentation process, is developed. The technological scheme of biological wastewater treatment with the use of a combined aerotank tank for the left-bank water treatment plants of Kamyan'skoye is developed, which increases the efficiency of sewage treatment by 30%.
