Parameters of optimized system of technological process of waste water disinfection of livestock enterprises in integrated physico-chemical effects

The development of livestock production is one of the main factors in ensuring food security of most states. Unfortunately, the safe use of livestock wastes is impossible without their decontamination. In this paper the parameters of the method of disinfection of the liquid fraction of livestock wastes with the complex physicochemical effect of a rotating electromagnetic field with ferromagnetic rods moving inside it and active chlorine are optimized. The result of optimization is a reduction in the electric energy consumption of the process while meeting the requirements for epidemiological safety. The parameters of the optimized system have the following definitions: the filling of the working zone of the inductor with ferromagnetic rods ρ = 5.18%; magnetic induction B = 40 mT; ratio of the length of the ferromagnetic rods to their diameter l/d = 25; active chlorine concentration ω = 15.60 mg/l; duration of action t = 2.81 s; while the specific electricity consumption is N_u = 3.09 W⋅c/ml, and the epidemiological safety indicators do not exceed the permissible limits of normative documents.
