To the question of electrocoagulation purification of wastewater containing emulsified oil

The results of studies of electrocoagulation pro-cess using asymmetric current wastewater contain-ing emulsified oil products, which are produced at the enterprises of tractor and agricultural machinery are given. To identify factors that influence the pro-cess of electric treatment and to obtain mathemati-cal models, the study of the technological process of clearing oily waste water was conducted using the planning method Box-Hunter experiment. It was found out that the use of asymmetric current con-tributes to the effective dissolution of the anode due to the destruction of the polarization of the oil film by a pulse of negative polarity, which will ensure the stability of the process of processing of oily waste with a high cleaning effect. For graphic inter-pretations in the form of surfaces and the regulatory process electrotreatment drains considering tech-nical and economic indicators, calculations have been made in the ‘Scilab’ program. The data on the properties and composition of the sludge produced in the purification process were obtained by differ-ential thermal analysis instrument NETZSCH STA 449 F1 and X-ray analysis method diffractometer D8-ADVANCE, the German company «Bruker-AXS». The experimental results showed that it was possible to use precipitation as an additive in the production of wood-concrete mixtures, gypsum, concrete, mortar. The introduction of sludge addi-tive in an amount from 2.0 to 2.5 % significantly reduced the average density (bulk density) gypsum, wherein the porosity of the product increased and consequently their insulating properties were im-proved. Solving urgent problems of oily waste water processing and disposal of sediments enables im-plementing a set of measures to reduce waste en-terprises tractor and agricultural machinery for pre-venting environmental pollution.
