PERFECTION WATER THE SYSTEM FOR CLEANING CONTAINING OIL IN AGRICULTURAL PRODUCTION
It is known that environmental pollution with petroleum products in the operation and maintenance of agricultural machinery causes great environmental damage. There are many methods of purification of oily waters, however, none of the existing individual methods allows to carry out this process with high efficiency, so you should use a combination of cleaning methods, integrated use of which will allow to achieve maximum effect. Consistently implement the pre-cleaning of oily water in the gravitational dynamic settlers, then their final purification, and recycling formed during this concentrated solid and plastic waste is recommended. It is proposed to use a thin layer plate tank-settler as a dynamic gravitational cleaner. The process of separating the multi-phase oil-water emulsion containing solid organic and mineral pollution is studied and optimal design parameters of the device are defined. It is established that the greatest efficiency of cleaning of the multiphase mixture of solid particles in a dynamic tank-settler is achieved when the angle of inclination of the plates is equal to 45 degrees. It is defined that the efficiency of separation of oil from emulsion depends on the distance between the plates, wherein the maximum value of efficiency was reached with the gap of 5 mm. It is established that the use of tank-settler removes solid contaminants with particles larger than 25 microns and separated over a third of oil. In order to achieve the established norms of maximum permissible containing deposits of oil in water it is recommended to use a flotation plant. The use of combined technologies of separating water-oil emulsion mixture is used for cleaning of washing oily water to 2.4 ml/l, which can be disposed of by draining it into the municipal Sewerage system (the allowable oil content in production wastewater to 4 mg/l), which is able to significantly improve ecological safety on objects of oil products supply in agricultural production.
