Improvement of the technology of local wastewater treatment of the meat plant

An improved technology for the local treatment of industrial wastewater a meat processing plant is proposed intensification cleaning processes and an increase in efficiency according to indicators: HSC, SPAR, phosphates, ammonium nitrogen, fats, obtaining purified water accordance with regulatory requirements at discharge into city sewer. According technology, after existing grease trap concentrator pumped reactive flotation using alkaline reagent coagulant - aluminum sulfate, production flakes as result coagulation, removal pollutants from separation phases form sludge sediment quality indicators requirements. The formed during diverted collector taken away, sediments are recommended be dewatered on filter press away. On basis performed experimental studies, it was established that when sulfate used dose 250-300 mg/dm3 pH 7-7.5, effects are: 460-670 mg/dm3; suspended substances 90-95%, content 10-23 SPAR 88%, 0.43-0.08 phosphates 62-65%, phosphate 3.6-5.4 nitrogen 40-42%, 15.3-17.0 mg/dm3. coagulation methods has been developed, implementation which will allow high-quality water, meet drainage system Kharkiv.
