???? Farm pig farm sewage treatment equipment aquaculture wastewa

Farm pig farm sewage treatment equipment aquaculture wastewater treatment equipment performance is stable and reliable, good treatment effect, investment, less land occupation, easy maintenance and other advanes.Equipment buried below the surface, of equipment above the surface can be used as green or other land,????, without the need for housing and heating, heat preservation, equipped with automatic electrical control system and alarm system: without manual management, automatic operation, efficient biochemical treatment as the core, set of biochemical treatment, sedimentation, filtration, disinfection unit processing as a whole, treatment of water quality stability, using international advanced biological treatment processes,ugg japan, the removal of BOD5, COD, NH3-N set in a body.Composition: (1) the primary settling tank for vertical flow sedimentation tank.Sewage water in the sedimentation tank upward flow rate of 0.2-0.3 mm / sec, the deposited sludge using air to the sludge tank.(2) the contact oxidation pool: primary settling after the water is flowing to the contact tank for biochemical treatment, contacting pool is divided into three levels, the total duration of stay for 4-6 hours, filler for novel trapezoidal packing, easy conjunctiva, no blockage, filler surface area is 160m2/m3,????? ????, contacting pool gas water ratio is about 12:1 (3) after biochemical cultivation sewage flows into the two tank, two sink the pond of two vertical flow sedimentation tank in parallel operation, increase the flow rate was 0.1-0.15 mm / sec, mud by air to the sludge tank.(4) the pool disinfection and disinfection pool according to the standards for 30 minutes, disinfection using chlorine tablets dissolved solid contact disinfection methods,?????? ??, disinfection device according to the water quantity in the constantly changing dosage, achieve multiple dosing less water, less water dosing purposes.Other disinfection device can be made (5): the primary settling tank sludge tank, two sink the pond sludge are all with air to breeding wastewater treatment plant sludge pool aerobic digestion of sludge supernatant, pool returned to contact oxidation pool for processing, aquaculture wastewater digested sludge rarely,mbt???.Related articles: http://forum.potopisnik.si/showthrea...1358#post51358 http://www.eurodrivers.ca/forums/sho...456#post272456 http://www.intilaaqah.org/forums/sho...617#post171617
