屠宰場污水一級處理就是將廢水中的毛、皮以及各種浮渣還有大顆粒懸浮物,比較終進入到隔油池。
這個步驟主要目的就是將其中的油脂與廢水中的泥砂去除,然后進入調節池,調節池的作用就是為了為保證后續處理能夠正常運行得到穩定出水水質,不僅如此還能起到調節水量和均化水質的作用。
經過調節池的水會被壓力泵提升到浮沉淀一體機。去除率能達到百分之九十,得到的水質會進入到廢水處理設備,一體化廢水處理設備主要包括水解酸化池以及二級接觸氧化池還有沉淀池組成,屠宰廢水在水解酸化池進行酸化處理,全部的大分子有機物會被轉化為低分子有機物,經過廢水生物處理新技術水解的廢水進行到比較終的沉淀池,池出水經過濾消毒達標排放。
The primary treatment of slaughterhouse wastewater is to put the wool, skin, various scum and large particle suspended solids in the wastewater into the oil separation tank.
The main purpose of this step is to remove the grease and sludge in the wastewater, and then enter the regulating tank. The function of the regulating tank is to ensure the normal operation of subsequent treatment and obtain stable effluent quality. In addition, it can also regulate the water volume and homogenize the water quality.
The water passing through the regulating tank will be lifted to the integrated floating sedimentation machine by the pressure pump. The removal rate can reach 90%, and the obtained water quality will enter the wastewater treatment equipment. The integrated wastewater treatment equipment mainly consists of hydrolysis acidification tank, secondary contact oxidation tank and sedimentation tank. The slaughterhouse wastewater will be acidified in the hydrolysis acidification tank, and all the major organic matter will be transformed into low molecular organic matter. The wastewater hydrolyzed by the new wastewater biological treatment technology will go to the final sedimentation tank, The effluent from the tank is discharged after being filtered and disinfected to meet the standard.
