Abstract:
The quality parameters of the combined wastewater from the cider processing of Yitian Juice (Shanxi) Co., Ltd. are: CODCr ≤4 300 mg/L,BOD 5 ≤2 200 mg/L,SS≤1 500 mg/L,pH 4.5-10,temperature 30-40 ℃. The wastewater is treated bya process ofhydrolytic acidification-biological contact oxidation-sand filtration. The results ofthe operation showthe qualityparameters ofthe effluent water after the treatment are as follows: CODCr 115 mg/L, BOD 5 22 mg/L,SS 58 mg/L,pH 6-8,indicating that the quality of the effluent water meets the requirements of the standard ofclass 2 in Integrated Wastewater Discharge Standard (GB8978—1996).
