水解酸化＋ SBR工艺处理屠宰废水实例

采用“水解酸化＋ SBR”工艺对某企业屠宰过程中产生的废水进行处理.运行结果表明：当废水进水COD、BOD5、SS、NH3-N、动植物油浓度分别为1 350mg/L、720 mg/L、780 mg/L、55 mg/L、150 mg/L时,出水浓度分别为55 mg/L、15 mg/L、25 mg/L、10 mg/L,8 mg/L,去除率分别达到95.9％、97.9％、96.8％、81.8％、94.7％,出水水质达到《肉类加工工业水污染物排放标准》（GB 13457-92）一级排放标准要求.

Hydrolytic acidification + SBR slaughterhouse wastewater treatment process

The ＂hydrolytic acidification ＋ SBR＂ process is used in processing slaughter wastewater. The results showed that when the wastewater influent COD, BOD5, SS, NH3- N, the animal and vegetable oils concentra- tions were 1350 mg/L, 720 mg/L, 780mg/L, 55 mg/L, 150 mg/L respectively. The effluent concentrations were 55 mg/L, 15 mg/L, 25 mg/L, 10 mg/L, 8 mg/L, and the removal rate reached 95.9% , 97.9% , 96. 8% , 81.8% , 94.7%. The effluent quality meets Grade 1 emission standard of ＂Discharge Standard of Water Pollutants for Meat Packing Industry＂（GB 13457-92）.
