屠宰废水预处理后的SBR工艺处理工程

The SBR Process Treatment Station after Slaughtering Wastewater Pretreatment

于2006年7～10月，在广西贵港南山食品有限公司设计屠宰废水预处理后的SBR工艺处理工程。处理工程用三道隔网和隔油沉渣池预先去除毛皮等固体杂物以及油脂等细小悬浮物，然后经调节池进入SBR工艺处理废水。预处理能够容易地去除废水中的油脂，COD、BODs、SS的最高去除率达47．0％，48．3％，62．0％。工程处理废水的最佳曝气时间7h，COD、BOD5、NH3-N去除率分别是95．3％，97．5％，97．3％，出水水质达到国家一级排放标准。工程处理屠宰废水的工艺流程简单，操作运行稳定、投资少，对水量和水质的变化有较强的抗冲击能力，特别适宜废水排放量在500m^3／d以下的小型屠宰厂推广应用。

From July to October 2006, the SBR process treatment station after Slaughtering wastewater pretreatment have been designed in Guangxi Guigang Nanshan Food Co., Ltd. First,treatment station employed three grids and grease traps sediment pool to advancely remove debris,fur and other solid fats such as small suspended solids of Slaughtering wastewater. Then, Slaughtering Wastewater will flow into adjustment pool and SBR wastewater treatment. Pretreatment can easily remove the grease in wastewater. The highest removal rate of COD, BODs and SS reached 47. 0%, 48. 3%, 62. 0%, respectively. The best aeration time of Wastewater treatment station is 7 hours, which the removal rates of COD,BOD5,NH3-N were 95. % and 97. 5%, 97. 3%, respectively. After SBR process treatment, the water level indicators meet the state emission standards. The advantages of slaughtering process of waste water treatment station is simple, stable operation and low investment. The slaughtering process strongly resistant to the quantity and quality changes of water, which is particularly suitable for small slaughtering plant with less than 500m^3/d waste Water emissions.
