文档介绍：某屠宰场废水处理工艺设计
摘要
本设计是黑龙江省某屠宰场废水处理工艺设计,采用水解酸化— SBR法处理,出水水质达到国家一级排放标准,废水处理后要求达到:CODCr≤80mg/L, BOD5≤30mg/L,SS≤60mg/L,pH=-,植物油≤15mg/L,NH3-N≤15mg/L,大肠杆菌≤5000个/L。屠宰业是我国出口创汇和保障供给的支柱产业之一,屠宰废水来自牧畜、禽类、鱼类宰杀加工,是我国最大的有机污染源之一。而我国很多屠宰厂尚没设置废水处理装置或对排放的废水进行综合利用,因而污染物质尤其是高浓度的有机物给水环境造成了极大的污染,屠宰废水的污染已不容忽视。本设计就是针对某屠宰废水设计了一套工艺,水解酸化—SBR法,该工艺处理完的水完全达到国家一级排放标准,而且处理成本低廉,管理方便的特点。

Abstract
The design is a shambles wastewater treatment process design in Heilongjiang Province, acid hydrolysis — SBR, effluent quality to a national emission standards for the treatment of wastewater:CODCr≤80mg/L, BOD5≤30mg/L, SS≤60m/L, pH=-. vegetable oil less than 15mg/L, NH3-N≤15mg/L, E coli≤5000. Slaughtering industry is guaranteed supply of foreign exchange and pillar in from slaughtering livestock breeding, poultry, fish slaughter processing, is the country's largest sources anic one. In China, many plants have not been slaughtered install a waste water treatment plant or wastewater posite,Thus polluting substances is particularly high concentration anic water caused severe environmental pollution. Slaughter house wastewater pollution has not to be ignored. The design is meant to address a slaughterhouse wastewater design a process, Acid hydrolysis — SBR,End of the Process of water to achieve a national emission standards, but also with the low cost, easy management features.
Key words: Slaughterhouse wastewater; SBRpool; National Standards
