摘要本次主要是对屠宰废水处理进行设计。屠宰废水主要来自畜牧，鱼类，禽类等宰杀加工，是我国最大的有机污染源之一。废水的危害：屠宰过程中会产生大量的含血污水、动物粪便等杂物，还会散发出一种难闻的气味，还含有大肠菌、粪便链球菌等对人体造成伤害的细菌。这些水体中含有的物质的量容易发生变化而且还含有大量的有机物，如果不处理直接排放将严重污染环境。在查找相关资料的基础上，依据废水的水质水量选择合适的工艺流程。废水先经过格栅、隔油沉淀池、调节池等物理处理构筑物，然后再通过UASB反应池，SBR反应池。最终出水达到《肉类加工工业污染物排放标准》（GB8978-2002）一级标准。选择适宜的工艺流程之后对构筑物进行了设计计算、设备选型，处理站的平面布置和高程布置，并完成了成本估算，经估算吨处理成本为0。5元。84321

Abstract This design project was aim at study the disposal of the slaughter wastewater treatment。 Slaughter wastewater is mainly from animal husbandry, fish, poultry and other slaughter processing, is one of the largest sources of organic pollution in china。 The harm of wastewater: Slaughter process will produce a large number of sewage, animal feces and other debris, but also emit an unpleasant odor, but also contains Escherichia coli, fecal streptococcus and other harmful bacteria on the human body。 The amount of substances contained in these waters is likely to change but also contains a large amount of organic matter, if not treated directly to discharge will seriously pollute the environment 。Firstly the wastewater flow up to some physical treatment structures such as grille, oil separation and sedimentation tank, adjusting pool。 And then, the wastewater is treated by the UASB reactor。 Finally the wastewater reach discharge standard of pollutants for meat processing industry（GB8978-2002）primary standard。 After choosing the appropriate technical process, the following job is the design of structures, the choice of equipment, the layout and elevation layout of the sewage treatment station which with complete the cost estimates,the estimated treatment cost is 1 yuan per ton。

Key words: Slaughter waste water; UASB reactor; SBR reactor
