食品工业的内容极其复杂，包括制糖、酿造、肉类、乳品加工等生产过程，所排出的废水都含有机物，具有强的耗氧性，且有大量悬浮物随废水排出。动物性食品加工排出的废水中还含有动物排泄物、血液、皮毛、油脂等，并可能含有病菌，因此耗氧量很高，比植物性食品加工排放的废水的污染性高得多

工程概述：某集团主营业务涉及饲料生产、食品加工、种畜禽繁育等产业。集团年饲料生产能力1100多万吨，日宰杀家禽能力230多万只，年可生产畜禽种苗1亿多只。屠宰污水主要来自于圈栏冲洗、淋洗、屠宰及其它厂房地坪冲洗、烫毛、剖解、副食加工、洗油等工序所产生的污水，

水质特点

1、屠宰污水一般呈红褐色，有难闻的腥臭味,其中含有大量的血污、油脂质、毛、肉屑、骨屑、内脏杂物、未消化的食物、粪便等污物，固体悬浮物含量高。

2、屠宰污水有机物含量高，可生化性好其中高浓度有机质不易降解，处理难度较大，宰污水中的营养物主要是氮、磷，其中氮主要以有机物或铵盐形式存在，而磷主要以磷酸盐的形式存在。

 工艺流程

 来自屠宰场的污水经格栅（网）去除污水中的毛、皮、浮渣和大颗粒悬浮物后自流入隔油池，去除大部分油脂和泥砂后进入调节池，经调节池调节水质水量后，并保证后续处理设施的正常运行。经过调节池的水经泵提升至平流式气浮沉淀一体机。先期去除水中悬浮物（ss），去除率达90%以上，出水进入一体化污水处理设备，一体化污水处理设备由（水解酸化池、二级接触氧化池、沉淀池组成），污水在水解酸化池

进行酸化处理，通过厌氧菌将大分子有机物转化成低分子有机物；经水解酸化池流入接触氧化池进行生化反应后再进入沉淀池，出水经过滤消毒达标排放

Thecontent of the food industry is extremely complex, including sugar, brewing,meat, dairy products processing, such as the production process, all thewastewater containing organic matter, has strong oxygen consumption, and thereare a large number of suspended matter with waste water discharge. Animal foodsalso contain animal waste in processing the wastewater, blood, fur, grease,etc., and may contain bugs, so the oxygen consumption is very high, than foodprocessing plant emissions of waste water pollution is much higher

Projectoverview: the main business of a group is related to feed production, foodprocessing, breeding of livestock and poultry and other industries. The annualfeed production capacity of the group is over 11 million tons, and the dailyslaughter of poultry is more than 2.3 million, and the annual production of livestockand poultry can be more than 100 million. The slaughter of sewage is mainlyfrom the effluent of flushing, washing, slaughtering and other plant floorrinsing, ironing, cuting, cutting, processing and washing of oil.

Thewater quality characteristics

1,slaughter wastewater generally is reddish brown, has the unpleasant stench,which contains a lot of blood, fat mass, wool, meat scraps, skeletal, visceralsundry, undigested food, fecal sewage, such as high content of suspendedsolids.

2,slaughter wastewater organic matter content is high, can good biochemical withhigh concentration of organic matter is not easy to degrade, processing isdifficult, the nutrients in slaughter wastewater is mainly nitrogen,phosphorus, nitrogen mainly exists in the form of organic matter or ammoniumsalt, and phosphorus mainly exists in the form of phosphate.

Processflow

Fromslaughterhouse wastewater by grid (mesh), remove the wool and leather in thesewage, scum and since into the separation tank, after the big particlessuspended after removing most of the oil sand and mud into the basin, afterregulating pool water, and ensure the normal operation of the subsequenttreatment facilities. The water through the regulating pool is pumped up to theflat flow type air floating precipitator. Early removal of suspended solids(ss) in water, the removal rate of more than 90%, the water into the integratedwastewater treatment equipment, the integration of sewage treatment equipmentby (hydrolysis acidification pool, secondary contact oxidation pool,sedimentation tank), sewage in the hydrolysis acidification pool

Theacidification treatment is used to convert large molecular organic matter intolow molecular organic matter through anaerobic bacteria. After the hydrolyzedacidification pond was released into the contact oxidation pond for biochemicalreaction, then it entered the sedimentation tank and the water was filtered anddisinfected to meet the standard discharge
