食品工业原料广泛，制品种类繁多，排出废水的水量、水质差异很大。但总体来说食品废水中主要污染物有

（1）漂浮在废水中固体物质，如菜叶、果皮、碎肉、禽羽等

（2）悬浮在废水中的物质有油脂、蛋白质、淀粉、胶体物质等

（3）溶解在废水中的酸、碱、盐、糖类等

（4）原料夹带的泥砂及其他有机物等

（5）致命病菌等

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

The food industry has a wide range of raw materials and various kinds of products. The water quantity and water quality are very different. But in general, the main pollutants in food waste water are

(1) solid material floating in waste water, such as vegetable leaves, peel, crushed meat, and poultry, etc

(2) substances suspended in waste water have grease, protein, starch, colloidal substances, etc

(3) acid, alkali, salt and sugar dissolved in wastewater

(4) mud sand and other organic materials of the raw material

(5) deadly germs, etc

Project overview: the main business of a group is related to feed production, food processing, breeding of livestock and poultry and other industries. The annual feed production capacity of the group is over 11 million tons, and the daily slaughter of poultry is more than 2.3 million, and the annual production of livestock and poultry can be more than 100 million. The slaughter of sewage is mainly from the effluent of flushing, washing, slaughtering and other plant floor rinsing, ironing, cuting, cutting, processing and washing of oil.

The water 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, visceral sundry, undigested food, fecal sewage, such as high content of suspended solids.

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

Process flow

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

The acidification treatment is used to convert large molecular organic matter into low molecular organic matter through anaerobic bacteria. After the hydrolyzed acidification pond was released into the contact oxidation pond for biochemical reaction, then it entered the sedimentation tank and the water was filtered and disinfected to meet the standard discharge

Jining day pass is a set of water treatment equipment production and sales of the company, the company has sophisticated technology talented person, has a high quality work team, can provide customers with perfect after-sales service in a timely manner. My company main products: water treatment equipment, sewage treatment equipment, wastewater treatment, industrial wastewater, agricultural wastewater, rain water purification equipment, hospital sewage equipment, steel plant waste water equipment, slaughterhouse wastewater treatment equipment, food factory waste water treatment equipment and other equipment, can professional custom according to the water treatment equipment.
