肉类加工 屠宰厂废水处理工程案例

Case study of meat processing wastewater treatment

（一）   工程概况

某食品公司有屠宰车间、熟肉制品加工车间、冷加工车间以及其他辅助设施等组成。该公司生产规模为年屠宰活猪20万头，加工熟肉制品20万头/年，按照一年261天工作日计算，平均每日屠宰加工活猪768头。

项目设计废水处理规模840m3/d，工程于2013年完工，2014年6月开始调试,2015年验收。

（二）   屠宰场废水处理工艺

1 生产工艺及水质

该公司废水属中等浓度有机废水，水量大，废水中含有大量的血污、毛皮、碎肉、内脏杂物等，不含重金属及有毒化学物质，废水中富含蛋白质及油脂。

(I) project overview

A food company has a slaughtering workshop, cooked meat products processing workshop, cold processing workshop and other auxiliary facilities. The company produces 200,000 live pigs and 200,000 processed meat products in a year. The average daily slaughtering and processing of live pigs is 768, according to the annual average of 261 days a year.

The project design wastewater treatment scale is 840m cubed/d. The project was completed in 2013 and began to be debugged in June 2014.

(2) processing technology

1 production process and water quality

The company belongs to the medium concentration organic wastewater, wastewater quantity is big, the wastewater contains large amounts of bloody, fur, ground meat, visceral sundry etc., do not contain heavy metals and toxic chemicals, in waste water is rich in protein and fat.

2 处理工艺

本工程出水水质要求较高，为了强化有机污染物去除效果，采用了厌氧-好氧组合工艺，其中厌氧采用水解酸化发，好氧采用接触氧化法。由于原水中悬浮物和油类较多，为了降低生物处理的负荷，在流程前端设置隔油沉淀。悬浮物主要在初沉和水解酸化单元中得到去除。为了保证出水水质，生物处理后设置了纤维球和生物炭两级过滤，最终实现达标排放。

3 工艺流程

本工程的工艺流程可分为预处理、厌氧-好氧生物处理和深度处理三部分。

2 treatment process

This project water quality request is higher, in order to strengthen the organic pollutants removal efficiency, used the combination of anaerobic - aerobic process, including anaerobic using hydrolytic acidification, aerobic contact oxidation method. In order to reduce the load of biological treatment, oil precipitation is set up at the front end of the process because of the high suspension and oil in the original water. Suspended objects are mainly removed in the initial sedimentation and hydrolytic acid units. In order to ensure the water quality, the biological treatment, the fiber ball and biochar filter are set up, and finally meet the standard emission.

3 process flow

The process flow of this project can be divided into three parts: pretreatment, anaerobic - aerobic biological treatment and depth treatment.

三  工程设计

1 平面设计

本项目占地面积2000㎡，长50m，宽40m，南北向布置。

2 高程设计

废水处理厂区自然地坪高程约32~32.2m，根据厂区总体设计要求，室外自然地坪高程为33.1m，回填土厚度约1m。设计室内地坪为±0.00，对应高程33.40m。

Three engineering design

1 graphic design

The project covers an area of 2000 ㎡, 50 m long, 40 m wide, north and south to decorate.

2 elevation design

The natural floor elevation of the waste water treatment plant is about 32~32.2 m. According to the overall design requirements of the plant, the outdoor natural floor elevation is 33.1 m, and the backfill soil is about 1m. The design indoor floor is plus or minus 0.00, corresponding to absolute elevation 33.40m.
