Meat processing wastewater treatment

Luoyang Company, located in the western industrial zone of Luoyang City, is a large-scale modern listed company integrating the production and marketing of meat products, food packaging films and related products. It is the main meat processing and meat product production enterprise in China. At present, it has become the largest ham sausage production base and food packaging base in China, with an annual design and production of 100000 tons of meat products.

The company was founded in 1958, and has not been equipped with sewage treatment facilities. According to the document of Henan Environmental Protection Bureau Yuhuan control (1996) No. 54, the company's production wastewater treatment project belongs to the treatment project within a time limit, and it is required to reach the discharge standard by the end of 1999.

Technological process

The treatment project adopts hydrolysis acidification biological contact oxidation air flotation process

Engineering characteristics

(1) through the hydrolysis and acidification of the hydrolysis regulating tank, the biodegradability of the sewage is improved, which is conducive to the subsequent biological treatment;

(2) the hydrolysis regulating tank digests and degrades part of the excess sludge and reduces the sludge quantity;

(3) the biological contact oxidation tank is built on the hydrolysis regulating tank, which reduces the occupied area, and the upper space of the hydrolysis regulating tank is utilized, which reduces the investment. The occupied area of 1m3 water treatment is only 0.3m2;

(4) the treatment effect is good, no sludge bulking occurs, and the effluent quality is better than the national standard.
