The characteristics of the waste water are as follows:

The main components are blood, oil, feces, visceral debris and inorganic salts.

(1) High COD, generally above 2000mg/L;

(2) High SS

(3) High NH₃-N, animal manure, animal protein contains a large amount of ammonia nitrogen;

(4) High oil concentration.

Slaughter waste water treatment technology

In the slaughter waste water treatment process, aerobic treatment, anaerobic treatment and chemical flocculation treatment have their own advantages and disadvantages. Generally, when processing lower concentration (CODcr≤1000mg/L) of slaughter waste water, biological treatment can be directly used. Under the condition of ensuring the treatment effect, the processing flow is shortened and the capital construction cost is saved;

When dealing with higher concentrations (CODcr > 1000 mg / L) of slaughter waste water, the combined use of several processes ensures that waste water treatment could up to standard. For example, the hydrolyzed aerobic biological treatment process engineering investment is only 70% comparison the same-scale activated sludge process, the land occupation is reduced by 20%, and the treatment cost is reduced by 42%. The optimized combination of treatment processes is conducive to various processes to avoid weaknesses and ensure the quality of the effluent.
