Chapter 1
The waste water from pig farm is formed by the washing of fecal water in the process of the pig production, and the displacement is large. The waste water consists mainly of pig urine, partial residue or whole pig manure, feed residue and pig shaper. Its characteristics are related to the structure of the piggery, the method of cleaning the manure, the nutrition of pig feed, digestion, production management and water use. A pig farm has an annual deposit of 10,000 pigs and a daily discharge of about 150 m3. If the waste water is discharged directly into the water, the water will be eutrophicated. In order to protect the environment, it can be used to recycle pig manure.
Chapter ii design data
2.1 water
According to the data provided, the discharge of sewage from pig farms is 150m3 / d.
2.2 water quality
According to the information provided, the design parameters are as follows:
CODcr: 20000mg/L
BOD5:10000mg/L
SS: 8000mg/L
PH: 6.5 to 8.0
2.3 discharge standard
After treatment, the wastewater has been processed to meet the first-class standards of the Peoples Republic of China (gb8978-1996) :
CODcr is less than or less than 100 m g/L
BOD5 is less than 30 m g/L
SS is equal to 70 m g over L
PH: 6-9
The scheme design of the wastewater treatment project of pig farm is designed, which is divided into the two parts of the anaerobic section and the partial parts of the oxygen and oxygen in the forebody of the whole process. The design data of the anaerobic section is listed
