Technology And Application Analysis Of Slaughterhouse Waster Water Treatment

Technology and Application Analysis of Slaughterhouse Waster Water Treatment

Slaughtering waste water from the circle bar rinse, rinse, slaughter and other plant floor rinse, hot hair, split, non-staple food processing, washing oil, it has a large amount of water, uneven drainage, Waster Water Treatment high concentrations of impurities and suspended solids, Good biochemical characteristics. In addition, it is the biggest difference with other high concentration of organic wastewater is its high NH3-N concentration (about 120mg / l), so in the process design should take full account of NH3-N on the impact of Waster Water Treatment.

Analysis of Water Quality of Slaughterhouse Wastewater

Slaughtering waste water from the circle bar rinse, rinse, slaughter and other plant floor rinse, hot hair, split, non-staple food processing, washing oil, it has a large amount of water, Waster Water Treatment uneven drainage, high concentrations of impurities and suspended solids, Good biochemical characteristics. In addition, it is the biggest difference with other high concentration of organic wastewater is its high NH3-N concentration (about 120mg / l), so in the process design should take full account of NH3-N on the impact of Waster Water Treatment.

Pretreatment of Slaughterhouse Wastewater

Pretreatment of slaughtering wastewater is the key to the effective operation of the entire system. Slaughtering waste water in the solid suspended solids (SS) up to 1000mg / l, the suspended matter is perishable organic matter, must be timely interception, on the one hand to prevent the subsequent pipeline equipment blockage, on the other hand immediate clean up to avoid suspended solids organic matter Into the wastewater and become soluble organic matter, Waster Water Treatment resulting in wastewater CODCr, BOD5 concentration increased. Slaughter of waste water includes a large number of pig manure, unsweetened feed fence washing water and general slaughter of two major categories of waste water.

The rinse water is pretreated by a septic tank and then merged with the general slaughterhouse wastewater to enter the Waster Water Treatment station. The pig manure and the undigested feed deposited in the septic tank are extracted and dried by a squeeze solid-liquid separator Moisture content of up to 70%) as a fish feed.

There are two main methods of pretreatment of slaughtering wastewater: air floatation and sieving (filter pore size 1 ~ 5mm). Air flotation is mainly used in the treatment station with small waste water. The main drawback is that the equipment is complicated, difficult to manage and the running cost High and poor hygienic conditions. Screening is mainly applied to the pretreatment of slaughtering wastewater with large waste water treatment, Waster Water Treatment convenient management and stable operation.

Also in the filter before the need to set the fishing pool, rough grid (50 × 5mm), coarse grille (20mm) and other protective measures.
