Abstract

The invention provides a slaughter wastewater flocculating agent which is formed by the following components in parts by weight: 10-20 parts of lignosulphonate-acrylamide copolymer, 2-6 parts of polyphosphorus chloride, 10-15 parts of polysilicate and 3-5 parts of polyferric chloride sulfate. According to the slaughter wastewater flocculating agent, the polysilicate is aluminum polysilicate or iron polysilicate; and the polyphosphorus chloride is polyphosphorus aluminum chloride or polyphosphorus iron chloride.

Description

technical field [0001] The invention belongs to the field of water treatment agents and relates to a flocculant, in particular to a flocculant for slaughter wastewater treatment. Background technique [0002] Slaughter wastewater is a kind of livestock wastewater. It belongs to high-concentration organic wastewater. It is generally reddish brown and has an unpleasant smell. Pollutants exist in water in three forms: solubility, colloid and suspension, and the content of suspended solids is high. , high-concentration organic matter is not easy to degrade, and the treatment is difficult. Slaughter wastewater comes from pen washing, rinsing, slaughter and other workshop floor washing, scalding, dissection, non-staple food processing, oil washing, etc. It has large water volume, uneven drainage, high concentration, many impurities and suspended solids, and can be Good biochemical characteristics. The pretreatment of slaughter wastewater is the key to the effective operation of ...
