Slaughterhouse wastewater treatment flocculant selection Polyacrylamide and polyaluminum chloride slaughterhouse wastewater treatment Poly aluminum chloride and polyacrylamide flocculant to deal with the effect is obvious, from the nature of the slaughterhouse, with other flocculation Agents can not meet the processing requirements. Slaughterhouse wastewater is a highly biodegradable high-concentration organic wastewater with a BOD5 and CODcr ratio of about 0.5. For such easily degradable organic wastewater, many slaughterhouses currently use membrane treatment technology to treat such high concentration organic wastewater. The characteristics of slaughterhouse wastewater are as follows: 1.Water quality and water quantity change greatly. The slaughtering volume and production wastewater volume vary greatly with season, day and time. 2.High organic content, good biodegradability and high content of suspended solids Large amounts of blood, grease, hairs, meat pieces, visceral debris, undigested food, manure and other contaminants), with repulsive blood red and blood smell; 3 poultry slaughtering wastewater contains more hair.
