Abstract

The invention discloses a device and a method for treating meat processing waste water, and belongs to the technical field of waste water treatment. A filter device, a water collecting well, an oil separation sand setting tank, an adjusting tank, a floatation tank, an anaerobic hydrolysis tank, a contact oxidation tank, a folded plate reaction tank, a secondary sedimentation tank and a disinfection tank of the device are connected in sequence; the secondary sedimentation tank is connected with the anaerobic hydrolysis tank; sludge discharge outlets of the oil separation sand setting tank, thefloatation tank and the secondary sedimentation tank are connected with a sludge thickening tank; the sludge thickening tank is connected with the adjusting tank; the sludge thickening tank is furtherconnected with a sludge tempering tank; the sludge tempering tank is connected with a sludge dehydration device; and the sludge dehydration device is connected with the adjusting tank. According to the device and the method disclosed by the invention, treated waste water can reach the primary standard of ''discharge standard of water pollutants for meat packing industry'', the treatment effect isstable, and the threat of meat processing waste water on the environment is relieved effectively.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and more specifically relates to a meat processing wastewater treatment device and method. Background technique [0002] Meat processing wastewater has the following characteristics: (1) The water quality and quantity vary greatly. Meat processing enterprises mostly work in one shift, with large daytime flow and high water concentration, and small nighttime flow and low water concentration, so adjustment and homogenization must be done. (2) Wastewater has high content of organic matter, good biodegradability, and high content of suspended solids. The sewage contains a lot of blood, oil, meat, visceral dirt and undigested food, etc., and has a disgusting blood red color. and the smell of blood. If this type of wastewater is directly discharged into the municipal pipe network without treatment, it will bring great trouble to the sewage treatment plant, so this type of wastewater must...
