Abstract

The invention discloses a treatment method for papermaking waste water. Components comprise a buffer pool, an inclined filtering mesh, a grit chamber, a high-speed filter tank, a crushed ice condensate pool, a rotary adsorption pool, an aeration tank, a regulation pool, a biochemical reaction tank, a secondary settling tank, a staying pool, an artificial pond, a water storage tank, a sludge storage pond, a belt press filter machine and the like. The temperature inside the crushed ice condensate pool device is minus 5 DEG C to 15 DEG C. According to the waste water treated by the method disclosed by the invention, the removal rate of chemical oxygen demand reaches 97.9%. The removal rate of total nitrogen reaches 96.3%, the removal rate of five-day biochemical oxygen demand reaches 95.9%, the removal rate of suspended matters reaches 98.6%, the removal rate of chrominance reaches 98.1%, and the removal rate of turbidity reaches 99.8%.

Description

technical field [0001] The invention relates to a treatment method for papermaking wastewater, which belongs to the field of water treatment in environmental protection. Background technique [0002] At present, COD emissions in my country's paper industry wastewater discharge rank first among all types of industrial emissions, and the paper industry has the most serious pollution to the water environment. It is not only the primary issue of pollution prevention and control in my country's paper industry, but also the standard treatment of industrial wastewater in my country. primary issue. According to statistics, the discharge of industrial wastewater from papermaking and paper products at or above the county level in my country accounts for 18.6% of the total industrial discharge in the country, of which the amount of treatment discharges up to the standard accounts for 49.3% of the total discharge of wastewater from papermaking enterprises, and COD in the discharged waste...
