Problems solved by technology

[0005] (1) The advantages of chemical treatment of COD are low equipment cost, good treatment effect, and simple operation; the disadvantage is that chemical agents need to be continuously injected into the wastewater, and its operating cost is high. It is often used to treat wastewater with complex components
[0006] (2) The advantages of biochemical treatment of COD are high efficiency in removing dissolved or colloidal organic matter, good effluent quality, and good sludge s

Abstract

The invention discloses a treatment system for removal of COD (chemical oxygen demand) in industrial waste water. The treatment system comprises a collecting well, a coarse screen, a primary sedimentation tank, a pH value adjusting tank, a nano micropore ultrasonic batch polymerization reactive tank, a secondary sedimentation tank, an aeration nitrifying tank, a biological denitrification tank, a water purifying tank and the like. The system creatively uses a synergistic chemical effect of specific-frequency ultrasonic waves (25100-27800 Hz), and organic substances in the waste water under this condition can generate C-H bond fracture and rapid recombination on the surface of a nano microporous membrane material, thus a polymerization reaction happens on the surface of a nano microporous surface polymer; and when an ultrasonic catalytic reaction and a mixing process occur intermittently and alternately, the molecular weight of an organic polymer can increase constantly, so that large-particle insoluble matters are gradually formed by converging, fall off from the surface of the nano microporous membrane material, are dispersed in the waste water in the form of suspended matters, and are finally removed through a precipitation process.

Description

technical field [0001] The invention relates to a treatment system for removing COD in industrial wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] COD (ChemicalOxygenDemand) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples. The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. Therefore, chemical oxygen demand is usually used as an index to measure the content of organic substances in water. The greater the chemical oxygen demand, the more serious the pollution of the water body by organic substances. In the study of river pollution and industrial wastewater properties and the operation and management of wastewater treatment plants, it is an important and quickly measured organic pollution parameter, and it is also one of the ...
