Abstract

The invention relates to a chemical wastewater biochemical treatment system, comprising a pretreatment unit, a filter biochemical unit, an oxidation unit, and a disinfection unit; the oxidation unit includes an oxidation chamber, a water inlet pipeline, a water outlet pipeline, a gas-liquid mixing channel, and a temperature detection unit device, constant temperature device, liquid level detection device, air pressure adjustment device, and central control device. The beneficial effect of the present invention is that the central control device can determine the opening of the first opening valve and the second opening valve according to the COD value in the waste water to be oxidized, and according to the liquid level height of the waste water to be oxidized Adjust the opening of the first opening valve; the central control device is set with an oxidation reaction time length, after the oxidation time reaches the standard, detect the residual COD value in the wastewater, and the central control device can determine the oxidation compensation time according to the residual COD value . Accelerate the oxidation reaction time and shorten the reaction time in the wastewater treatment process.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biochemical treatment system for chemical wastewater. Background technique [0002] O 3 / H 2 O 2 The system is a main advanced oxidation method used in water treatment. The synergistic effect of ozone and hydrogen peroxide can generate hydroxyl radicals with strong oxidation effect, which can effectively remove organic pollutants in water. Ozone is decomposed in water by the formation of hydroxyl radicals. From the point of view of the reaction mechanism, hydroxyl radicals have the role of initiating groups. [0003] current O 3 / H 2 O 2 In the combined wastewater treatment technology, due to the slow fusion rate of ozone in water, ozone is easily volatilized into the air, resulting in long wastewater treatment time. SUMMARY OF THE INVENTION [0004] To this end, the present invention provides a chemical wastewater biochemical treatment system to overcome the ...
