Abstract

The invention relates to a chemical wastewater biochemical treatment system which comprises a pretreatment unit, a filtration biochemical unit, an oxidation unit and a disinfection unit, the oxidation unit comprises an oxidation chamber, a water inlet pipeline, a water outlet pipeline, a gas-liquid mixing channel, a temperature detection device, a constant temperature device, a liquid level detection device, an air pressure adjusting device and a central control device. The device has the beneficial effects that the central control device can determine the opening degree of the first opening degree valve and the opening degree of the second opening degree valve according to the COD value in the to-be-oxidized wastewater, and the opening degree of the first opening degree valve is adjusted according to the liquid level height of the to-be-oxidized wastewater; the central control device is provided with an oxidation reaction time length, after the oxidation time length reaches the standard, the residual COD value in the wastewater is detected, and the central control device can determine the oxidation compensation time length according to the residual COD value. The oxidation reaction time in the wastewater treatment process is shortened, and the reaction duration is shortened.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a chemical wastewater biochemical treatment system. 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 produce hydroxyl radicals with strong oxidation effect, which can effectively remove organic pollutants in water. Ozone is decomposed in water through the formation of hydroxyl radicals. From the perspective of reaction mechanism, hydroxyl radicals have the role of initiators. [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 easy to volatilize into the air, resulting in long wastewater treatment time. Contents of the invention [0004] For this reason, the present invention provides a kind of chemical industry wastewater biochemical treatment system, in ord...
