Embodiment 1

[0030] 1) The dilute sulfuric acid storage tank is connected to the adjustment tank through the dilute sulfuric acid metering pump, and the online pH detection is interlocked with the dilute sulfuric acid metering pump.

[0031] Control the pH in the adjustment tank to be 3~6. When the pH in the adjustment tank is less than 3, the online pH detection will issue instructions to the dilute sulfuric acid metering pump to reduce the operating frequency of the dilute sulfuric acid metering pump and reduce the dosage of dilute sulfuric acid in the control and adjustment tank.

[0032] Control the pH in the adjustment pool to be 3~6. When the pH in the adjustment pool is less than or greater than 6, the online pH detection will issue instructions to the dilute sulfuric acid metering pump, increase the operating frequency of the dilute sulfuric acid metering pump, and increase the dosage of dilute sulfuric acid in the control adjustment pool.

Embodiment 2

[0045] 1) The dilute sulfuric acid storage tank is connected to the adjustment tank through the dilute sulfuric acid metering pump, and the online pH detection is interlocked with the dilute sulfuric acid metering pump.

[0046] Control the pH in the adjustment tank to be 4~5. When the pH in the adjustment tank is less than 4, the online pH detection will issue instructions to the dilute sulfuric acid metering pump to reduce the operating frequency of the dilute sulfuric acid metering pump and reduce the dosage of dilute sulfuric acid in the control and adjustment tank.

[0047] Control the pH in the adjustment tank to be 4~5. When the pH in the adjustment tank is greater than 5, the online pH detection will issue instructions to the dilute sulfuric acid metering pump, increase the operating frequency of the dilute sulfuric acid metering pump, and increase the dosage of dilute sulfuric acid in the control and adjustment tank.

Abstract

The invention provides a high-concentration organic wastewater catalytic oxidation process control system, comprising a regulating tank, a sewage lifting pump, a pneumatic regulating valve I, a fan, a catalytic oxidation tower, an emptying valve, a return valve, a flushing pump, an intermediate pool, a drain valve, Online COD monitor, central control system, dilute sulfuric acid storage tank, dilute sulfuric acid metering pump, mixing valve, multifunctional online monitor I, pneumatic control valve II, multifunctional online monitor II, pneumatic control valve III, oxidant storage tank, Oxidant metering pump, online pH detector. It is a new type of catalytic oxidation process and method with high degree of automatic control, high utilization rate of oxidant and dilute sulfuric acid, less dosage of chemicals, low operating cost and less difficult operation. It can be widely used in low biodegradability, high concentration, Pretreatment of toxic and harmful organic wastewater.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-concentration organic wastewater catalytic oxidation process control system. Background technique [0002] my country's industrial wastewater discharge in 2017 was about 19.55 billion tons, of which the chemical industry wastewater discharge was about 3.92 billion tons, involving petrochemical, synthetic chemical, pharmaceutical chemical, coal chemical, textile printing and dyeing industries. Industrial wastewater has serious environmental hazards, complex components, high concentration of organic pollution, high toxicity, poor biochemical properties, and difficult disposal. It is the top priority of sewage treatment. [0003] At present, the treatment technologies for high-concentration organic wastewater at home and abroad include: incineration, Fenton oxidation, wet catalytic oxidation, supercritical oxidation, catalytic oxidation and other advanced ...
