Abstract

The invention provides an integrated electrochemical treatment device for deep treatment and a deep treatment method, relates to an electrochemical treatment device and a method for performing deep treatment through the device and aim to solve the problem that only a single pollutant is treated in the existing electrochemical treatment process. The device comprises a cylinder, a water inlet, a water outlet, a cathode, an anode, an iron net, a peristaltic pump, a direct-current stabilized power supply, an air blower, a first baffle, a second baffle, a third baffle, a fourth baffle, a fifth baffle, a sixth baffle, a microporous aeration pipe, an annular partition board, an outer cylinder sludge discharge port, an inner cylinder sludge discharge port and a water tank. The method comprises steps as follows: 1, the peristaltic pump is started, wastewater in the water tank enters a cathode reaction region from the water inlet through the peristaltic pump, and the air blower is started; 2, the air blower is shut off, the stabilized power supply is started, then water flows out naturally from the water outlet, after the reaction ends, a valve at the sludge discharge port is opened, and precipitated sludge is discharged out from the sludge discharge port. The integrated electrochemical treatment device for deep treatment and the deep treatment method are used for the field of sewage treatment.

Description

technical field [0001] The invention relates to an electrochemical treatment device and a method for advanced treatment using the device. Background technique [0002] In today's increasingly scarce water resources, water shortage is becoming an important factor restricting economic development, so the development of water reuse will be the only way for my country to achieve sustainable development. my country's "Twelfth Five-Year Plan" for environmental protection clearly requires the promotion of sewage recycling. In order to treat sewage into water that meets the water quality standards of reclaimed water, several steps of treatment are generally required: pretreatment, biochemical treatment and advanced treatment. Among them, the key to the reuse of reclaimed water that uses the secondary effluent of urban sewage plants and industrial wastewater as the water source lies in the advanced treatment stage. [0003] The advanced treatment methods are currently relatively ma...
