Abstract

A novel intelligent electric flocculation treatment apparatus of power plant coal-containing wastewater is characterized in that the apparatus comprises a coal water primary precipitation tank (1), a secondary precipitation tank (3), a high frequency pulse power supply (7), a vertical electric flocculation box (8), a micro-aeration blower (11), a clarifier (14), a middle water tank (17) and a clear water tank (24), the middle-upper portion of the vertical electric flocculation box (8) is provided with a pole plate (9), the lower portion of the vertical electric flocculation box (8) is provided with a mud hopper (10), coal water goes through an elevator pump (18), enters the vertical electric flocculation box (8) and is electrically flocculated, the electrically flocculated coal water automatically flows into the clarifier (14) and is clarified, the clarified coal water flows into the middle water tank (17), the coal water is conveyed to a valveless filter (19) through a middle water tank elevator pump (18) and is filtered for reuse, an inlet water online turbidity meter (6) is in current connection with the high frequency pulse power supply (7), and the electric flocculation current is automatically adjusted according to the turbidity change of the inlet water. The running of the apparatus can be fully automatically controlled. The apparatus has the characteristics of novel technology, automatic control, stable running, energy consumption and investment cost saving, and substantial environmental and economic benefits.

Description

technical field

[0001] The present invention and a new device for treating coal-containing wastewater in power plants, especially a treatment that has electro-flocculation reaction of coal-containing wastewater, clarification and separation of coal slime water, and filtration technology, and can operate intelligently and effectively remove suspended matter in wastewater The device is specifically a new type of device for intelligent electrocoagulation treatment of coal-containing wastewater. Background technique

[0002] At present, a certain amount of coal-containing wastewater will be produced in the coal transportation system of thermal power plants. The main pollution factor in the wastewater is as high as 15,000-20,000 mg / L of suspended solids, and the turbidity is greater than 10,000 NTU. Primary sedimentation tanks and secondary sedimentation tanks are usually set up for the treatment of coal-containing wastewater in power plants. Settling tank, primary settling tank ...
