Description

Technical Field

[0001] This utility model relates to the field of continuous treatment technology for chemical wastewater, specifically to a stepped continuous treatment device for chemical wastewater with adjustable flow rate. Background Technology

[0002] Pure water undergoes changes in its original physical or chemical properties after use, becoming wastewater containing various impurities. Chemical wastewater includes process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site washing water discharged during chemical production. If this wastewater is discharged without treatment, it will cause varying degrees of pollution to water bodies, thereby endangering human health and affecting industrial and agricultural production. Therefore, wastewater treatment equipment is generally required before its use.

[0003] A current continuous chemical wastewater treatment device (CN202021252242.7) can conveniently filter chemical wastewater. It is also easy to clean and maintain after disassembly. Wastewater enters through the feed pipe at one end of the machine body, flows into the cylinder inlet, passes through the filter cartridge, and then enters the filter element through the connecting port at the end of the cylinder inlet for further filtration. Afterward, it flows back into the cylinder inlet through the connecting port. This process is repeated for multiple continuous filtrations, ensuring thorough filtration of the chemical wastewater. However, this device has shortcomings: the treatment effect is poor, the flow rate cannot be adjusted, the protection effect is inadequate, and it is inconvenient to use. Therefore, a stepped continuous chemical wastewater treatment device with adjustable flow rate is needed to solve these problems. Utility Model Content
