[0015] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] A harmless treatment device for chemical production wastewater, comprising a mixing tank 1, a filter tank 2, a feed tank 4, a filter plate 5 and a pump assembly, wherein the filter tank 2 is arranged beside the mixing tank 1, and the pump assembly is set between the mixing tank 1 and the filter tank 2, and the pump assembly pumps the fully mixed mixed liquid in the mixing tank 1 into the filter tank 2 for filtration, and a premixing chamber 11, a feed chamber 13 and a complete mixing chamber 12 are sequentially arranged in the mixing tank 1 along the flow order of the wastewater, and both ends of the feed chamber 13 are divided from the premixing chamber 11 and the complete mixing chamber 12 by a partition mesh plate 14, the upper end of the feed chamber 13 is open, and the feed tank 4 is set on the top of the feed chamber 13, and a feed pipe is set at the lower end of the feed tank 4 for feeding the feed chamber 13. A liquid inlet pipe 15 is provided on the side wall, and the untreated wastewater enters the mixing tank 1 from the liquid inlet pipe 15 and flows through the premixing chamber 11, the feeding chamber 13 and the complete mixing chamber 12 in sequence to complete sufficient mixing with the added material. A plurality of filter plates 5 are arranged at intervals in the filter tank 2, and the plurality of filter plates 5 isolate and divide the filter tank 2 into a plurality of filter chambers. The inlet side of the mixed liquid to be filtered is the primary filter chamber 25, and the discharge side of the mixed liquid after filtration is the ultimate filter chamber 26. There are any number of intermediate filter chambers between the primary filter chamber 25 and the ultimate filter chamber 26. The filtering capacity of the plurality of filter plates 5 between the primary filter chamber 25 and the ultimate filter chamber 26 is gradually improved. A drain pipe 22 is provided on the side wall of the ultimate filter chamber 26, and the mixed liquid after filtration is discharged from the filter tank 2 from the drain pipe 22.

[0017] The harmless treatment device for chemical production wastewater also includes an agitator 3 and a motor 6. An agitator 3 is rotatably arranged in each of the premixing chamber 11 and the complete mixing chamber 12. The tops of the two agitators 3 are respectively connected to the driving ends of the two motors 6. The two motors 6 independently drive the two agitators 3 to rotate. The agitator 3 in the premixing chamber 11 continuously rotates to stir the mixed liquid to keep it homogeneous. When the mixed liquid flows through the feeding chamber 13, it is mixed with the added material and then flows into the complete mixing chamber 12. At the same time, the added material put into the feeding chamber 13 flows to the premixing chamber 11 and the complete mixing chamber 12 respectively based on osmosis.

[0018] When the liquid inlet pipe 15 continues to inject the mixed liquid into the mixing tank 1, the pumping component does not work. At the same time, the mixed liquid is intercepted by the partition mesh plate 14 and is decelerated to seep into the feeding chamber 13. When the mixed liquid flows through the feeding chamber 13, it is mixed with the added material and seeps into the mixing chamber 12. The injection of the mixed liquid is stopped after the shaft of the mixing tank 1 is injected to a certain water level. At this time, the two agitators 3 continue to rotate, and the mixed liquids with different concentrations of added materials respectively located in the mixing chamber 12, the feeding chamber 13 and the premixing chamber 11 penetrate each other and are homogenized. After the mixed liquid is fully homogenized, the pumping component can be activated to pump the mixed liquid into the filter tank 2 for the filtration process.

[0019] The separation mesh plate 14 can be selected with different apertures according to specific usage requirements. While intercepting and buffering the water flow, the separation mesh plate 14 can intercept impurities mixed in the wastewater and concentrate the impurities in the premixing chamber 11, making it easier for staff to carry out centralized processing.

[0020] The water pumping assembly includes a water pump 8 and a bracket 9. The bracket 9 is installed between the mixing tank 1 and the filter tank 2. The water pump 8 is fixedly installed on the bracket 9. Pumping pipes 81 are provided on the water inlet and outlet ends of the water pump 8. The port of the pumping pipe 81 located in the mixing tank 1 is immersed below the liquid surface, and the port of the pumping pipe 81 located in the filter tank 2 is located in the primary filter chamber 25.

[0021] The chemical production wastewater harmless treatment device also includes multiple isolation plates 7, and multiple insertion seats 21 are fixedly provided on the pool wall of the filter pool 2, each of the insertion seats 21 is U-shaped and fits on the two opposite pool walls and the pool bottom of the filter pool 2, and each of the insertion seats 21 is set in an inclined posture with the upper end facing the discharge end and the lower end facing the liquid inlet end. A slot one 23 and a slot two 24 are provided on each of the insertion seats 21, and the slot one 23 is set close to the backwater side of the insertion seat 21, and the slot two 24 is set close to the frontwater side of the insertion seat 21. Multiple filter plates 5 are correspondingly inserted in multiple slots one 23, and multiple isolation plates 7 are intermittently inserted in multiple slots two 24. When the filter plate 5 needs to be replaced, the isolation plate 7 is activated. At this time, the isolation plate 7 is accurately inserted into the slot two 24 of the insertion seat 21 where the filter plate 5 to be replaced is located, and then the filter plate 5 is pulled out for replacement. After the filter plate 5 is completely replaced, the isolation plate 7 can be pulled out.

[0022] Water valves are provided in the liquid inlet pipe 15 and the liquid discharge pipe 22 , and a valve is provided in the feeding pipe of the added material tank 4 .

[0023] Working Principle: Chemical production wastewater that needs to be harmlessly treated is injected into the premixing chamber 11 through the liquid inlet pipe 15. At the same time, the additive tank 4 is used to add additives to the feeding chamber 13, and the two motors 6 are started to rotate the two agitators 3. The injected wastewater flows through the feeding chamber 13, where it mixes with the additives and then flows into the mixing chamber 12. When the wastewater reaches a certain level, the injection is stopped. After the injection is stopped, the two agitators 3 continue to operate. After the mixed liquid in the mixing tank 1 is stirred and homogeneous, the water pump 8 is started to pump the mixed liquid in the mixing tank 1 into the filter tank 2 and inject it into the primary filter chamber 25.

[0024] The mixed liquid injected into the filter tank 2 flows through the multiple filter plates 5 in sequence to complete the filtration process, and finally flows into the final filter chamber 26 and is discharged from the filter tank 2 through the drain pipe 22. The multiple filter plates 5 are selected according to the specific filtration requirements. Different filtration levels are selected. The number of multiple filter plates 5 arranged in the filter tank 2 can also be set according to the filtration requirements. When the filtration accuracy requirement is high, the number of filter plates 5 can be increased. By increasing the number of filtration levels, the filtration pressure required by a single filter plate 5 is reduced, ensuring water flow efficiency while improving filtration accuracy.

[0025] When the filter plate 5 needs to be replaced due to the increase of attachments after long-term operation, the isolation plate 7 is inserted into the second slot 24 to block the water-facing surface of the corresponding filter plate 5, and then the corresponding filter plate 5 is replaced. After the replacement is completed, the isolation plate 7 can be removed.

[0026] The overall wastewater treatment process within this device is based on basic chemical principles, including but not limited to acid-base neutralization, salting-out, and organic solvent precipitation. Appropriate additives are selected based on the physical and chemical properties of the wastewater to be treated to achieve harmless treatment. The multiple filter plates 5 can be made of different materials based on specific treatment needs. Adsorbent materials can be applied in addition to filtration to remove harmful substances from the mixed liquid through adsorption.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
