[0002] Water resources are the most precious natural resources for human survival and development. With economic development and population growth, urban water consumption and domestic wastewater are increasing. Among various sewage treatment schemes, the use of sewage treatment equipment is an indispensable auxiliary measure.

[0003] To this end, the Chinese patent provides an industrial wastewater purification treatment device for reducing sewage discharge (publication number: CN208471825U), which uses a chain track combined with two arm guide wheels to rotate back and forth to enable the tugboat arm to pull the scraper, and follow the chain track to move left and right on the crawler frame to eliminate suspended impurities in the flotation tank sewage to prevent waste accumulation, ensuring that the equipment can achieve the purpose of complete sewage purification.

[0004] However, in the actual use of the above technical solution, the sewage is always in the same pool. Because the quality of the sewage may be too much, it affects the reaction between the sewage and the flocculant, resulting in a lack of timeliness in control, which in turn affects the sewage treatment effect, resulting in poor practicality.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 2 As shown, this embodiment is an industrial wastewater purification and discharge treatment device, including a fixed frame 1, in which cavity one 101, cavity two 102 and cavity three 103 are arranged, cavity one 101, cavity two 102 and cavity three 103 are connected by a water pump, and a treatment component 2 is movably installed in the fixed frame 1.

[0029] The processing component 2 includes a rotating rod 1 201, a rotating rod 202 and a rotating rod 3 203. The rotating rod 1 201 is located in the cavity 101, the rotating rod 202 is located in the cavity 2 102, and the rotating rod 3 203 is movably installed on one side of the cavity 3 103. The rotating rod 1 201 and the rotating rod 2 202 are both fixedly installed with stirring rods. The rotating rod 1 201 and the rotating rod 2 202 are connected by a belt transmission, and the rotating rod 2 202 and the rotating rod 3 203 are connected by a belt transmission. A motor is fixedly installed in the fixed frame 1, and the output end of the motor is fixedly connected to the rotating rod 1 201. The rotating rod 1 201 is driven to rotate by the motor, and then the rotating rod 2 202 and the rotating rod 3 203 are driven to rotate synchronously.

[0030] That is, cavity one 101 is used as a pre-flocculation tank, cavity two 102 is used as a main flocculation tank, and cavity three 103 is used as a post-flocculation tank. The pre-flocculation tank is mainly used to initially remove larger suspended matter and some soluble pollutants, and the main flocculation tank is used to further enhance the flocculation effect and remove fine suspended matter and soluble pollutants.

[0031] Specifically, the concentration of flocculant in the pre-flocculation tank is 0.5-2 mg / L. In the initial treatment stage, a lower concentration of flocculant or alum is used. The main purpose is to remove large suspended particles and some pollutants that are easy to settle in the water. Low concentration of flocculant can avoid excessive use and avoid unnecessary burden on water quality.

[0032] The sewage flow rate in cavity 101 is 0.1-0.5 m / s. The flow rate is relatively slow at this stage to ensure that the flocculant can fully contact and react with the particles in the sewage to avoid the flocculant from being unable to fully function due to excessive water flow. The reaction time is 5-15 minutes, which is relatively short because the main purpose is to remove larger particles. The flocculation reaction is faster and does not require too much time for deep reaction.

[0033] The flocculant concentration in the main flocculation tank is 5-10 mg / L. In the main flocculation tank, a higher concentration of flocculant or alum is used. At this time, the suspended particles remaining in the water are finer, and a higher flocculant concentration is required to ensure that more pollutants can be effectively aggregated. Properly increasing the flocculant concentration helps to further promote particle aggregation and improve the sedimentation of flocs.

[0034] The sewage flow rate in cavity 2 102 is 0.3-1m / s. At this stage, the flow rate is moderate to avoid excessive water flow affecting the flocculation reaction, while also ensuring sufficient contact between the sewage and the flocculant. The reaction time is 10-20 minutes. The reaction time of the main flocculation tank needs to be moderate to give enough time for the particles to aggregate and react. At this time, the flocculation and sedimentation of finer particles will be more dependent on time to ensure their complete flocculation.

[0035] The flocculant concentration in the post-flocculation tank is 0–5 mg / L. Since most of the suspended particles have been removed in the first two stages, the flocculant concentration in this stage can be reduced, or even no flocculant can be added at all. This stage is mainly to remove fine suspended matter and soluble pollutants.

[0036] And the sewage flow rate in cavity three 103 is 0.1-0.3 m / s, and slow flow is required at this time to promote the removal process. The reaction time is 15-30 minutes. The reaction time is relatively long because this period of time is mainly used to further remove trace pollutants in the water.

[0037] In the multi-stage design, the flocculant concentration can be adjusted according to the needs of each pool section. The first section uses low-concentration flocculant to avoid waste. The second section adds higher concentration flocculants as needed to effectively aggregate fine particles. The third section basically does not require additional flocculants, reducing the use of chemicals. Through segmented addition, more sophisticated chemical management can be achieved, avoiding situations where the concentration in a single pool section is too high or too low, thereby improving the efficiency of flocculant use.

[0038] Example 2: Please refer to Figure 3 - Figure 6 As shown, the present invention also includes an air outlet pipe 1 204 and an air outlet pipe 206. An air outlet pipe 1 204 is fixedly installed on one side of the cavity 101, a slag discharge pipe 205 is fixedly installed on the side of the cavity 101 away from the air outlet pipe 1 204, an air outlet pipe 206 is fixedly installed on the bottom of the cavity 3 103, a scraper 207 is movably installed on the top of the cavity 3 103, and a liquid discharge port 208 is opened on one side of the top of the cavity 3 103.

[0039] A rotating rod 209 is movably installed on one side of the fixed frame 1, and the rotating rod 209 is located on one side of the cavity 101. A turntable 210 is fixedly installed on the bottom of the rotating rod 209, and a connecting rod 211 is movably installed on the turntable 210. A fixed tube 212 is fixedly installed on the bottom of the fixed frame 1, and a moving rod 213 is movably installed in the fixed tube 212. One end of the moving rod 213 is movably connected to the connecting rod 211, and an air bag 214 is fixedly installed in the fixed tube 212. One side of the air bag 214 is fixedly connected to the moving rod 213. The air bag 214 is fixedly connected to the outlet pipe 204 through a pipeline. A plurality of nozzles are fixedly installed on the outlet pipe 204, and an intake pipe 215 is fixedly installed at the bottom of the air bag 214.

[0040] The rotating rod four 209 is connected to the rotating rod one 201 through a belt. When the rotating rod one 201 rotates, the rotating rod four 209 rotates synchronously, thereby driving the turntable one 210 to rotate, thereby driving the moving rod one 213 to move in the fixed tube one 212, and then periodically squeezing the air bag one 214, so that the gas in the air bag one 214 periodically enters the air outlet pipe one 204 and is sprayed out through the nozzle, thereby driving the sewage in the cavity one 101 to flow, and pushing the flocculated impurities to move to the slag discharge pipe 205, wherein the slag discharge pipe 205 is fixedly connected to a peristaltic pump through a pipeline, and the flocculated impurities are discharged through the peristaltic pump.

[0041] A turntable 216 is fixedly installed at the bottom of the rotating rod 3 203, a connecting rod 217 is movably installed on the turntable 216, a fixed tube 218 is fixedly installed at the bottom of the fixed frame 1, a moving rod 219 is movably installed in the fixed tube 218, one end of the moving rod 219 is movably connected to the connecting rod 217, an airbag 220 is fixedly installed in the fixed tube 218, one side of the airbag 220 is fixedly connected to the moving rod 219, the airbag 220 is fixedly connected to the outlet pipe 206 through a pipeline, a plurality of nozzles are fixedly installed on the outlet pipe 206, and an intake pipe 221 is fixedly installed at the bottom of the airbag 220.

[0042] When the rotating rod 202 rotates, the rotating rod 3 203 rotates synchronously therewith. At this time, the turntable 216 rotates, and then periodically squeezes the airbag 220, so that the gas in the airbag 220 enters the outlet pipe 206 and is sprayed out through the nozzle, thereby generating a large number of bubbles at the bottom of the cavity 3 103. During the floating process of the bubbles, the suspended impurities are moved to the top of the liquid surface and scraped off by the scraper 207.

[0043] The nozzle, the air intake pipe 1 215 and the air intake pipe 2 221 are all fixedly installed with a one-way valve for controlling the gas flow direction, so as to prevent the gas from flowing back into the air outlet pipe 1 204 and the air outlet pipe 2 206, and ensure that the air bag 1 214 and the air bag 2 220 always absorb gas from the environment.

[0044] A worm gear 222 is movably mounted on one side of the fixed frame 1, and the worm gear 222 is movably connected to the rotating rod three 203 through a thread. A screw rod 223 is fixedly mounted on one side of the worm gear 222, and the screw rod 223 is movably mounted inside the fixed frame 1. A moving block 224 is movably mounted on the screw rod 223 through a thread. The moving block 224 is fixedly connected to the scraper 207, and the bottom of the scraper 207 is flush with the drain port 208.

[0045] When the rotating rod 203 rotates, the worm wheel 222 is driven to rotate through the thread, thereby driving the screw 223 to rotate, wherein the screw 223 is provided with a reciprocating thread, which is not drawn in the figure. The screw 223 and the moving block 224 form a reciprocating screw 223 transmission structure through the thread. When the screw 223 rotates, the moving block 224 makes horizontal reciprocating motion on the screw 223, thereby driving the scraper 207 to reciprocate and scrape impurities on the liquid surface.

[0046] Specifically, when sewage enters the device, it drives the rotating rod 1 201 to rotate, and the rotating rod 202 and the rotating rod 3 203 are driven to rotate synchronously through the rotating rod 1 201. The sewage is stirred by the stirring rod to make it fully mixed with the reagent, and the gas is ejected from the gas outlet pipe 1 204 and the gas outlet pipe 2 206 through the linkage cooperation of various structures. On the one hand, the impurities flocculated in the cavity 101 flow to one side of the cavity 101 for subsequent discharge. On the other hand, a large number of bubbles are generated at the bottom of the cavity 3 103, which drives the suspended particles in the sewage to move to the top of the liquid surface and are scraped off by the scraper 207, thereby further improving the sewage treatment effect.

[0047] Combining Example 1 and Example 2, it can be seen that the multi-stage design allows the flocculant concentration to be regulated according to the needs of each pool section, achieving more refined drug management, avoiding the situation where the concentration of a single pool section is too high or too low, and improving the use efficiency of the flocculant. At the same time, through the linkage of multiple structures, on the one hand, the flow direction of impurities in cavity 101 is controlled to facilitate subsequent discharge. On the other hand, a large number of bubbles are generated at the bottom of cavity three 103, driving the suspended particles in the sewage to move to the top of the liquid surface, and scraping them off through the scraper 207, further improving the sewage treatment effect.
