Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device for landscaping. Background Art

[0002] Landscaping is the use of engineering and artistic means to create beautiful natural and recreational spaces, such as courtyards and parks, by transforming terrain and planting plants. In this process, sewage is generated due to various reasons, such as soil pollutants carried by irrigation surplus water, rainwater washing away ground pollutants, regular water changes in landscape water bodies, improper waste disposal in greening maintenance operations, and irrational use of chemicals. If discharged directly without treatment, these sewage will pollute the environment and damage the ecology. Therefore, the treatment of garden sewage is of great significance. It can not only recycle water resources to alleviate shortages, but also comply with environmental protection regulations. For example, a sewage treatment device for landscape gardening disclosed in application number 202111304215.9 is a device for treating garden sewage.

[0003] Existing landscaping sewage treatment devices usually perform multi-stage treatment on sewage, and usually filter out larger impurities through a filter screen first. However, the existing sewage treatment devices can only filter out impurities, but cannot clean them out. Therefore, in the subsequent sewage treatment process, the sewage treatment and filtration efficiency will be reduced, and the filter screen may be blocked by impurities, causing poor water flow and even equipment failure. After the sewage is filtered, flocculants are needed to condense suspended particles, remove organic matter, and remove phosphorus and nitrogen. However, the existing landscaping sewage treatment devices usually use the rated flocculant dosage to treat sewage each time, and cannot adaptively adjust the amount of flocculant added according to the actual pollution situation of the sewage. When treating sewage with a light pollution degree, if the flocculant is still added according to the rated dosage, the excess agent cannot play a role, resulting in unnecessary waste. When encountering seriously polluted sewage, the rated amount of flocculant added may not be enough to fully condense the pollutants in the sewage. After the flocculant treatment is completed, the sewage is usually disinfected, for example, using ultraviolet disinfection. However, the existing ultraviolet disinfection cannot adaptively adjust the ultraviolet disinfection power according to the flocculation situation. When the flocculation effect is better and there are fewer impurities in the water, if the ultraviolet disinfection power remains at a high level, it will cause energy waste, because at this time a lower power may be enough to achieve a good disinfection effect, but the equipment is still running at high power, increasing unnecessary energy consumption costs.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The first motor in the impurity discharge mechanism drives the rotating rod to rotate, and the attraction of the electromagnet and the permanent magnet block drives the connecting rod and the collection frame to rotate to clean the impurities on the filter plate. When the impurities block the filter hole and increase the resistance of the collection frame, a speed difference occurs between the rotating rod and the collection frame, and the paddle plate contacts the baffle plate, causing the baffle plate to flip and block the entrance of the collection frame. After the collection frame rotates and hits the blocking block, the hydraulic jet pump starts and uses the reaction force to push itself forward to clean the impurities and push them out. Therefore, this device can not only filter impurities, but also automatically clean impurities to prevent impurity accumulation from affecting processing efficiency and causing equipment failure.

[0014] 2. The squeezing plate in the first liquid storage tank in the agent delivery mechanism is squeezed by the gravity of impurities. The more impurities there are, the greater the distance the squeezing plate moves, and the more flocculants enter the temporary storage shell. Therefore, the flocculants discharged into the flocculation space are proportional to the impurities cleared out. The impurities in the sewage are flocculated by the flocculants, and after flocculation, the amount of foaming agent delivered is controlled according to the amount of flocculants delivered. The amount of flocculants added can be adaptively adjusted according to the actual pollution situation of the sewage to avoid waste or insufficient agents.

[0015] 3. After flocculation and foaming are completed, the fourth electric telescopic rod is extended through the PLC controller to drive the infrared transmitter to rise. At the same time, the conductive sheet moves on the resistor plate to change the current of the sliding rheostat. The infrared light passes through the sewage and shoots towards the infrared receiver. When the infrared intensity changes significantly, it indicates that the infrared light enters the foam part. At this time, the PLC controller records the current. When the infrared transmitter moves to the top of the foam, the infrared receiver clearly receives the infrared light. The PLC controller records the current again. The bubble thickness can be calculated through the two current differences. The more impurities in the sewage, the thicker the bubbles produced, and the greater the required ultraviolet disinfection intensity. Therefore, when the sewage enters the disinfection space, the PLC controller will adjust the power of the ultraviolet lamp ring according to the calculated bubble thickness, so as to adjust the disinfection intensity adaptively according to the flocculation and foaming conditions.

[0026] A disinfection groove 98 is provided on the inner wall of the processing box 1, and the disinfection groove 98 is located in the horizontal space of the disinfection space 6.

When the conductive sheet 96 slides upward on the resistor plate 97, the resistance of the sliding rheostat in the detection circuit gradually decreases.

[0027] A first water outlet 12 and a second water outlet 13 are provided at the eccentric parts of the first partition plate 10 and the second partition plate 11, and a first solenoid valve and a second solenoid valve are respectively provided in the first water outlet 12 and the second water outlet 13. A water pump 14 is fixedly connected to the bottom end of the treatment box 1, and the water pumping end of the water pump 14 is fixedly connected to the inside of the treatment box 1, and the water outlet end of the water pump 14 is fixedly connected to a water outlet pipe 15. The PLC controller is electrically connected to the first solenoid valve, the second solenoid valve and the water pump 14 to form a circulation loop, and a water inlet pipe is fixedly connected to the top end of the treatment box 1, wherein the water inlet pipe can be connected to an external container for storing sewage, and impurities that are too large need to be filtered out in the water storage container to prevent damage to the inside of the treatment box 1.

[0028] The working principle of the present invention is as follows: First, the sewage is discharged into the filter space 3 in the treatment box 1 through the water inlet pipe, and the first motor 73 and the electromagnet 75 are started at the same time. Through the strong attraction between the electromagnet 75 and the permanent magnet, the permanent magnet and the protective shell 76 can be driven to rotate synchronously in the process of the first motor 73 driving the rotating rod 74 to rotate, and the connecting rod 77 can be driven to rotate synchronously. The collecting frame 71 is driven to rotate through the connecting rod 77, and the impurities on the filter plate 2 are cleaned through the collecting frame 71, and the impurities are made to enter the collecting frame 71. Since the collecting frame 71 rotates continuously, the impurities will not float out of the collecting frame 71 due to the reaction force of the sewage. As the impurities are collected, the impurities therein will clog the filter holes 79, thereby increasing the resistance of the collection frame 71. As a result, the rotation speed of the rotating rod 74 will be faster than that of the collection frame 71. Due to the speed difference between the rotating rod 74 and the collection frame 71, the rotating rod 74 will drive the protective shell 76 and the dial plate 711 to slowly rotate to the rear side of the collection frame 71 (rearward of the rotation direction), thereby making the dial plate 711 contact with the baffle plate 725, so that the baffle plate 725 is turned toward the opening of the collection frame 71. Since the baffle plate 725 has a pressure sensor, after the baffle plate 725 contacts the collection frame 71, the pressure sensor will transmit an electrical signal to the PLC controller, and then the PLC controller will control the electromagnetic sheet to be energized and the control unit 71 to be turned over. An electric telescopic rod 723 pushes the blocking block 724 outward, and adsorbs the baffle 725 through the electromagnetic sheet, so that the baffle 725 blocks the entrance of the collection frame 71. When the collection frame 71 rotates and contacts the blocking block 724, the pressure sensor in the blocking block 724 will send an electrical signal to the PLC controller, and then the hydraulic jet pump 721 is controlled by the PLC controller to start, and the external sewage is pumped out through the hydraulic jet pump, and then discharged from the rear side. According to Newton's third law, the action of force is mutual. When the hydraulic jet pump discharges sewage from the rear side, a forward reaction force is generated, which pushes the hydraulic jet pump 721 to move forward, and the impurities are cleaned and pushed out through the front of the hydraulic jet pump 721; After the hydraulic jet pump 721 is started for a period of time (the period of time is the time when the hydraulic jet pump 721 is about to push out the impurities after being tested in advance, and the purpose is to prevent the sewage from being discharged from the discharge port 726 in advance. Although a little sewage will be discharged with the above method, the sewage is very small and can be ignored), the second electric telescopic rod 728 is started to drive the blocking block 729 to move upward through the second electric telescopic rod 728, so that the discharge port 726 leaks out, and the impurities are discharged through the discharge port 726 to the squeezing plate 83 in the first liquid storage tank 81. The squeezing plate 83 is squeezed downward by the gravity of the impurities, and the flocculant is squeezed into the temporary storage shell 85 for subsequent use; Since the opening and closing times of the first solenoid valve and the second solenoid valve are pre-tested, the sewage in the flocculation space 5 and the disinfection space 6 can be treated, and the opening time of the first solenoid valve is always later than that of the second solenoid valve. The reason is that the treated sewage in the disinfection space 6 needs to be discharged through the water pump 14 first, and then the sewage in the flocculation space 5 can be allowed to enter the disinfection space 6 for treatment, and then the sewage in the pre-storage space 4 can be discharged into the flocculation space 5, so that the sewage cannot enter the filtration space 3. When the sewage in the pre-storage space 4 is discharged into the flocculation space 5, it can continue to be discharged. The above-mentioned time intervals and time durations are pre-tested, and the duration and interval are the upper limits of the sewage that can be treated, and are all controlled by the PLC controller, wherein the water inlet pipe is closed after being opened for a certain period of time, and the opening time is consistent each time, so the amount of sewage treated each time can be guaranteed to be consistent.

[0029] Since the sewage filtered by the filter space 3 is stored in the pre-storage space 4, all the sewage in the pre-storage space 4 will enter the flocculation space 5, and the more impurities generated by the filtration, the more finer impurities will remain in the sewage. The reason is that when there are a large number of impurities in the sewage, it means that the content of impurities of various sizes in the sewage is relatively high. Large impurities are retained by the filter plate 2, but for smaller impurities, a larger part may still be able to pass through the pores of the filter plate 2 into the pre-storage space 4. Therefore, the more impurities generated by the filtration, the greater the moving distance of the squeezing plate 83, and thus the more flocculants enter the temporary storage shell 85.

[0030] The PLC controller controls the first solenoid valve to be opened, so that the sewage in the pre-storage space 4 enters the flocculation space 5, and at the same time, the metering solenoid valve is opened to allow the flocculant to enter the flocculation space 5. At the same time, the second motor 89 is controlled by the PLC controller to start, and the stirring rod 810 and the stirring plate 811 are driven to rotate by the second motor 89, so that the sewage and the flocculant are fully contacted, so that the effective ingredients in the flocculant can be quickly and evenly dispersed into the sewage, fully contact and react with the impurities in the sewage, and the time required for the flocculation reaction is greatly shortened, so that the impurity particles gather together to form a larger floc (existing technology); The PLC controller calculates the amount of flocculants entering the flocculant space 5, and the amount of foaming agents that need to be discharged into the flocculant space 5 is calculated based on the calculated flocculant amount. The reason is that the more impurities generated by filtration, the higher the content of impurities of various sizes in the sewage. After preliminary filtration, more fine impurities enter the pre-storage space 4, which means that the sewage is highly polluted and the water quality is poor. More flocculants are needed for treatment to achieve a better flocculation effect and condense the impurities into larger flocs. Since there is a positive correlation between the impurity content and the amount of flocculants used, and the flocculation process is the subsequent The basis of the foaming process (the flocculation process is the basis of the subsequent foaming process, mainly because in terms of physics, the flocculant can make the fine impurity particles in the sewage aggregate to form larger flocs, increase the particle size, and change the surface properties of the impurity particles, making it easier to combine with bubbles). The state and quantity of flocs after flocculation will affect the foaming effect. Therefore, based on the demand for the amount of flocculant due to the impurity content, the demand for the amount of foaming agent can be further inferred. After the flocculation is completed (the flocculation time is pre-tested), the water pump in the infusion structure is controlled by the PLC controller to transport the foaming agent to the flocculation space 5.

[0031] The foaming agent is mixed with the flocculated sewage by the stirring rod 810 and the stirring plate 811. The stirring can make the foaming agent contact with the water more fully and disperse in the water, reduce the surface tension of the water, and make it easier for air to form bubbles in the water. After the bubbles are generated, the bubbles will interact with the flocculent impurities in the flocculated sewage. Due to factors such as surface tension, the flocculent impurities will adhere to the surface of the bubbles or be wrapped by the bubbles to form a gas-solid combination. The density of the bubbles is less than that of water, and the bubbles will float to the surface of the sewage with the attached flocculent impurities. Then, the fourth electric telescopic rod 94 is controlled by the PLC controller to extend upward, thereby driving the infrared transmitter 95 to move upward in the process of emitting infrared rays, and driving the conductive sheet 96 to move on the resistor plate 97. , thereby changing the current passing through the sliding rheostat. The infrared ray passes through the sewage and irradiates the infrared receiver 93. When the intensity of the infrared ray received by the infrared receiver 93 changes, it enters the foam part. Therefore, the foam will reflect and diffuse the infrared ray. Therefore, the infrared ray received by the infrared receiver 93 changes greatly. At this time, the current size at this time is recorded by the current detection module in the PLC controller. As the infrared transmitter 95 continues to move, the infrared transmitter 95 will slowly move to the top of the bubble. After moving to the top, the infrared receiver 93 will clearly receive the infrared ray. At this time, the current size at this time is recorded by the current detection module in the PLC controller, and the thickness of the bubble is calculated based on the current difference between the two times.

[0032] After the recording is completed, the gas-liquid mixed pump 815 and the third electric telescopic rod 816 are started by the PLC controller. The rotation of the stirring rod 810 drives the bubble extraction plate 814 to rotate, and the air in the bubble extraction plate 814 is extracted by the gas-liquid mixed pump 815, and then the bubbles are rotated out. At the same time, the third electric telescopic rod 816 pushes the bubble extraction plate 814 downward to move slowly downward. The downward movement distance of the bubble extraction plate 814 is calculated based on the current at the liquid level detected above. After reaching the liquid level, the gas-liquid mixed pump 815 is turned off and the third electric telescopic rod 816 is reset.

[0033] Sewage usually contains a large amount of organic pollutants, microbial metabolites and residual surfactants. Many of these substances are surface active and can reduce the surface tension of water, making it easy for air to disperse in water to form bubbles, thereby producing more foam. Therefore, the more impurities there are in the sewage, the more bubbles there are, so stronger infrared rays are needed for disinfection. Therefore, the bubble thickness of the sewage treated this time is recorded. When the sewage treated this time enters the disinfection space 6, the power of the ultraviolet lamp ring 910 is controlled by the PLC controller. The thicker the bubbles, the more impurities there are, so a greater intensity of ultraviolet radiation is required.

[0034] The above sewage treatment process can be roughly summarized into three levels of treatment: Primary treatment: The sewage is discharged into the filter space 3 in the treatment box 1 through the water inlet pipe, and the first motor 73 and the electromagnet 75 are started to drive the collection frame 71 to rotate, clean and collect the impurities on the filter plate 2. When the impurities block the filter holes and increase the resistance of the collection frame 71, the speed difference triggers a series of actions, and the hydraulic jet pump 721 pushes the impurities out and discharges them into the first liquid storage tank 81 through the discharge port 726, squeezing the flocculant into the temporary storage shell 85.

[0035] Secondary treatment: The filtered sewage is stored in the pre-storage space 4 and discharged into the flocculation space 5 in sequence. The PLC controller controls the opening of the first solenoid valve and the metering solenoid valve to mix the sewage with the flocculant. The second motor 89 drives the stirring to accelerate the flocculation reaction. Then, the amount of the foaming agent is calculated according to the amount of the flocculant. The infusion structure delivers the foaming agent. After stirring and mixing, the bubble thickness is detected by infrared rays.

[0036] Level 3 treatment: According to the bubble thickness, the PLC controller controls the power of the ultraviolet lamp ring 910. The gas-liquid mixed pump 815 and the third electric telescopic rod 816 cooperate to rotate and extract the bubbles, and perform ultraviolet disinfection on the sewage entering the disinfection space 6 to complete the treatment.
