[0002] An enhanced pre-treatment wastewater treatment pond for ecological wetlands is a wastewater treatment facility designed to improve the quality of water entering the wetland system, bringing it within the wetland's tolerance range. It is a wastewater treatment device designed to prevent harmful substances in wastewater from polluting and damaging ecological wetlands. The treatment pond is suitable for ecological wetland systems of various sizes, including urban wetlands and rural wetlands, and has broad application prospects. However, current treatment ponds have limitations in use, such as limited functionality, difficulty in adjusting for different types of wastewater, and difficulty in cleaning the settled sludge. Utility Model Content

[0003] The purpose of this invention is to provide a pre-treatment enhanced sewage treatment tank for ecological wetlands to solve the above problems. It can easily adjust the sewage treatment mode according to different needs, has strong applicability, and facilitates the extraction of settled sludge, making it convenient to use.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: a pre-treatment enhanced wastewater treatment tank for ecological wetlands, comprising a tank assembly, the tank assembly including a treatment tank, and an inlet pipe and an outlet pipe with valves respectively installed at both ends of the treatment tank. A filter screen is threadedly connected to one end of the inlet pipe inside the treatment tank. A cover assembly is installed above the treatment tank, the cover assembly including a cover body that seals the upper end of the treatment tank. A baffle plate is fixedly installed in a horizontal array at the lower end of the cover body, and a wastewater treatment plate is installed on the baffle plate. The wastewater treatment plate can be a filter plate or a biological packing plate. When using a biological packing plate, anaerobic or aerobic microbial packing plates are selected according to the type of wastewater, facilitating microbial purification of wastewater and allowing for selection of different wastewater treatment plates based on different wastewater conditions, thus exhibiting strong applicability.

[0005] Preferably, the treatment tank is constructed of concrete, and the interior of the treatment tank is lined with a waterproof membrane. The interior of the treatment tank has slots, and the baffle plate is engaged with the slots. Through the slots, the interior of the treatment tank can be divided into individual chambers by the baffle plate for gradual treatment of sewage.

[0006] Preferably, a threaded pipe is fixedly installed inside the treatment tank on one side of the inlet pipe, and one end of the filter bag is threaded to the threaded pipe, which facilitates the installation of the filter bag and the collection of larger debris in the sewage through the filter bag.

[0007] Preferably, a funnel-shaped sludge collection hopper is fixedly installed at the lower end of the treatment tank, and a sludge suction pipe is fixedly installed at the lower end of the sludge collection hopper. The upper end of the sludge suction pipe extends to the upper end of one side of the treatment tank, and the upper end of the sludge suction pipe is sealed with a sealing cap, so that the sludge deposited inside the sludge collection hopper can be easily extracted after long-term use.

[0008] Preferably, a through hole is provided near the lower end of the baffle plate, and pin plates are rotatably installed on both sides of the baffle plate. The pin plates are located on both sides of the through hole and are arranged in a vertical array. The sewage treatment plate is located inside the through hole. The through hole facilitates the installation and replacement of the sewage treatment plate.

[0009] Preferably, a first air inlet pipe and a second air inlet pipe are fixedly installed on both sides of the upper end of the cover. A shut-off valve is fixedly installed on one side of both the first and second air inlet pipes. By opening the shut-off valves at the corresponding positions, it is convenient to ventilate the front or rear end of the treatment tank, and to introduce different gases according to different sewage treatment plates, which is conducive to the reproduction of microorganisms. The position of the ventilation can be adjusted according to the position of the first and second air inlet pipes. Furthermore, the sewage treatment plate is located below the baffle plate, so after the gas is introduced, the air pressure balance at both ends of the treatment tank is broken, which facilitates the flow of sewage.

[0010] Preferably, the lower end of the first air inlet pipe is close to the water inlet pipe, and the lower end of the second air inlet pipe is close to the water outlet pipe. The first air inlet pipe and the second air inlet pipe are connected. When the first air inlet pipe introduces gas into the treatment tank, it causes the sewage to flow faster toward the water outlet pipe. When the second air inlet pipe is ventilated, it causes the sewage to flow back and flush the impurities attached to the sewage treatment plate, thus preventing blockage.

[0011] Preferably, an air pump is fixedly installed on one side of the upper end of the cover. The air outlet of the air pump is connected to the first air inlet pipe and the second air inlet pipe, and the air outlet of the air pump is located in the middle of the two shut-off valves. The air pump facilitates the supply of air to the inside of the first air inlet pipe and the second air inlet pipe.

[0012] The beneficial effects of this utility model are: by using a cover plate assembly to seal the inside of the treatment tank, and by installing a sewage treatment plate, the sewage treatment plate can be replaced to facilitate switching treatment methods according to different sewage, and the air pump can be used to accelerate the water flow or perform backwashing treatment, and the sludge suction pipe can be used to easily remove the deposited sludge, making it convenient to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5As shown, a pre-treatment enhanced wastewater treatment tank for ecological wetlands includes a tank assembly 1, which includes a treatment tank 101. An inlet pipe 102 with valves and an outlet pipe 103 are respectively installed at both ends of the treatment tank 101. A filter screen 104 is threadedly connected to one end of the inlet pipe 102 inside the treatment tank 101. A cover assembly 2 is installed above the treatment tank 101, including a cover body 201 that seals the upper end of the treatment tank 101. Water baffles 202 are fixedly installed in a horizontal array at the lower end of the cover body 201. Wastewater treatment plates 203 are installed on the water baffles 202. The wastewater treatment plates 203 can be filter plates or biological packing plates. When using biological packing plates, anaerobic or aerobic microbial packing plates are selected according to the type of wastewater to facilitate biological purification of the wastewater and to allow for selection based on different wastewater conditions. Different wastewater treatment plates 203 can be selected, making them highly adaptable. When using filter plates, the mesh size of the filter plates increases sequentially from the inlet pipe 102 to the outlet pipe 103, improving the step-by-step filtration effect. When treating wastewater, external wastewater enters the treatment tank 101 through the inlet pipe 102. Upon entering the treatment tank 101, larger foreign objects in the wastewater are collected by the filter screen 104, achieving the effect of primary filtration. After primary filtration, the wastewater passes through the wastewater treatment plates 203 for further treatment. The treated wastewater is discharged through the outlet pipe 103. When cleaning or further treatment of wastewater is required, valves on the inlet pipe 102 and outlet pipe 103 create a sealed space inside the treatment tank 101 for further treatment. When no further treatment is required, the valves are opened, allowing the wastewater to flow.

[0021] The treatment tank 101 is constructed of concrete, with an impermeable membrane lining its interior. A slot 105 is provided inside the treatment tank 101, into which a baffle plate 202 is secured. The slot 105 allows the interior of the treatment tank 101 to be divided into individual chambers by the baffle plate 202 for gradual wastewater treatment. A threaded pipe 106 is fixedly installed on one side of the inlet pipe 102 inside the treatment tank 101. One end of a filter bag 104 is threadedly connected to the threaded pipe 106, and a threaded ring is fixedly installed on one end of the filter bag 104. The filter bag 104 is installed on the threaded pipe 106 by driving the threaded ring, facilitating the installation of the filter bag 104. Larger impurities in the wastewater are collected through the filter screen 104, facilitating wastewater pretreatment. A funnel-shaped sludge collection hopper 107 is fixedly installed at the lower end of the treatment tank 101, and a sludge suction pipe 108 is fixedly installed at the lower end of the sludge collection hopper 107. The upper end of the sludge suction pipe 108 extends to the upper end of one side of the treatment tank 101, and the upper end of the sludge suction pipe 108 is sealed with a sealing cap. When cleaning the sludge or sediment that has settled after long-term use, the sealing cap is opened, and the external sludge suction device is connected to the sludge suction pipe 108 to facilitate the extraction of the sludge deposited inside the sludge collection hopper 107. The sludge collection hopper 107 has a funnel-shaped structure, which facilitates the collection of sludge and improves the discharge efficiency.

[0022] A through hole 204 is provided near the lower end of the baffle plate 202, and pin plates 205 are rotatably installed on both sides of the baffle plate 202. The pin plates 205 are located on both sides of the through hole 204 and are arranged in a vertical array. The sewage treatment plate 203 is located inside the through hole 204. The through hole 204 facilitates the installation of the sewage treatment plate 203. During installation, the pin plates 205 are rotated first to engage the sewage treatment plate 203 inside the through hole 204. Then, the pin plates 205 are rotated to limit the position of the sewage treatment plate 203, facilitating installation and replacement. When using the cover plate assembly 2, external hoisting equipment is used to hoist the cover plate assembly 2 onto the tank body assembly 1, facilitating the installation of the cover plate assembly 2. For easy installation and assembly, a first air inlet pipe 206 and a second air inlet pipe 207 are fixedly installed on both sides of the upper end of the cover 201. A shut-off valve 208 is fixedly installed on one side of both the first air inlet pipe 206 and the second air inlet pipe 207. By opening the shut-off valve 208 at the corresponding position, it is convenient to ventilate the front or rear end of the treatment tank 101, and to allow different gases to be introduced according to different sewage treatment plates 203. When using aerobic microbial packing material for the sewage treatment plate 203, oxygen is supplied through the air pump 209 to increase the oxygen content inside the treatment tank 101. When using anaerobic microbial packing material for the sewage treatment plate 203, non-oxygen gas or air is introduced to reduce the oxygen content, facilitating microbial reproduction. The first air inlet pipe 206 and the second air inlet pipe 207 are fixedly installed on both sides of the upper end of the cover 201. The positions of pipe 206 and the second air inlet pipe 207 facilitate adjustment of the ventilation position. The wastewater treatment plate 203 is located below the baffle plate 202. Therefore, after gas is introduced, the pressure balance at both ends of the treatment tank 101 is broken, facilitating the flow of wastewater. The lower end of the first air inlet pipe 206 is close to the inlet pipe 102, and the lower end of the second air inlet pipe 207 is close to the outlet pipe 103. The first air inlet pipe 206 and the second air inlet pipe 207 are connected. When gas is introduced into the treatment tank 101 through the first air inlet pipe 206, the wastewater flows faster towards the outlet pipe 103. When the outlet pipe 103 is sealed and air is introduced through the second air inlet pipe 207, the wastewater flows more rapidly within the treatment tank 101. The wastewater is backflowed, and when the wastewater treatment plate 203 is used as a filter plate, the backflow of wastewater backwashes the impurities attached to the wastewater treatment plate 203, which facilitates the sedimentation of impurities inside the sludge collection hopper 107, improves the subsequent filtration effect, and avoids clogging. An air pump 209 is fixedly installed on one side of the upper end of the cover 201. The air outlet of the air pump 209 is connected to the first air inlet pipe 206 and the second air inlet pipe 207, and the air outlet of the air pump 209 is located in the middle of the two shut-off valves 208. The air pump 209 facilitates the supply of air to the inside of the first air inlet pipe 206 and the second air inlet pipe 207, and the shut-off valves 208 facilitate the switching of the air supply status of the first air inlet pipe 206 or the second air inlet pipe 207, making it convenient to use.
