Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a high-efficiency purification and treatment device for garden reclaimed water. Background Technology

[0002] With the acceleration of urbanization and the enhancement of ecological and environmental awareness, the demand for reclaimed water for landscaping irrigation and landscape water replenishment is increasing. Landscaping reclaimed water usually comes from the tailwater of domestic sewage or rainwater after preliminary treatment. Although its treatment requirements are lower than drinking water standards, it is still necessary to effectively remove impurities such as suspended solids, organic matter, and pathogenic microorganisms to meet irrigation water quality requirements, prevent pipe blockage, avoid the breeding of mosquitoes and flies, and prevent the generation of unpleasant odors.

[0003] In existing landscaping reclaimed water treatment processes, physical filtration is a crucial pretreatment step, used to remove large suspended solids, leaves, weeds, fibers, and settled sludge from the water. Cleaning debris from the filter or removing sludge deposits at the bottom typically requires shutting down the entire filtration unit or even the entire treatment system. This shutdown directly interrupts the wastewater treatment process, reducing not only the overall system efficiency and water reuse rate but also making it difficult to meet the continuous supply of reclaimed water required by landscaping projects. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, this utility model provides a high-efficiency purification and treatment device for garden reclaimed water.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency purification and treatment device for garden reclaimed water, comprising:

[0006] A primary filter, a water distribution switching tank connected to the primary filter, and multiple disinfection tanks connected in parallel to the water distribution switching tank;

[0007] The primary filter includes:

[0008] The filter box has a wastewater inlet at the top;

[0009] Multiple filter plates are arranged at an angle inside the filter box, with adjacent filter plates tilting in opposite directions. The filter plates are grid plates, and the pore size of the grid plates gradually decreases along the water flow direction.

[0010] A debris interception box is disposed on the side wall of the filter box, and the inlet of the debris interception box is connected to the lower end of the filter plate;

[0011] A sludge interception mechanism is installed at the bottom of the filter box, and the sludge interception mechanism is provided with an outlet pipe that is connected to the water distribution switching pool.

[0012] Preferably, the debris interception box includes:

[0013] The box body is fixed to the side wall of the filter box, and its opening communicates with the interior of the filter box;

[0014] An interception net is installed at the opening of the box body, partially obscuring the opening, with the lower end of the grid plate flush with the upper edge of the interception net;

[0015] The cleaning door is hinged to the housing and is equipped with a locking mechanism and a sealing rubber ring.

[0016] Preferably, the sludge interception mechanism includes:

[0017] The interception box has an opening at its upper end that connects to the bottom of the filter box, and a slot is provided on its waist side wall. Slide grooves are provided on the inner walls of the two sides of the interception box opposite to the slot.

[0018] A flow cut-off plate is inserted into the slide groove through the slot, and can slidably cut off the upper and lower parts of the interception box;

[0019] The first drain valve is located at the bottom of the interception box;

[0020] The water outlet pipe is located at the top of the interception box.

[0021] Preferably, the water distribution switching tank includes:

[0022] The pool is a cylindrical tank, with its side wall connected to the water outlet pipe, and several drain pipes connected to the disinfection pool are provided on its bottom side wall.

[0023] A tank cover is provided at the upper opening of the tank body, and the drain pipe switching device is provided on the tank cover;

[0024] The second drain valve is located at the bottom of the pool.

[0025] Preferably, the drain pipe switching device includes:

[0026] A servo motor is mounted on the pool cover, and the servo motor is equipped with a drive module and a reducer;

[0027] A drive shaft is connected to the reducer and extends into the pool body;

[0028] A pipe switching ring is concentrically arranged with the pool body and connected to the drive shaft through a bracket. The outer wall of the pipe switching ring is provided with a rubber ring, which slides and seals against the inner wall of the pool body. A circular hole is opened on the pipe switching ring that can be aligned with any of the drain pipes.

[0029] Several inductive proximity sensors are disposed on the pool cover. The inductive proximity sensors are aligned vertically with each of the drain pipes and correspond one-to-one. The distance of each inductive proximity sensor from the center of the pool cover is equal. A sensing rod is fixed at one end to the drive shaft and the other end is provided with the trigger of the inductive proximity sensor.

[0030] The sensing rod is aligned vertically with the circular hole on the pipeline switching ring.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] This invention features multiple grid plates tilted in opposite directions, with gradually decreasing pore sizes. This not only achieves multi-stage physical filtration and improves filtration efficiency, but more importantly, the tilted design allows intercepted solid debris (such as leaves, plastic bags, and fibers) to automatically slide down to the lower end of the plate surface under the influence of gravity and water flow. The inlet of the debris interception box is precisely aligned with the lower end of the filter plate, ensuring that the sliding debris falls into the box. The interception mesh partially covers the opening, effectively preventing backflow of debris without hindering its entry into the box. The debris interception box has a hinged cleaning door with a sealing rubber ring and locking mechanism, allowing operators to quickly clean accumulated debris at any time during normal system operation. This avoids the need to stop the entire filtration unit or even the entire wastewater treatment process to clean the filter surface.

[0033] The sludge interception mechanism, through its interception box and intercepting plate design, allows filtered fine particles and sludge to settle within the interception box. The intercepting plate is inserted into a chute via a slot. When sludge discharge is required, the intercepting plate is fully inserted, physically cutting off the upper and lower parts of the interception box. At this point:

[0034] Upper section: Wastewater continues to flow to the water distribution and switching tank through the upper outlet pipe, and the filtration and effluent discharge process is not affected.

[0035] Lower section: Sludge isolated below the interceptor plate can be safely discharged through the first drain valve at the bottom.

[0036] Resumption of operation: After the sludge discharge is completed, simply remove the baffle plate to restore the connection between the upper and lower parts of the interception box. The operation is simple and quick. Attached Figure Description
