Description

Waste water recovery treatment equipment for plate production Technical Field The invention relates to the technical field of viscose fiber wastewater treatment, in particular to wastewater recovery treatment equipment for board production. Background In the production process of plates (such as artificial plates, plywood, fiber plates and the like), a large amount of industrial wastewater with high suspended matters, such as wood dust, adhesives, chemical residues and the like and high COD is generated. If the wastewater is directly discharged without effective treatment, serious pollution to water environment is caused, and water resource waste is also caused. Therefore, the high-efficiency recovery treatment of the wastewater produced by the plate industry becomes the necessary requirement for sustainable development of industry, in the existing advanced treatment technology of industrial wastewater, a process combining catalytic oxidation and physical and chemical treatment is often adopted, for example, the patent with publication No. CN114436438B proposes a catalytic oxidation integrated reactor for treating viscose fiber wastewater, and the reactor achieves a certain effect in improving mixing efficiency, reducing medicament consumption and slowing down scaling by arranging a premixing zone, a catalytic oxidation zone, a pH adjusting zone and a terminal flocculation zone and matching with catalytic reflux, jet aeration and an anti-scaling component with stirring and ultrasonic cleaning functions, The existing anti-scaling assembly adopts a fixed stirring blade structure, while the surface is coated with anti-scaling corrosion materials, the position and the posture of the anti-scaling assembly are fixed, the self-adaptive fitting and adjustment cannot be carried out according to the scaling condition of the inner wall of a pipeline or the flowing state of waste water, and in the high-hardness and high-sulfate viscose waste water, scaling matters are easily accumulated in the gaps between the blades and the pipe wall to form dead angles, so that the scale cleaning effect and the mass transfer efficiency of a system are affected. Meanwhile, the system lacks a self-adaptive regulation and control mechanism based on medium states, wherein although the system is provided with medicament backflow and jet aeration functions, the operation parameters such as medicament adding amount, aeration intensity and flow rate control are mainly set by virtue of preset working conditions and artificial experience, the system lacks on-line sensing and feedback regulation capability for real-time properties of wastewater such as viscosity, pollutant load and flow rate change, and when the wastewater components fluctuate or the flow resistance of the system is increased due to scaling, the existing device cannot dynamically identify and regulate a treatment strategy, so that excessive medicament adding or insufficient reaction is easily caused, and the treatment effect and economy are influenced. The triggering of the cleaning and treatment actions depends on passive signals, namely the conventional cleaning means such as ultrasonic vibrators need to be periodically or manually triggered, and the cleaning means cannot form closed-loop linkage with the flowing state or scaling degree of the wastewater, so that the cleaning time is disjointed from the actual requirements, and not only can the cleaning be untimely, but also the energy and medicament waste can be caused. There is a need for a wastewater recovery treatment facility for board production to solve the above problems. Disclosure of Invention In order to solve the technical problems, the technical scheme of the invention is that the wastewater recycling treatment equipment for plate production comprises a treatment area, a variable pump, a booster pump, an electric switching valve, a connecting pipeline, a control cleaning device and a filter screen, wherein the treatment area is communicated through the connecting pipeline; The control cleaning device comprises a base block, wherein the base block is respectively provided with a triggering mechanism, an anti-scaling mechanism, a recoil mechanism and a liquid inlet mechanism, and is in threaded connection with a connecting pipeline; The trigger mechanism comprises a cylinder body, the cylinder body is installed in a first perforation that the base block was seted up, cylinder body and cylinder pole sliding connection, the cylinder body passes through the pipeline intercommunication with miniature air pump, cylinder pole upper end and rotating block transmission are connected, rotating block and anti-scaling mechanism transmission are connected, first relief valve is installed to the cylinder body lower extreme, the base block is installed and is triggered the piece, trigger piece and cylinder pole surface sliding connection are located install recoil clearance switch and slide rheostat on the cylinder pole of trigg
