Description

Energy-saving mud recycle device based on water pollution Technical Field The invention relates to the technical field of slurry recycling, in particular to an energy-saving slurry recycling device based on water pollution. Background In the fields of industrial production, municipal engineering and the like, the discharge and treatment of the muddy water are key links of environmental protection and resource recovery. If the pollutants such as organic matters, heavy metals, suspended floccules and the like contained in the slurry water are directly discharged, ecological problems such as water pollution, soil hardening and the like can be caused, so that the pollution risk can be reduced, the water resource can be saved, and the development requirements of energy conservation and emission reduction are met. At present, the biological treatment method is a mainstream technology of mud water purification because of the advantages of thorough pollutant degradation and less secondary pollution, wherein a treatment device taking a biological filter as a core is most widely applied, and the biological treatment method is used for realizing degradation of organic matters and toxic substances and interception of suspended matters by adsorbing microorganisms through a filter material to form a biological film. The existing biological filter slurry water treatment device mainly surrounds the fluidization state and the driving mode of a filter material layer to form two technical schemes, namely, a static filter material layer structure is adopted, filter materials are fixedly filled in the filter, slurry water permeates through the filter material layer from top to bottom by means of gravity and is matched with a single-aperture filter plate to achieve suspension interception, and the other scheme is adopted to solve the blocking problem of the static filter material layer, an aeration driving type fluidization structure is adopted, air flow is generated through a high-power aeration pump at the bottom to drive the filter materials to form semi-fluidization, and the contact between the filter materials and sewage is enhanced. Meanwhile, the filter material bearing structure of the existing device is mostly of an integral design, and the filter material is filled in the integrated filter cavity and needs to be integrally disassembled during maintenance. However, the above prior art still has many unresolved core drawbacks in practical application, and the specific disadvantages are as follows: firstly, the static filter material layer is easy to be blocked, the treatment efficiency is fast in attenuation, and the anti-blocking self-cleaning capability is lost In the existing static filter material layer device, suspended floccules and viscous sludge in slurry water are easy to adhere to the surface and pores of a filter material to form mud accumulation hardening, so that the pores of the filter material are blocked, the water flow resistance is increased rapidly, a filter material is required to be disassembled and cleaned after stopping for 7-10 days, the maintenance frequency is high, meanwhile, a biological film cannot be updated through physical friction in a static state of the filter material, the activity of an outer layer of an aged biological film is reduced and then is continuously adhered to the surface of the filter material, so that the degradation efficiency of organic matters and heavy metals is remarkably reduced along with the running time, the treatment efficiency is reduced after the long-term running, in addition, the water flow in the static filter material layer is in a laminar state, the sewage forms stable water film blocking on the surface of the filter material, the pollutants are difficult to diffuse into the biological film rapidly, the mass transfer efficiency is low, the treatment period is long, and the high-efficiency recovery requirement cannot be adapted. Secondly, the aeration driving type fluidization structure has high energy consumption, poor running stability and insufficient energy conservation In order to solve the blocking problem of the static filter material layer, the prior art adopts a high-power aeration pump to drive the filter material to fluidize, but the aeration energy consumption accounts for more than 60 percent of the total energy consumption of the device, and the ton water treatment energy consumption is as high as 0.8-1.2kWh, which is contrary to the development goal of energy-saving recovery, and the aeration intensity is difficult to precisely control, the filter material fluidization is insufficient when the intensity is too low, the local part is still easy to block, the filter material is severely collided and damaged when the intensity is too high, and a large amount of bubbles can impact the biological film to cause microorganism loss, thereby further reducing the treatment efficiency. In addition, the high-frequency noise generated in the aeration pro
