The fillers are usually installed in a fixed manner and are immersed in sewage for a long time. Their main function is to provide an attachment carrier for microorganisms and to increase the contact area between sewage and microorganisms. However, this traditional fixed filler structure has limited treatment efficiency for sewage during operation, poor dissolved oxygen transfer effect in sewage, and low metabolic efficiency of microorganisms, especially in the case of high-load sewage treatment, it is difficult to achieve the purpose of efficient degradation of organic matter.

[0003] Another problem with the traditional hydrolytic acidification reaction tank is that the surface of the fixed fillers is prone to accumulate suspended solids and particulate matter. Over time, the surface of the fillers is gradually clogged, not only reducing the contact area between sewage and microorganisms, but also affecting the smoothness of sewage flow. The occurrence of the clogging problem not only reduces the operating efficiency of the system, but also increases the maintenance frequency and operating cost of the fillers. At the same time, the traditional filler design is mainly fixed installation, lacking dynamic movement function, the flow state in sewage is mainly laminar flow, lacking enough turbulent flow, resulting in poor mixing effect of sewage and fillers, and low degradation efficiency of organic matter in sewage.

[0028] The following is in conjunction with the appendix Figures 1-4 This invention describes a hydrolysis acidification reaction tank for wastewater treatment, provided by some embodiments of the present invention.

[0029] This utility model provides a hydrolysis acidification reaction tank for wastewater treatment, comprising: a reaction tank body 100, a circulation drive component 200, and several reaction beds 300.

[0030] The reaction tank body 100 is equipped with an inlet 110 and a separation tank 120. The inlet 110 is used to introduce wastewater into the reaction tank, and the separation tank 120 is located at the bottom of the reaction tank body 100 to separate sediment and water in the wastewater and discharge the waste. The separation tank 120 can achieve stratified sedimentation of wastewater through internal baffles, effectively avoiding interference from sediment in subsequent treatment processes and improving wastewater treatment efficiency.

[0031] like Figure 3 As shown, the circulating drive assembly 200 includes a frame 210, a transmission wheel 220, a drive motor 230, and a chain assembly 240. The drive motor 230 drives the chain assembly 240 to continuously circulate through the transmission wheel 220. The surface of the chain assembly 240 has a plurality of lifting lugs 241 evenly distributed, used to drive the reaction bed 300 to move up and down along the chain path.

[0032] like Figure 4 As shown, the reaction bed 300 includes a basket 310, a scrubbing chamber 320, a packing plate 330, and a connecting rod 311. The basket 310 is fixedly installed on the lifting lug 241 of the chain assembly 240. The scrubbing chamber 320 is provided inside the basket 310. The surface of the scrubbing chamber 320 is mesh-like, and its mesh aperture is smaller than the gap between the packing plates 330. This is used to differentiate the flow of water and prevent the water flow from directly washing the surface of the packing plates 330. At the same time, it intercepts large particles in the sewage from entering the gap between the packing plates 330, preventing particles from depositing and clogging the surface of the packing.

[0033] A plurality of filler plates 330 are fixed in the shower cabin 320 in a parallel arrangement, and the filler plates 330 are in a corrugated strip structure, which can provide an attachment carrier for microorganisms and increase the transfer efficiency of water flow disturbance and gas-liquid interface. Through the design of the corrugated structure, the filler plates 330 can significantly improve the contact area and oxygen transfer effect in sewage treatment.

[0034] One end of the connecting rod 311 is movably connected to the surface of the basket 310, and the other end is rotatably connected to the lifting lug 241. Through the circulation movement of the chain set 240, the basket 310 is driven to realize lifting movement, so that the filler plates 330 can alternately move in air and water, thereby significantly improving the dissolved oxygen concentration in the sewage and promoting the growth and metabolism of aerobic microorganisms.

[0035] In addition, the reaction tank body 100 is also provided with an aeration nozzle 400, as shown in Figure 2 The aeration nozzle 400 transports oxygen into the sewage through the air pump assembly, which is used to further increase the oxygen content in the sewage and improve the oxidation effect of the sewage.

At the same time, through the intelligent control of the driving motor 230, the energy consumption can be reduced, and the system operation cost can be reduced.

[0038] In further optimization design, the differentiation tank 120 is provided with a bottom sewage outlet, which can periodically discharge the sediments through an automatic sewage discharge device, so as to avoid the influence of sediment accumulation on the operation of the reaction tank. The opening time of the bottom sewage outlet can be automatically controlled by an intelligent sensor according to the sediment concentration in the sewage, thereby reducing manual intervention and improving the automation level of the system.

[0039] Technical effects

[0040] Through the above specific embodiments, the sewage treatment efficiency can be significantly improved. The corrugated structure design of the filler plates 330 in combination with the alternating movement in air and water improves the concentration of dissolved oxygen, optimizes the oxygen transfer conditions, promotes the metabolism of aerobic microorganisms, and effectively degrades organic matter in the sewage. The mechanical movement of the circulating driving assembly 200 breaks the laminar flow state in the sewage, forms a turbulent flow, enhances the contact efficiency of the sewage and the filler, and at the same time, the mesh structure of the shower cabin 320 further protects the filler plates 330, reduces the risk of particle blockage, and prolongs the service life of the filler bed. The design of the differentiation tank 120 improves the separation effect of the sewage sediments, and guarantees the efficient operation of the system.

[0044] The packing plate 330 in the reaction bed 300 moves up and down circularly and alternately, realizes the shuttling of the packing plate in air and water, increases the dynamic change of the gas-liquid interface, and optimizes the oxygen transfer rate.

[0045] The corrugated packing plate 330 provides an attachment carrier for microorganisms, and through the corrugated design, the contact area of the sewage and the packing and the water flow disturbance are increased, and the sewage treatment efficiency is improved. The mechanical movement of the circulating driving assembly 200 breaks the laminar state in the sewage, forms a turbulent flow, promotes the full contact of the sewage and the packing, and improves the mixing uniformity of the sewage and the microbial community. The aerobic microorganisms adsorb and metabolize the organic pollutants in the sewage on the surface of the packing plate 330, and realize the removal of the organic matter through the biodegradation process.
