Embodiment Construction

[0012] Such as figure 1 As shown, the sewage treatment device includes a water inlet 1, a control valve A2, a tee pipe 3, a water distribution pipe 4, a water hole 5, a bionic filler 6, a water receiving pool 7, a sewage return pump 8, a return pipe 9, and a solid-liquid separation tank 10. Mud outlet 11, control valve B12, water outlet 13, control valve C14.

[0013] When the device is working, the sewage enters from the water inlet 1, and the aperture of the water inlet 1 is larger than the aperture of the water outlet 13. The inflow flow is controlled by the control valve A2, and then the sewage enters the water distribution pipe 4 with a diameter of 50-100 mm, from the water distribution pipe 4. The water flows out slowly from the water hole 5, and 4 to 10 water holes 5 are set. The sewage flows down from the top to the receiving pool 7 along the bionic filler 6. 20% to 30% of the sewage is submerged below the water surface of the receiving pool 7, and 70% to 80% are expo...

Abstract

The invention discloses a bionic filler sewage treatment device, and belongs to the field of sewage treatment equipment. The device comprises a water distribution pipe, a bionic filler, a water receiving tank, a sewage reflux pump and a solid-liquid separation tank, wherein flow valves are arranged at a water inlet, a water outlet and a sludge outlet of the device. The bionic filler is verticallyarranged between the water distribution pipe and the water receiving tank, 70%-80% of the bionic filler is exposed in the air, and a biological membrane in the bionic filler directly utilizes oxygen in the air to carry out biochemical reaction through water distribution of the water distribution pipe, so that the aeration operation cost is saved; wherein the solid-liquid separation tank is connected with the water receiving tank, the water receiving tank is arranged above the ground, and the solid-liquid separation tank is partially arranged under the ground. According to the invention, biochemical reaction and reflux measures are used for cyclic purification of sewage, the device can process sewage with a relatively high pollutant concentration, the results of tests show that 80% of COD can be degraded, the operation cost is low, the structure is compact, the operation is convenient, and the treatment effect is remarkable.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to a bionic filler sewage treatment device. Background technique [0002] The biomimetic packing bed purification process belongs to the artificial biomimetic ecological biofilm restoration technology. It is a biofilm carrier technology that uses bionic fillers that are resistant to acid and alkali, milk pollution, and strong flexibility, which is conducive to the formation and regeneration of biofilms. Customer service The drawbacks of traditional aquatic plants being severely restricted by polluted water bodies greatly improve the effect of sewage treatment. Biofilm technology has been widely used in the treatment of heavily polluted rivers. It can effectively degrade COD, N and P in water bodies, eliminate black odor, and increase the concentration of dissolved oxygen. Compared with the activated sludge method, biofilm technology has the advantages of conven...
