A bionic filler sewage treatment device

Abstract

The invention discloses a sewage treatment device comprising a bionic filler and belongs to the field of sewage treatment equipment. The sewage treatment device comprises a water distribution tube, the bionic filler, a water reception pond, a sewage reflux pump and a solid-liquid separation pond, wherein a flow valve is respectively arranged on a water inlet, a water outlet and a sludge outlet of the device; the bionic filler is vertically arranged between the water distribution tube and the water reception pond; 70-80% of the bionic filler is exposed in the air; a biological membrane in the bionic filler distributes the water through a water distribution tube and performs a biochemical reaction by oxygen in the air, so that the aeration running cost is saved; the solid-liquid separation pond and the water reception pond are connected to construct, the water reception pond is arranged above the ground and the solid-liquid separation pond is arranged under the ground. The sewage is circularly purified through the biochemical reaction and the reflux measurement, and the device is suitable for processing the sewage with relative high pollutant concentration. The experiment shows that 80% of the COD can be degraded, the device is low in running cost, compact in structure, convenient to operate and obvious in processing effect.

Description

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

Problems solved by technology

At present, most of the reports on biomimetic plant filler technology are in-situ restoration techniques, and the restoration of water bodies has the limitations of light pollution and shallow lakes, such as the disclosed patent "underwater artificial ecological lawn" (CN203173889U), "a slow-flow regenerated water River ecological restoration method" (CN102963974A), "a combined ecological floating island" (CN202988843U), "a bionic plant for purifying slightly polluted water bodies in rivers" (CN2769261Y). less effective
