Biochemical strengthening treater

Abstract

The invention provides a biochemical strengthening treater. The biochemical strengthening treater comprises a housing, a central barrel body, a supporting frame, a water distributor, biological fillers, an aerator, a water outlet slot, a water outlet tube, a water inlet tube, a chemical feed tube, a gas inlet tube, a sludge reflux tube and a sludge tube, wherein the central barrel body, the supporting frame, the water distributor, the biological fillers, the aerator, the water outlet slot, the water outlet tube, the water inlet tube, the chemical feed tube, the gas inlet tube, the sludge reflux tube and the sludge tube are arranged in the housing; the central barrel body is arranged on the supporting frame. The biochemical strengthening treater is characterized in that the biological fillers in the central barrel body are sheet-shaped combined fillers; each sheet-shaped combined filler is connected to be a string type biological filler by a nylon rope; and the string type biological fillers are vertically arranged at intervals. The aerator in the central barrel body is a tubular micro-pore aerator, and vertically arranged in gaps among the string type biological fillers. The biochemical strengthening treater disclosed by the invention is compact and reasonable in structure, capable of adopting a vertical aeration technology, high in oxygen charging efficiency, good in energy-saving effect and unlikely to block. The biological membrane process and the active sludge process are combined, biological oxidant, biological flocculation, biological strengthening technology, chemical coagulation and ozone oxidation treatment are organically combined, so that the outlet water quality is good and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a biochemical enhanced processor. Background technique [0002] Sewage biological treatment is a treatment method for purifying sewage by using the metabolism of microbes that are widely distributed in nature, have various types of metabolic nutrients, and have strong adaptability. Biological treatment technology is widely used because of its easy-to-obtain sources and various types of treatment subjects, especially aerobic biological treatment technology has the advantages of high BOD removal rate, high treatment rate, and thorough sewage purification, and has become the first choice for sewage treatment. subject to secondary processing. Therefore, the design and operation of aerobic biological treatment technology directly affects the success or failure of the entire treatment project. At present, there are many kinds of aerobic biological treatment technologies. In...

AI Technical Summary

Problems solved by technology

However, in the long-term engineering application practice, it is found that the conventional aerobic biological treatment technology has problems such as high energy consumption, large sludge production, easy clogging of the microporous aerator, high treatment cost, and difficulty in improving the treated water quality.
