Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] see figure 1 , an embodiment of a biochemical enhanced processor of the present invention, the shell 4 of the biochemical enhanced processor is made of a steel plate with a certain thickness (such as: carbon steel plus glass fiber reinforced plastic or stainless steel) to make a circular cylinder, the upper part is cylindrical, and the lower part It is conical and supported by a base. Ozone generating equipment and iron salt dosing equipment are arranged outside the housing 4 of the biochemical enhancement processor.

[0023] A support frame 6 is set in the lower part of the housing 4 , and a central cylinder 14 is arranged in the middle of the housing 4 . The central cylinder 14 is equipped with biological fillers 13, the biological fillers 13 are sheet-shaped composite fillers, each sheet-shaped composite filler is formed into a string of biologic...

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...
