Embodiment Construction

[0018] (1) Anaerobic treatment of sewage

[0019] The pretreated sewage enters the acidification-anaerobic zone 10 through the water inlet pipe 61, the water inlet valve 71, and the liquid flow meter 80, enters from the upper edge, forms a circular water flow and flows downward. The flow descends to the center of the lower conical bottom, and is connected to the center of the upflow conical bottom of the acidification secondary anaerobic zone 101 by the guide pipe 60 and then flows upward. Upflow to the upper part through the diversion port 12 and downflow. The downflow to the lower gathering tank 16 enters through the guide pipe 60 and enters from the upper edge of the anaerobic zone two mixer 50 . In order to prevent the operation from being affected by excessive water flow rate, a buffer plate 51 is provided on the upper end of the mixer 50, and an overflow hole 52 is opened in the center of the buffer plate 51 to buffer the water flow to ascend smoothly. The heavy part...

Abstract

The invention relates to a special diversion anaerobic baffled reactor, which has a plurality of advan-typetages, but is still in the experimental research period at home and abroad currently, and the relevan-typet engineering design and operation reports are extremely less. By aiming at the defect, the anaerobic baffle reactor is provided with a special diversion structure, so the large-scale sewage treatment requirement can be satisfied. The sewage anaerobic treatment is compared with the aerobic treatment, the power of about 90 percent can be saved, the amount of the survival residual sludge is only 10% of the aerobic treatment, the biochemical oxygen demand (BOD) removal rate can reach above 90%, the chemical oxygen demand (COD) removal rate is about 70-90%, most organics are converted into methane, and the special diversion anaerobic baffled reactor not only saves the energy but also produce the energy, and has a wide development prospect. The reactor is scientifically arranged and reasonably distributed, is dispensed with a triphase separator, is easy to control, is not blocked and has stable processing efficiency. The special diversion anaerobic baffled reactor can fully exert excellent features in the large-scale sewage water treatment field and can be practically applied.

Description

technical field [0001] The invention relates to a sewage anaerobic treatment engineering technology integrating chemistry, biology and environmental protection, in particular to a baffle type special diversion anaerobic reactor. Background technique [0002] Baffled anaerobic reactor (abbreviated as ABR) is suitable for treating high-concentration organic sewage. Due to its partition structure, the sewage is deflected up and down many times in the reactor, which strengthens the contact mass transfer between sewage and sludge, does not have a three-phase separator, and has many advantages such as no sludge clogging. But at present, it is still in the stage of experimentation and application research at home and abroad. There are few reports on engineering design and operation, and they have not reached the stage of large-scale practical application. Contents of the invention [0003] In view of the above-mentioned shortcomings, the present invention gives the baffled anae...
