Embodiment Construction

[0017] In order to better understand the technical solutions of the present invention, further description will be made below in conjunction with specific examples.

[0018] Such as figure 1 Shown, the embodiment of the present invention provides BioDopp biochemical reactor mixed liquid air lifting device, this mixed liquid air lifting device is made up of reactor bottom plate 1, reactor top plate 2, front baffle wall 3, rear baffle wall 4 , bottom diversion arc 5, top diversion device 6 and coarse hole aeration system 7. In this embodiment, a vertical mixed liquid flow channel is formed between the front baffle wall 3 and the rear baffle wall 4, and the coarse-hole aeration system 7 is arranged at the lower part of the vertical mixed liquid flow channel, under the front baffle wall 3. The top guide device 6 is arranged on the upper part of the vertical mixed liquid flow channel, and its bottom is flush with the upper edge of the rear baffle wall 4; the front baffle wall 3 is...

Abstract

The invention provides a mixed liquid air pushing device of a BioDopp biochemical reactor. The mixed liquid air pushing device is composed of a reactor bottom plate, a reactor top plate, a front flow baffle, a rear flow baffle, a bottom flow guide arc, a top flow guide device and a rough hole aeration system. Compared with an original mixed liquid air pushing device, the mixed liquid air pushing device of the BioDopp biochemical reactor has the advantages that the size is smaller, energy efficiency is higher, the flow state of mixed liquid is more scientific, and operating conditions are more stable; high-percent backflow of the mixed liquid under ultralow energy consumption is achieved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a mixed liquid air lifting device of a BioDopp biochemical reactor, belonging to the technical field of water treatment. Background technique [0002] BioDopp biochemical reactor is a sewage treatment device invented by Dr. Engelbart of German EBV company. It combines various single functional units (biological nitrification, denitrification, phosphorus release, phosphorus absorption, organic matter oxidation, precipitation, etc.) In the pond, and low dissolved oxygen (usually 0.3~0.8mg / L) is used to realize vertical synchronous nitrification / denitrification denitrification, and high sludge concentration (usually 5~8g / L) ensures efficient and stable treatment (low dissolved oxygen and High sludge concentration is the two major characteristics of its process). BioDopp biochemical reactor has the following advantages over existing traditional biochemical reactors: simple operation; hi...
