Abstract
The utility model relates to a disc-type microporous aerator capable of generating jetting flow. The disc-type microporous aerator comprises a supporting disc and a diaphragm firmly covering on the supporting disc, wherein the diaphragm is provided with micropores; the supporting disc is a ring-shaped curved-surface disc body which is hollow in the center, and a circulating pipe vertically passing through the supporting disc is arranged at the central hollow part; during aeration, jet flow can be generated in the circulating pipe. The disc-type microporous aerator capable of generating jet flow is reasonable in design, simple in structure, convenient to use and capable of effectively solving the problem of that sludge inside an activated sludge tank and at the bottom of the aerator is accumulated. In addition, the disc-type microporous aerator can be flexibly applied, and multipoint backflow or water intake can be realized through different pipe connecting ways, so that the service efficiency is increased.
Description
Technical field
The utility model relates to a kind of waste disposal plant, especially a kind of aerator, specifically a kind of platy fine bubble aerator that can jet.
Background technology
At present, the plate-type aerator generally using generally only has diaphragm that bubble flow is upwards provided, in activated sludge tank sewage disposal, part active sludge sinks to aeration plate bottom, after causing mud to pile up, harden, reduced on the one hand active sludge cell system effective active sludge quantity, the difficulty that mud hardens and also causes pond body to safeguard on the other hand.The current air diffusion aerator that also has downward aeration, by zig-zag air distribution head and be with serrate diffusing cover to form, but the bubble cutting out belongs to air pocket, and oxygen utilization rate (generally only having 8-9%) is more much lower than microporous membrane aeration (general 20% left and right).Therefore, if can design, a kind ofly both can guarantee aeration efficiency, can alleviate the aerating apparatus that pool bottom sludge hardens again, will there is positive meaning to enhancing productivity and reducing maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of platy fine bubble aerator that can jet, can effectively overcome the deficiencies in the prior art, makes aerator produce jet effect, alleviates hardening of aerator lower region mud, and adjustable water quality.
The technical solution of the utility model is:
A kind of platy fine bubble aerator that can jet, comprise supporting disk and firmly cover the diaphragm on supporting disk, this diaphragm is provided with micropore, the annular curved surface disk body of hollow out centered by described supporting disk, Bing Gai center hollow part, one circulating tube that runs through described supporting disk is installed, can forms in aeration region jet.
Further, between described circulating tube and supporting disk, be provided with sealing-ring, circulating tube is closely connected with supporting disk.
Further, the length of described circulating tube is 40-100mm, and its length that is positioned at supporting disk top is 10-60mm, and the length that is positioned at supporting disk below is 10-20mm.
Further, described circulating tube is made by plastics or stainless steel.
Further, described circulation duct lower end also can connect subsequent disposal unit, to introduce the sewage of subsequent disposal unit.
Further, described supporting disk below is provided with an annular gas booking groove being connected with this supporting disk, and this gas booking groove is connected with a plurality of production wells of being located on supporting disk, and is provided with an air inlet port in its bottom, can join with inlet pipe.
Further, described gas booking groove is concentric with supporting disk.
The beneficial effects of the utility model:
The utility model is reasonable in design, simple in structure, easy to use, makes aeration region produce pressure difference, and at the bottom of drive pond, current form jet from bottom to top, effectively solves mud in pond and piles up problem.And, also can pass through different pipe-connecting modes, realize multiple spot and reflux or multipoint water feeding, improve service efficiency.
