Abstract
The utility model relates to a sewage treatment apparatus with a swinging aeration head, belongs to the field of the environmental engineering, and in particular relates to a sewage treatment apparatus. The sewage treatment apparatus with the swinging aeration head comprises an apparatus outer housing (1) and a biologic carrier (3), and is characterized in that the sewage treatment apparatus increases a hanging chain aerating device (2) that comprises a floating drum (4), a distributing air hose (5), a balance weight (6) and an air diffusion film pipe (7), and the balance weight (6), the air diffusion film pipe (7) are together called the aeration head. The aeration head utilizes the self balance weight to sink into and close to the bottom of a pool, the aeration air enters the aerating device by the hose of the hanging aerating device, and enters the sewage in minute bubble form by a mipor rubber film, and has function of oxygen supply and agitation for the biologic carrier. The sewage treatment apparatus with the swinging aeration head of the utility model has stable treatment effect under the COD< Cr> 30 mg/ L, has strong shock resistance, is free from the temperature and the climate restriction, has small amount sludge generated, and is suitable for processing organic wastewater with low concentration.
Description
Technical field
The utility model belongs to field of environment engineering, particularly a kind of waste disposal plant.
Background technology
A kind of method of utilizing biological moving bed technology to dispose of sewage is arranged in the common waste disposal plant.The biological moving bed process program: reactor is the rectangle pond, adopts the suspending carrier filler, and this filler is sphere or the cylindrical pad of density between 0.7～0.96kg/L.The bottom, pond installs and fixes aeration head.In this technology, carrier provides the growing space for microorganism, grows microbial film on the carrier, and the dependence microbial film comes the pollutent in the degradation of sewage; Carrier moves in reactor, contacts with sewage, and sewage enters reactor from an end water-in, flows out from water outlet, and sewage need will reach certain residence time in reactor, guarantee treatment effect.
| Processing parameter | Support density | The carrier packing ratio | Gas-water ratio | The residence time |
| Range of choice | 0.7～0.96kg/ | 10％～67％ | 9～2 | 2～12h |
This technology is fit to low concentration sewage, process stabilizing, strong shock resistance very much; Operating subject matter is that aeration mode is a fixed form, and run duration carrier fluidization poor effect causes contacting with sewage insufficient, and biological activity is not high, influences treatment effect.
Summary of the invention
The present invention seeks to solve biological moving bed fixedly aeration mode in service run duration carrier fluidization poor effect, cause contacting with sewage insufficient, the problem that biological activity is not high promotes the development of technology of middle water recycle.
A kind of waste disposal plant of swinging aeration head that has, this device comprises device housings 1 and bio-carrier 3, it is characterized in that having increased in the waste disposal plant suspended chain aerator 2, suspended chain aerator 2 is made of floating drum 4, gas distribution flexible pipe 5, counterweight 6, air diffusion membrane pipe 7.
It is a kind of blast aeration equipment that is used for the aerobic section of biological process sewage disposal that the suspension chain type moves aerating apparatus, it is made up of gas distribution flexible pipe that swims in the water surface and the aeration head that is hung under the gas distribution flexible pipe, aeration head utilizes self counterweight to sink near the bottom, pond, the aeration air enters aeration head by the flexible pipe of suspended chain aerator, enter in the sewage by the form of mipor rubber film again, play to bio-carrier oxygen supply and stirring action with small bubbles.
Swing aeration and biological moving-bed equipment, shell can adopt cement structures, also can adopt steel plate or glass fibre reinforced plastic structure; Suspended chain aerator is conventional aerated product; Bio-carrier is selected sphere or the cylindrical pad of density between 0.7～0.96kg/L.
Swing aeration and biological moving-bed device is a rectangular shape, and different according to treating water flow Q and water quality are selected different volumes.
As water quality treatment COD
CrDuring≤300mg/L, equipment configuration V=Q * 4h;
