Abstract
The utility model relates to a kind of front bottom end aeration can back flushing artificial swamp, it is characterized in that: the bottom being easy to the fore-end blocked at horizontal drowned flow artificial wet land arranges aerating apparatus, adopt certain size grading simultaneously, front end particle diameter is less than rear end to shorten the distance of blocking, shorten the distance that aerating apparatus is set, feed-water end adopts perforated wall, and water side adopts perforated wall or perforated pipe.The beneficial effects of the utility model are: the method for back flushing of being intake by bottom aeration and water side, can reach good backwash effect, and front bottom end aeration can intensifying treatment effect, particularly denitrification effect simultaneously.
Description
Technical field
The utility model relates to technical field of sewage, and particularly relating to a kind of front bottom end aeration can back flushing artificial swamp.
Background technology
Compared with traditional second-stage treatment technology, it is low that artificial swamp has Construction and operation cost, power consumption is few, effluent quality is good, running maintenance is convenient, system configuration plasticity-is strong, to load variations strong adaptability, there are stronger organism, nutritive substance removal ability and ecological environment benefit significantly and can beautify the environment, realize the features such as waste water reclaiming, be widely used in processing polytype waste water, as sanitary sewage, acid mine drainage, agricultural effluent, urban storm, town and country landscape water, Petroleum Industry waste water and eutrophication water.
Can exist significantly not enough by artificial swamp, after running for some time, be easy to blocking, and blocking mainly occur in the front end of wetland.Artificial swamp process organism in there is stronger ability, but because of the aerobic environment of artificial swamp inside poor, lack the environment of applicable nitrobacteria growth, therefore the denitrification ability of artificial swamp is poor.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of front bottom end aeration can back flushing artificial swamp, strengthens nitrification effect by the mode of aeration, and aeration can make tamper suspend to be easy to be flushed away.
The technical scheme that the utility model adopts is: arrange aerating apparatus in the front bottom end of conventional levels drowned flow artificial wet land, adopt certain size grading to shorten the distance of wetland front end blocking simultaneously, feed-water end adopts perforated wall, water side adopts perforated wall or perforated pipe, back flushing water feed apparatus directly can adopt perforated wall or the perforated pipe of water side, also can arrange back-purge system separately.The front end of artificial swamp is less than the wetland of 15m for length, get wetland first three/mono-section, length is greater than to the wetland of 15m, first 1/4th sections that get wetland.The front end matrix particle diameter being provided with aerating apparatus is less than the matrix particle diameter of rear end.When wetland length is less than 15m, independent back-purge system can not be set, when wetland length is greater than 15m, independent recoiling device is set, and back-purge system be located at the end of aeration zone.
Compared with prior art, the invention has the beneficial effects as follows.
(1) at front bottom end aeration, the processing power of artificial swamp can be improved, particularly to the removal of nitrogen.
(2) front bottom end aeration, can make tamper suspend in water, be easy to be flushed away during back flushing, can solve the blockage problem of artificial swamp.
(3) front end particle diameter is little, can shorten the distance of blocking, shortens aerated space, cost-saving.
Accompanying drawing explanation
Fig. 1 is artificial swamp front view.
Fig. 2 is artificial swamp vertical view.
Primary clustering nomenclature in accompanying drawing: 1 inlet channel; 2 water inlet perforated walls; 3 inlet valves; 4 Large stone water distribution uniformity districts; 5 flowing water Valves; The 6 even catchment areas of Large stone; 7 water outlet perforated walls; 8 outlet canals; 9 flush out penstock; 10 rotatable elbows; 11 aeration section small particle size matrix districts; 12 Large stone matrix districts; Aeration tube bottom 13; 14 gas blowers.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Operation of the present utility model is divided into two main process: one is sewage treatment process; Two is flushing processes.
During sewage disposal, open inlet valve 3 and flowing water Valve 5, regulate rotatable elbow 10 to make liquid level in wetland adjust to the height wanted, close and flush out penstock 9.Sewage is through inlet valve 3, enter inlet channel 1, then enter in Wetland Substrate bed through water inlet perforated wall 2, again successively through Large stone water distribution uniformity district 4, aeration section small particle size matrix district 11, Large stone matrix district 12, the even catchment area 6 of Large stone, effluent stream is after Wetland Substrate bed, through water outlet perforated wall 7, enter outlet canal 8, finally discharged by flowing water Valve 5.Improve denitrification effect if want, according to demand, gas blower 14 can be opened in water inlet process, by bottom aeration tube 13 for wetland carries out aeration.
During flushing, close inlet valve 3, open and flush out penstock 9 and flowing water Valve 5.Wash-down water enters outlet canal 8 through flowing water Valve 5 and enters wetland bed layer by after water outlet perforated wall 7 water distribution uniformity, open gas blower 14 simultaneously, by bottom aeration tube 13 for wetland carries out aeration, tamper in wetland is suspended, wash-down water enters inlet channel 1 through water inlet perforated wall 2, discharges by flushing out penstock 9.
Claims (4)
1. a front bottom end aeration can back flushing artificial swamp, it is characterized in that: in horizontal drowned flow artificial wet land front bottom end, aerating apparatus is set, adopt certain size grading to shorten the distance of wetland front end blocking simultaneously, feed-water end adopts perforated wall, water side adopts perforated wall or perforated pipe, back flushing water feed apparatus directly can adopt perforated wall or the perforated pipe of water side, also can arrange back-purge system separately.
2. a kind of front bottom end aeration according to claim 1 can back flushing artificial swamp, it is characterized in that the front end of artificial swamp is less than the wetland of 15m for length, get wetland first three/mono-section, length is greater than to the wetland of 15m, first 1/4th sections that get wetland.
