Abstract
The utility model relates to a kind of artificial swamp utilizing matrix grating and rinse control blocking, it is characterized in that: on the basis of conventional levels drowned flow artificial wet land, the leading portion distance blocked often is there is according to horizontal drowned flow artificial wet land, Wetland Substrate bed is divided into two portions, the lower left Large stone matrix of feed-water end side and the upper right side small particle size matrix of side, water side.The line of delimitation of two kinds of particle diameters arranges washpipe, and its percentage of open area near Large stone matrix side is greater than near small particle size matrix side.The utility model is distributed by particle diameter and rinses, and can not reduce on the basis for the treatment of effect, effectively delay and prevent the blocking of artificial swamp, extends artificial swamp work-ing life.
Description
Technical field
The utility model relates to technical field of sewage, particularly relates to a kind of artificial swamp utilizing matrix grating and rinse control blocking.
Background technology
Artificial swamp is that a kind for the treatment of effect is good, profitable on ecology, the sewage disposal technology that running cost is low, and particularly horizontal drowned flow artificial wet land (HSF) sanitary condition is good, is most widely used.But the blockage problem of HSF drastically influence the work-ing life of HSF, the method of solution artificial swamp blocking the most frequently used at present stops not crop rotation, although this method effect is better, certain porosity can be recovered, but existence two is pointed out inadequate, one is stop not crop rotation to need other wetland to replace its operation to dispose of sewage, and can increase floor space and construction cost like this; Two is blockings that this method can only solve biotic factor and causes, and can not solve the blocking that inorganics causes.Its blocking of HSF is mainly betided within the scope of several meters of feed-water end, drastically influence the overall performance of HSF.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of artificial swamp utilizing matrix grating and rinse control blocking.
Of the present utility modelly to be characterised in that: on the basis of conventional levels drowned flow artificial wet land, the leading portion distance blocked often is there is according to horizontal drowned flow artificial wet land, Wetland Substrate bed is divided into two portions, the lower left Large stone matrix of feed-water end side and the upper right side small particle size matrix of side, water side, the line of delimitation of two kinds of particle diameters arranges washpipe.
The leading portion distance that horizontal drowned flow artificial wet land often occurs to block, by decisions such as matrix particle diameter, influent quality and hydraulic loads, is generally 3 ~ 6m.
Lower left Large stone matrix and the marginal angle of inclination of small particle size matrix, upper right side are 15 ° ~ 45 °, often there is the point of interface of leading portion distance and the Wetland Substrate bed bottom blocked for turning point, to water inlet lopsidedness.
The washpipe that two kinds of particle diameter matrix line of delimitation are arranged, its percentage of open area near Large stone matrix side is greater than near small particle size matrix side, and is at least 2:1.
Compared with prior art, the beneficial effects of the utility model are: can rinse the tamper in matrix pores, can solve the blocking of wetland; Lower left matrix particle diameter is large, and porosity is large, can delay Wetland clogging and be easy to rinse; Upper right side matrix particle diameter is little, can ensure treatment effect; Washpipe is pressed certain angle and is tilted to install, and can strengthen developing result.
Accompanying drawing explanation
Fig. 1 is the facade view of the utility model horizontal drowned flow artificial wet land.
Fig. 2 is the orthographic plan of the utility model horizontal drowned flow artificial wet land.
Fig. 3 is the perforate figure of the utility model washpipe.
Primary clustering nomenclature in accompanying drawing: 1 inlet channel; 2 water inlet perforated walls; 3 inlet valves; 4 lower left Large stone matrix; 5 flowing water Valves; 6 upper right side small particle size matrix; 7 water outlet perforated walls; 8 outlet canals; 9 flush out penstock; 10 washpipes; 11 rotatable elbows; 12 rinse inlet valve; 13 top layer matrix.
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.
Planting plants in top layer matrix 13.
During sewage disposal, open inlet valve 3 and flowing water Valve 5, close and flush out penstock 9 and rinse inlet valve 12.Sewage, through inlet valve 3, enters inlet channel 1, and the sewage in inlet channel 1 enters in Wetland Substrate bed through water inlet perforated wall 2, and wetland lower left Large stone matrix 4 can delay Wetland clogging, and upper right side small particle size matrix 6 can ensure wetland variation effect.Effluent stream, after Wetland Substrate bed, through water outlet perforated wall 7, enters outlet canal 8, is finally discharged by flowing water Valve 5.Rotatable elbow 11, can be arranged in outlet canal and also can be arranged on outside outlet canal, is used for regulating the liquid level in Wetland Substrate bed, to ensure the depth of water needed for the utilization ratio of Wetland Substrate bed and plant-growth.
During flushing, close inlet valve 3, open and flush out penstock 9, rinse inlet valve 12 and flowing water Valve 5.Washpipe 10 is arranged in the line of delimitation surface thereof of Large stone matrix 4 and small particle size matrix 6.Wash-down water enters through rinsing inlet valve 12, and after washpipe 10 water distribution uniformity, enter Wetland Substrate bed and clean it, the water after cleaning enters inlet channel 1 and outlet canal 8, finally by flushing out penstock 9 and flowing water Valve 5 is discharged.
If inlet valve 3 has been arranged on inlet channel lowermost end, then can save flushing valve 9.
