Abstract

The patent of the utility model relates to a reinforce denitrogenation perpendicular - horizontal undercurrent integrated constructed wetland, its characterized in that: the anterior segment is vertical -flow constructed wetland, and the back end is horizontal undercurrent constructed wetland, and the middle connection canal that is is equipped with the aeration pipe bottom vertical -flow constructed wetland, improve the rate of nitrification to the mode of intaking at 2 o'clock is adopted simultaneously in the jam that slows down the wetland, directly lets in horizontal undercurrent constructed wetland with partly sewage without vertical -flow artificial wetland treatment, for horizontal undercurrent constructed wetland provides the carbon source, improves the denitrification effect, alleviates vertical -flow constructed wetland's load simultaneously.

Description

A kind of strengthened denitrification is vertical-horizontal drowned flow combined artificial wetland
Technical field
The utility model patent relates to technical field of sewage, particularly relate to a kind of strengthened denitrification vertical-horizontal drowned flow combined artificial wetland.
Background technology
Artificial swamp compared to traditional Wastewater Treated by Activated Sludge Process sewage, the advantages such as have profitable on ecology, running cost is low, and operational administrative is simple.But in the work-ing life of artificial swamp, blocked problem restricted, and limits the development of artificial swamp to a great extent.
Artificial swamp can be divided into surface current artificial wetland, vertical subsurface flow wetland and horizontal drowned flow artificial wet land, wherein treatment effect is vertical subsurface flow wetland and horizontal drowned flow artificial wet land preferably, vertical subsurface flow wetland denitrification effect is good, but the ability of organics removal is more weak, the ability of horizontal drowned flow artificial wet land organics removal is strong, but denitrification effect is poor.For enhancement process effect, occurred multiple combined artificial wetland, vertical-horizontal drowned flow artificial wet land be one, but treatment effect still difficulty reach water outlet requirement, especially denitrification effect is poor.
Summary of the invention
In order to overcome the problems referred to above, the utility model patent provide a kind of strengthened denitrification vertical-horizontal drowned flow combined artificial wetland.
The technical scheme that the utility model patent adopts is: vertical subsurface flow wetland and horizontal drowned flow artificial wet land are combined, leading portion is vertical subsurface flow wetland, back segment is horizontal drowned flow artificial wet land, middle for connecting canal, vertical subsurface flow wetland be connected canal place and be respectively provided with a water-in, carry out 2 water inlets, the water inlet connecting canal place can provide carbon source for the denitrification in horizontal drowned flow artificial wet land, and bottom vertical subsurface flow wetland, be provided with aeration tube, can the processing power of enhanced system, the especially raising of nitrification effect.
Compared with prior art, the invention has the beneficial effects as follows: increase aerating apparatus bottom (1) vertical subsurface flow wetland, can rate of nitrification be improved, and the blocking of wetland can be slowed down; (2) adopt the mode of 2 water inlets, former for part water is led in the horizontal drowned flow artificial wet land of back segment by connecting canal, for horizontal drowned flow artificial wet land provides carbon source, improve denitrification effect, alleviate the load of vertical subsurface flow wetland simultaneously; (3) two kinds of wetland compound uses, can improve the comprehensive clearance of pollutent.
Accompanying drawing explanation
Fig. 1 is wetland sectional view.
Fig. 2 is wetland vertical view.
Fig. 3 is aerating pipelines schematic diagram.
Primary clustering nomenclature in accompanying drawing:
1 inlet valve; 2 cloth water conduit tubes; 3 water inlet pipe valves; 4 vertical subsurface flow wetlands; 5 aeration mains; 6 vertical subsurface flow wetland posticums; 7 water inlet pipes; 8 connect canal; 9 horizontal drowned flow artificial wet land prosopyles; 10 horizontal drowned flow artificial wet lands; 11 outlet canals; 12 horizontal drowned flow artificial wet land posticums; 13 adjustable water level discharging devices; 14 water distribution branch pipes; 15 aeration branch pipes.
Embodiment
Below in conjunction with accompanying drawing, the utility model patent is further illustrated.When disposing of sewage, inlet valve 1 and water inlet pipe valve 3 are in opened condition, part sewage enters water distribution branch pipe 14 by cloth water conduit tube 2, to intake after water distribution branch pipe 14 water distribution uniformity vertical subsurface flow wetland 4, through vertical subsurface flow wetland posticum 6 after process, enter and connect canal 8 and another part and enter after the sewage being connected canal 8 mixes through water inlet pipe 7 and enter horizontal drowned flow artificial wet land 10 by horizontal drowned flow artificial wet land prosopyle 9, outlet canal 11 is entered after treatment by horizontal drowned flow artificial wet land posticum 12, wetland is discharged finally by adjustable water level discharging device 13.
Vertical subsurface flow wetland 4 is provided with aerating apparatus, and air enters aeration branch pipe 15 through aeration main 5, after the even gas distribution of aeration branch pipe 15, enter vertical subsurface flow wetland 4, improve microorganism active and dissolved oxygen concentration, thus improve treatment effect, especially strengthen nitrification effect.And a part of sewage enter without vertical subsurface flow wetland 4 processes connect canal 8 mix with the water outlet of vertical subsurface flow wetland 4 after enter horizontal drowned flow artificial wet land 10, for the denitrification in horizontal drowned flow artificial wet land 10 provide abundance carbon source.When in water outlet during ammonia-nitrogen content height, improve treatment effect by increasing aeration; When in horizontal drowned flow artificial wet land 10 water outlet during nitrate content height, increase the sewage quantity that enters and connect canal 8 to improve treatment effect by tuning up water inlet pipe valve 3.
