Intensity meets requirement.
Filled layer stacks, and makes sewage flow through systems at different levels from top to bottom by gravity, is drained by interlaced arrangement
The position of mouth and injection point, reasonably optimizing hydraulic flow state prevent short stream and blocking, increase the discharge area of system, reduce wetland
The occupied area of system improves the treatment effeciency of system.Meanwhile stacking cloth and postponing, it is able to achieve miniaturization, it is wet convenient for indoors artificial
The arrangement on ground.
The homogenization of water flow after discharge outlet and injection point are staggered is realized in the arrangement of two opposite edges or midline position,
Situation is unevenly distributed in filled layer to reduce sewage on the basis of less discharge outlet and waterflood-transmission line is arranged.
The setting on water distribution slot weir, convenient for the conveying of water flow and the manual inspection of water flow.
Lightweight biological ceramic particle has good microorganism adsorption performance, and main purpose is a large amount of microbial floras of attachment, goes
Except the organic matter and suspension particulate matter in sewage, while to guarantee that stable structure, the density of biologic packing material are smaller.It rockfills
Material is that the ammonia nitrogen of absorption is absorbed and gone by the ammonia nitrogen in zeolite properties absorption effluent, then by the microorganism of attachment
It removes.Steel slag filler is can to effectively remove total phosphorus concentration using the total phosphorus in metallic element absorption effluent in steel slag.It is finally reached
Remove the purpose of the pollutants such as organic matter, suspended matter, the nitrogen phosphorus in sewage.
The gradient of water-stop sheet setting is 0.5-1%, it is ensured that waterpower flowing is more smooth, while avoiding filled layer necessity thickness
It is excessive.
Gap is convenient for plant growth and crosses water oxygenation.The short strain of the short stem of the plant of plantation, well developed root system, in addition to enhanced sewage
Outside treatment effect, the landscape effect for improving sewage disposal system and removal foul smell function can also be played.Sewage is flowed to from higher level
During junior, when by intermediate vegetation, reoxygenation can be carried out by way of gravity-flow ventilation, keeps oxygen concentration in sewage, is realized
The efficient degradation of organic pollutant.
Supported rod erecting is welded and fixed with ground built-in fitting, can ensure that supporting & stablizing, does not topple.
The setting of filler frame keeps the shape of filled layer, filler is avoided to be lost.
The beneficial effects of the invention are as follows the advantages for combining traditional artificial wet land system, can be effectively to dirty water pollutant
It is degraded and is removed, have occupied area small, effects of purification quality is high, is not easy to plug, the good advantage of hydraulic flow state is being handled
Construction cost can be greatly reduced when sewage.
