Level matches somebody with somebody particle diameter between 5-8mm, laying depth 30cm；The common coarse aggregate of fine sand layer selection is commonly husky, and laying depth exists
10cm or so.
Described geotextile layer is acupuncture nonwoven geotextiles, specification 200-300g/m2。
Described adsorption of nitrogen plant is the water plant for having economic value of the suitable local growth such as wild rice, Gorgon euryale, water peanut.
Described alkali acid modified attapulgite ceramsite sintering method is as follows：After attapulgite original soil is pre-processed, and lime mixes
Close and carry out alkali modification, then add HCl to carry out acid obtained solid and be modified, by the modified same flyash of solid powder of acid, water glass
Glass is granulated after being mixed by a certain percentage, after obtained haydite is put into Muffle furnace calcining a period of time, you can obtains alkali acid
Modified attapulgite haydite finished product.
Beneficial effect acquired by the utility model is：
It is anti-that 1. processing procedure of the present utility model includes root system of plant absorption, filler physics, chemisorbed and microorganism
A variety of processing procedures such as nitrification, be combined with each other, and form microorganism-plant cooperated purification pattern, make pollutant process more efficient, together
When microorganism-plant cooperated purification pattern taken into account multiple pollutant (such as N, P, COD) processing procedure, while present treatment system
Water plant in system after maturation also has certain economic value, the utilization of resources after can gathering in, strengthens present treatment system
Applicability and continuation；
2. for the utility model in edaphon carries out denitrification process, denitrifying bacteria can be with water plant root system shape
Into microecosystem, promote denitrification, strengthen the removal effect to nitrogen, ensure the interception to polluter in agricultural run-off
Effect；
3. the utility model using alkali acid modified attapulgite haydite be used as filler, this is a kind of novel ceramsite, its with than
The advantages that surface area is big, production cost is low, applied widely, there is very strong adsorption capacity to phosphorus, while in agricultural run-off
The polluters such as nitrogen, COD also have certain adsorption effect, there is stronger interdiction capability to polluter in agricultural run-off；
4. the utility model is using the efficient phosphorus adsorption stuffing such as grading cobblestone, alkali acid modified attapulgite haydite, fine sand
Nitrogen, phosphorus Adsorption are carried out, can effectively intercept nitrogen in farmland, phosphorus enters river, reduction river water eutrophy with rainwash
