Be provided with water inlet in the position of vermiculite packing layer on the water distribution board, be convenient to water distribution evenly, be beneficial to winter operation and reduced soil and ooze with the following of current.
The bottom of water eliminator is provided with mudhole in the position of net packing layer, and water flows into water reservoir in case be untreated completely.
Stuffing frame is made up of support bracket and bracing frame two portions, and support bracket is connected the upper end of bracing frame, respectively in order to support lodge net filler and playing a supportive role.Hardware filler support net is set on the support bracket, and with support vermiculite packing layer, its net footpath should be less than the vermiculite particle diameter, in case vermiculite falls.
The earth that fetches earth is that rural area soil and the peat composed of rotten mosses are with 3: 2 mixed gained of mass ratio, so that plant-growth reduces under the soil and oozes in the soil packing layer.The net filler adopts discarded sunshade net, safety net, fishing net etc., utilization of waste material.
During operation, the sewage in the tank is flowed into by the water inlet on the water distribution board, through soil packing layer, vermiculite packing layer and software net packing layer, under wetland plant and action of microorganisms, sewage is effectively handled.Flowing into catch basin through water eliminator discharges.
Characteristics of the present utility model are the multiple guarantee of multiple design, in case wetland stops up efficient high-quality disposing of sewage.On wetland makes up, adopt the software and hardware filler and, be main stuffing with discarded sunshade net, safety net, fishing net with, multidimensional cloth.Unique software cloth has increased the current transmitance, and its huge surface area, helps biofilm development, has strengthened wastewater purifying efficiency, further guarantees not have to stop up.
