After the wetland plant kind was good, intermittent water inflow kept the bed body moistening, so that institute's kind of plant survives fast, regulates flooding velocity and stability thereof simultaneously, is adjusted to flooding velocity and is stabilized in 6 ± 0.5m
3/ d (being about 4.2L/min), all plants substantially all survived in 6～28 days, stopped into water, and allowed a body drop do
,Compound bio vermiculite modular system can normally use.
In the present embodiment, the long 2.2m of pond body, the wide 0.8m of one-level wetland 1, secondary wetland 2 and three grades of wetlands 3, dark 1.0m.
In the present invention, vermiculite be a kind of natural, nontoxic, under high temperature action dilatable mineral substance, belong to silicate, its crystalline structure is oblique system, from the appearance, it is as mica.Vermiculite produces when being certain grouan hydration, and its general and asbestos produces simultaneously.Because vermiculite has the ability of ion-exchange, it has great effect to the nutrition of soil.China's vermiculite is distributed more widely, is distributed in China the north more, mainly contains provinces and regions such as Xinjiang, Hebei, Inner Mongol, Liaoning, Shanxi, Shaanxi, in Sichuan, also there is distribution in province such as Henan, Hubei and Gansu.
Material selection principle of the present invention is: vermiculite is selected natural vermiculite for use, and the vermiculite material of the optional common mining industry process plants of used natural vermiculite is unscreened primary mineral of vermiculite; The zonal soil that red soil selects for use China middle subtropical zone humid region to distribute, it belongs to the red bauxite of moderate desiliconization allitization, and principal character is organic few, lacks basic metal and alkaline-earth metal and is rich in iron, aluminum oxide, is acid red, and degree of base saturation is low; The particle diameter of thin river sand is 1mm～5mm, and organic content is few.
The present invention with the soil nutrient characteristic that takes full advantage of vermiculite, the utility value that reduces floor space, avoid module layer to silt, increase the wetland oxygen level up and improve wetland plant is design concept, set up one novel three grades and fall streaming compound bio vermiculite module current wetland, water flow mode is the wave form that goes out on enterprising, this compound bio vermiculite module under higher hydraulic load (l.0m
3/ m
2.d) still can keep treatment effect preferably, to total clearance of each pollutent in the sewage more than 65%, effluent quality reaches secondary discharge standard substantially, if with its processing unit as artificial wet land system, then can improve the processing efficiency of wet land system greatly.In addition, vermiculite can increase the nutritive ingredient of soil, is conducive to the constructed wetland plant growth, for artificial swamp benign cycle in cities and towns provides condition.
