Embodiment
In order to better understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the frame diagram of whole Sewage treatment systems: community's sewage 13 enters coagulation unit 15 after sewage network 14 is collected, by effective process of coagulation unit 15, sewage enters follow-up second-stage treatment unit 16 again ... N level processing unit, wherein N be greater than 2 positive integer, finally up to standard, discharge through water side 18.
As shown in Fig. 2, Fig. 3, this treatment system is in series by multi-stage treatment units, and every one-level processing unit is composed in series by an ecostagnation pool 10 and a horizontal drowned flow artificial wet land, and sewage flows into horizontal drowned flow artificial wet land through the ecostagnation pool 10.The ecostagnation pool 10 slightly does as required to optimize on the basis of pre-existing topography to build up, and its long-width ratio is 3:1-10:1, and the degree of depth is 50-100cm, avoids excessive excavation.Horizontal drowned flow artificial wet land main body comprises cloth water channel 2, undercurrent pond 12, braiding channel 8, and main material is concrete or cement laid stone masonry.1 is cloth water channel barricade, cloth water channel is provided with cloth water channel water-in 11 and horizontal drowned flow artificial wet land water-in 3, wherein cloth water channel water-in 11 is uniformly distributed in 5-20cm under the liquid level of the ecostagnation pool, intake under adopting liquid, effectively prevent upper strata floating matter and bottom settlings thing from entering in horizontal drowned flow artificial wet land the blocking causing filler, delay duration of congestion; Horizontal drowned flow artificial wet land water-in 3 is positioned at the top of planting soil 4 bottom and shallow-layer filler 6, ensures the oxygen level of sewage, promotes the carrying out of nitration reaction.Be followed successively by from top to bottom in the body of horizontal drowned flow artificial wet land pond: plant 5, planting soil 4, filler 6, wherein, plant is reed, cattail, calamus, Spiked Loosestrife, Canna generalis Bailey or wilson iris; Planting soil thickness 15-20cm; Filler is the one or any combination of rubble, building waste, cobble or blast furnace slag, thickness is 30-60cm, the particle diameter of filler successively decreases step by step in one, two, three processing unit, subsequent processing units and three stage treatment unit are consistent, one, two, three processing unit packing material size controls respectively at 50-80cm, 30-50cm, 10-30cm, also improves a lot while the time delaying filler blocking to contaminant removal efficiency.Inlet 7 is evenly arranged on the position of 5-10cm at the bottom of braiding channel, is the environment that the carrying out of the anti-nitration reaction of pollutent creates anaerobism or anoxic, meanwhile, prevents the mud of pond bottom sediments to flow in braiding channel 8.The elevation on drop weir 9 is a little less than the cope level of filler, and the water in braiding channel 8 falls into the next stage ecostagnation pool 10 by drop weir 9, and drop this step, carried out aeration effect to sewage, improves the oxygen level of sewage.Then second-stage treatment unit starts to process sewage, so circulates, final sewage qualified discharge.
