Embodiment
Referring to accompanying drawing, the horizontal baffling compound type artificial wetland Sewage treatment systems, include the multistage surperficial flow pattern wetland lattice chamber 1 and the multistage undercurrent type wetland lattice chamber 2 of serial connection successively, be separated with divider wall 3 between each lattice chamber, the head end of flow pattern wetland lattice chamber, first step surface has sewage import 4, and it is connected with the relief outlet or the unitary end of other sewage disposals of sewage.The top that divider wall between surperficial flow pattern artificial swamp lattice at different levels chamber is crossed the water place is provided with overflow weir 5, and its corresponding middle and lower part offers many row's water holes 6; The top that divider wall between flow pattern artificial swamp lattice chamber, surface and subsurface constructed wetland lattice chamber is crossed the water place is provided with overflow weir 5; Divider wall between subsurface constructed wetland lattice at different levels chamber is crossed the Shui Chu middle and lower part and is had many row's water holes 6, and the undercurrent type wetland lattice chamber of last step is provided with water port 7; The wetland lattice at different levels chamber of serial connection is the horizontal baffling formula on the whole arranges, and the bottom surface of each wetland lattice chamber keeps about 1% longitudinal gradient.Plantation absorbs the floating plant that the pollutent ability is strong and have certain economic value on the water surface of surperficial flow pattern artificial swamp lattice at different levels chamber, as duckweed, Herba Eichhorniae etc.Subsurface constructed wetland lattice at different levels chamber can be selected the different wetland plant of plantation respectively according to seasonal variation, sewage quality feature etc., as Caulis Miscanthis floriduli, cyperus alternifolius, rye grass, Canna generalis Bailey etc.
Artificial swamp can divide ground surface flow pattern artificial swamp and subsurface constructed wetland by sewage flow pattern difference in wetland bed.Surface flow pattern artificial swamp: sewage is in wetland bed surperficial cross flow, and subsurface constructed wetland: sewage is seepage flow under wetland bed surface.
The artificial swamp of horizontal baffling compound type pattern, at first, the single artificial swamp mode reformation of tradition has been designed to comprise simultaneously the compound pattern artificial swamp of two types on surperficial flow pattern and undercurrent type in same artificial swamp, be that the front portion is divided into surface current type artificial swamp, directly be connected (when directly being connected with the relief outlet of sewage with the relief outlet or the unitary end of other sewage disposals of sewage, note being provided with grid device, filter and remove bigger suspended substance), the rear portion is divided into subsurface constructed wetland, is connected with the rear of the surperficial flow pattern artificial swamp of fore portion.Secondly, two types artificial swamp part is separated into a plurality of lattice chamber again respectively (according to the water quality characteristics and the actual field ground situation of sewage, adjust lattice chamber number, width and length), that the lattice chamber is is microscler (long-width ratio is greater than 2, and is wide 1～5 meter, dark 1～1.5 meter), be provided with divider wall between each lattice chamber, divider wall is crossed water section and is located at upper level lattice chamber end, and its width is W/2～W/3 (W: lattice chamber width), comprise two kinds of forms of overflow weir and water hole.Overflow weir is located at the top that divider wall is crossed water section, and height of weir plate is the h/2～2h/3 of wetland height; Water hole is located at the middle and lower part that divider wall is crossed water section, evenly be laid in h/5～h/2 (h: lattice chamber divider wall height) in the scope at the bottom of the pond, water hole perforation size, spacing and row's number depend on factors such as handling flow, water quality situation and hydraulic detention time, and the suggestion water hole total area is about 20% of a discharge section area (being the cross-sectional area that the divider wall end is provided with the water hole part).Water hole can adopt to be buried pvc pipe underground or directly offer forms such as perforation in body of wall in the body of wall.Enter next stage lattice chamber at the water hole and the overflow weir of surperficial flow pattern artificial swamp treating part sewage by divider wall from upper level lattice chamber; Then, the sewage overflow weir of crossing the water place by divider wall enters the 1st grade of subsurface constructed wetland from the surperficial flow pattern artificial swamp lattice chamber of last step and handles the lattice chamber; The water hole of crossing the water place at subsurface constructed wetland treating part sewage by divider wall enters next stage lattice chamber from upper level lattice chamber.Each lattice chamber is communicated with from beginning to end, connects in turn, therefore presents horizontal baffling formula plug-flow structure on the whole.Each lattice chamber of artificial swamp processing unit keeps 1% longitudinal gradient by water (flow) direction, and sewage can pass through from streamed, and each lattice chamber of flowing through is until finishing the entire treatment process.Pending sewage enters surperficial flow pattern artificial swamp part in the system through pvc pipe, h/3～h/2 at the bottom of pvc pipe buries to the degree of depth apart from artificial swamp reaction tank pond (h: artificial swamp reaction tank body of wall height), h/6～h/5 at the bottom of the water side pvc pipe buries to the degree of depth apart from artificial swamp reaction tank pond.
Sewage was generally 2～3 days at the hydraulic detention time of horizontal baffling compound type artificial wetland.The artificial swamp mesostroma also has very big influence to water treatment effect, and the composition of general substrate material mostly is composite shape matl.Matrix is placement in layers, every layer when filling longitudinal gradient and the artificial swamp pond at the bottom of longitudinal gradient be consistent.The gravel of laying particle diameter 2～5cm mainly plays intercepting padding material and suspended substance on the wide vertical surface of the about 20cm of end of the first and last end of undercurrent type wetland, the 1st grade of surperficial flow pattern wetland first section and last step surface flow pattern wetland.
The plant of being chosen seeds in the horizontal baffling compound type artificial wetland has bigger influence to wastewater treatment efficiency.Can be in horizontal baffling compound type artificial wetland according to the feature of seasonal variation, sewage quality, the different plant of in each compartment, choosing seeds respectively.The subsurface constructed wetland part of forwardly dividing can be chosen seeds and be absorbed floating plant such as duckweed, the Herba Eichhorniae etc. that the pollutent ability is strong and have certain economic value, the surperficial flow pattern artificial swamp part of rear section can choose seeds cattail, cyperus alternifolius, rye grass, Canna generalis Bailey etc.
Horizontal baffling compound type artificial wetland adopts brickwork construction, and carries out antiseepage and handle.
Can be in this improved horizontal baffling compound type artificial wetland according to the water quality characteristic and the actual field ground situation of sewage, the matrix that number, size and the each several part choosing of each lattice chamber in the size, subsurface constructed wetland part of the type of artificial swamp, surperficial flow pattern artificial swamp part and subsurface constructed wetland part fill out and the plant of seed selection are set neatly.
