Description
Technical field
The utility model relates to waste disposal plant.
Background technology
Municipal effluent artificial swamp treatment unit mainly contains horizontal flow artificial wetland and handles bed and vertical current constructed wetland processing bed at present.About 60～the 80cm of horizontal drowned flow artificial wet land bed height, adopt thick matrix such as gravel as treatment media, sewage is horizontal flow under the face of land of artificial swamp, and kind is implanted with large-scale emergent such as reed, cattail and the Scirpus tabernaemontani etc. that secrete the oxygen ability in hypothallus, utilizes the oxygen ability of secreting of waterplant to provide oxygen for the organic substance that the microbial film on the artificial swamp matrix decomposes in the sewage.More than the vertical current constructed wetland bed height 100cm, usually adopt thinner matrix such as sand etc. as filtration media, sewage is obtaining handling in the downward vertical diafiltration process in top layer, and the plant great majority that it adopted are reed, cyperus alternifolius and Caulis Miscanthis floriduli etc.The weak point that exists has: (1) horizontal flow artificial wetland is handled bed and is had shortcomings such as aerobic condition deficiency, though it can remove SS well, and also can remove some BOD.But it is bad to the removal effect of ammonia nitrogen usually.Because it can not finish the nitrifying process of most of waste water, even it has stronger denitrification ability, thereby can not independently finish two treating processess of nitrification and denitrification of waste water, to reach the purpose that denitrogenation of waste water is handled.(2) vertical current constructed wetland processing bed is stronger to the processing power and the nitrated ability of oxygen consumption organic in the waste water, and it has better aerobic condition than horizontal flow artificial wetland, and to BOD in the waste water
5All better with the removal effect of COD, but poor to the removal effect of SS than horizontal flow artificial wetland; Though it is very capable to the nitration treatment of waste water, its denitrification ability is also poor than horizontal flow artificial wetland, thereby can not finish two treating processess of nitrification and denitrification of waste water separately, to reach the purpose that denitrogenation of waste water is handled.(3) vertical current constructed wetland handle bed and horizontal flow artificial wetland handle beds two kinds artificial swamps to the removal ability of phosphorus in the municipal effluent all relatively poor (＜30-40%), and matrix such as sand of existing extensive employing, gravel is all shorter saturated work-ing life to the absorption of phosphorus, is generally 2～3 years; Even with horizontal flow artificial wetland and the vertical current constructed wetland composition composite system that is together in series, as still adopting sand, gravel matrix, its to the clearance of phosphorus still less than 60%.
Summary of the invention
The purpose of this utility model is: 1. two kinds of artificial swamps are handled the bed order by horizontal flow artificial wetland and vertical current and form combined artificial wetland, make full use of the horizontal flow artificial wetland removal ability good, alleviate SS in the waste water handles bed to vertical current constructed wetland blockage problem SS; Utilize horizontal flow artificial wetland to handle bed simultaneously and remove a part of COD, BOD
5And ammonia nitrogen; 2. utilizing vertical current constructed wetland to handle bed finishes the thorough removal of oxygen consumption organic and nitrated fully to municipal effluent; 3. the nitration treatment water outlet of vertical current constructed wetland being handled bed is back to horizontal flow artificial wetland by certain reflux ratio and handles the bed head end, handle at horizontal flow artificial wetland under the anoxia condition of bed, utilize organism in the municipal effluent to finish the internal carbon source denitrification denitrogenation process of the nitrated water outlet that refluxes as carbon source; 4. handle bed and vertical current constructed wetland at horizontal flow artificial wetland and handle in the bed and adopt high phosphorus adsorptive power matrix respectively, to reach the higher total tp removal rate and the purposes such as matrix work-ing life of length.
The municipal effluent combined artificial wetland is handled bed: horizontal flow artificial wetland and vertical current constructed wetland are together in series, and horizontal flow artificial wetland is preceding, vertical current constructed wetland after.Municipal effluent at first after the bed body of horizontal flow artificial wetland is handled, is removed most of SS, COD, BOD
5With the part ammonia nitrogen; Then the hydrostaticpressure by water collecting basin is to the low slightly vertical current constructed wetland gravity flow water distribution of physical features, utilizes vertical current constructed wetland to finish the thorough removal of oxygen consumption organic and remaining ammonia nitrogen is nitrated fully; Then the treat effluent of vertical current constructed wetland is back to the head end of horizontal flow artificial wetland in 50%～100% ratio with fresh water pump, utilizes the anoxia condition of horizontal flow artificial wetland and sewage is finished the treat effluent of backflow as carbon source denitrification denitrogenation process.In horizontal flow artificial wetland and vertical current constructed wetland, fill the high phosphorus adsorbing base, ST Stuffing Table soil tectum on matrix, and on the tectum of horizontal flow artificial wetland planting aquatic plants, plantation Lu Sheng flowers on the tectum of vertical current constructed wetland.
The municipal effluent combined artificial wetland is to utilize above-mentioned technical process, finishes the removal to phosphorus in the waste water in denitrogenation.Concrete grammar is: in horizontal flow artificial wetland, fill matrix such as marble or rhombspar and the Wingdale etc. that phosphorus had more strong power surely, and planting aquatic plants such as Scirpus tabernaemontani and cyperus alternifolius, utilize matrix and waterplant to remove a part of phosphorus in the waste water; Secondly, in vertical current constructed wetland, fill phosphorus is had the matrix of very strong power surely such as blast furnace slag etc., and plantation Canna generalis Bailey and cyperus flower, utilize blast furnace slag matrix and Lu Sheng flowers to remove most of phosphorus in the waste water; Then, along with the backflow of treat effluent, make wherein remaining phosphorus again by horizontal flow artificial wetland and vertical current constructed wetland, utilize effects such as matrix, plant and microorganism further to remove again, go round and begin again, reach municipal sewage plant's first discharge standard until the sewage total phosphorous.
