Description
Technical field
The utility model relates to waste disposal plant.
Technical background
The sanitary sewage artificial swamp is handled bed and is mainly contained vertical current constructed wetland and handle bed and horizontal flow artificial wetland and handle beds two kinds.More than the vertical current constructed wetland bed height 100cm, usually adopt thinner matrix such as sand etc. as filtration media, sewage is handled obtaining in the downward vertical diafiltration process in top layer, and the plant great majority that it adopted are reed, cyperus alternifolius, Caulis Miscanthis floriduli, power grass, nutgrass flatsedge and Canna generalis Bailey etc. again.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, Scirpus tabernaemontani, iris and the calamus 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.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 handles bed accessory than horizontal flow artificial wetland better aerobic condition, and to BOD in the waste water
5All better with the removal effect of COD, but it is poor that the removal effect of SS is handled bed than horizontal flow artificial wetland; Though it is very capable to the nitration treatment of waste water, it is poor that its denitrification ability is also handled bed 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) two kinds of artificial swamps of vertical current and horizontal flow handle bed to the removal ability of phosphorus in the municipal effluent all relatively poor (＜30-40%), and matrix such as the sand of existing extensive employing, gravel are all shorter saturated work-ing life to the absorption of phosphorus, are generally 2～3 years; Handle the bed composition composite system that is together in series even horizontal flow artificial wetland is handled bed and vertical current constructed wetland, 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 an order by vertical current and horizontal flow and be composed in series combined artificial wetland processing bed, make full use of vertical current constructed wetland and handle bed and finish the major part of oxygen consumption organic and suspended substance is removed and nitrated fully to sanitary sewage, and utilize horizontal flow artificial wetland to handle bed and finish SS, COD and BOD
5Thorough removal, and finish by denitrification the major part of nitrogen removed; 2. the sub-fraction raw sewerage is directly entered horizontal flow artificial wetland and handle the bed head end, handle at horizontal flow artificial wetland under the anoxia condition of bed, utilize the organism in the sanitary sewage to finish the denitrification denitrogenation process as carbon source; 3. handle bed and horizontal flow artificial wetland at vertical current constructed 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.
Sanitary sewage vertical current-horizontal flow combined artificial wetland is handled bed: vertical current constructed wetland is handled bed and horizontal flow artificial wetland handle bed and be together in series, vertical current constructed wetland is handled bed preceding, horizontal flow artificial wetland handle bed after.Sanitary sewage at first after vertical current constructed wetland is handled the bed body processing of bed, is removed part SS, COD, BOD
5And carry out nitrification; Then handle bed gravity flow water distribution to the low slightly horizontal flow artificial wetland of physical features by the hydrostaticpressure of water collecting basin, utilizing horizontal flow artificial wetland to handle bed finishes organic thorough removal, and finish removal to nitrogen by denitrification, and make the part raw sewerage directly enter horizontal flow artificial wetland processing bed front end with supplementary carbon source, the removal effect of stream of improving the standard to nitrogen.Handle bed and horizontal flow artificial wetland at vertical current constructed wetland and handle and fill the high phosphorus adsorbing base in the bed, and handle plantation Lu Sheng flowers and fresh-cut flowers on the bed, planting vegetable on the tectum that horizontal flow artificial wetland is handled bed at vertical current constructed wetland.
Sanitary sewage vertical current-horizontal flow combined artificial wetland phosphorus removing method is the technical process that utilizes above-mentioned denitrogenation method, finishes the removal to phosphorus in the waste water in denitrogenation.Concrete grammar is: at first, in vertical current constructed wetland, fill the matrix blast furnace slag that phosphorus is had very strong power surely, and plantation Canna generalis Bailey, Chinese rose and rose, utilize blast furnace slag matrix and flower plant to remove most of phosphorus in the waste water; In horizontal flow artificial wetland, fill matrix such as marble or Wingdale and the cinder etc. that phosphorus had more strong power surely, and planting vegetable such as green water cress, water spinach (leading to) dish, leek, romaine lettuce, cucumber, tomato (cherry tomato), arrowhead and wild rice stem etc., utilize matrix and vegetables to remove a part of phosphorus in the waste water.
