In this few large regions district, three-dimensional plantation comprehensive soil pick-up ability is stronger, purification comprehensively endures water herbaceous plant and submerged plant, and by the mating reaction of the microorganism in bed mud and water and hydrocoles (as plantation Gorgon fruit, eel grass, hornwort, lotus, power flower again, wild rice stem, Canna generalis Bailey, mullet grass, reed, water lily, Spiked Loosestrife, arrowhead, cattail, calamus, yellow flag, Arundo donax, water caltrop, black algae, waterweed, the waterplant such as Herba potamogetonis distincti, fish can be utilized simultaneously, shrimps, shellfish, the zoobenthos such as snail), fast degradation pollutant in water.Simultaneously, the organic tissue's body be not easily absorbed by plants in water, can be filtered by wetland soil and be trapped in soil, the inorganic salt and gas that are easily absorbed by plants are decomposed into by the microorganism in soil, thus the chemical pollutant in removing water body, allow soil coordinate root system of plant, utilize wetland soil to tackle and sedimentation suspended substance in water.
Multifunctional ecological purifying area is divided into A district and B district two large regions, each floor space 454m
2, 412m
2.This region arranges the lattice guest cage be made up of the natural zeolite of particle diameter 20-50mm and the gravel of particle diameter 50-100mm and is assembled into the high zeolite beds of 1.8m and gravel bed filters the sewage flowed through, adsorbs; Zeolite beds and gravel bed accessory have good nitrogen removal performance, and its filler natural zeolite and gravel have good Selective adsorption to ammonia nitrogen, make again it have good shock resistance to ammonia nitrogen.
Oxidation pond surface is provided with aeration and mechanical ventilation device and can be aerobic bacteria and provide dissolved oxygen.Attached growth of microorganisms is on the direct contact membranes surface of oxygen flow tubular fibre, sewage is when oxygen permeable film ambient dynamic, pollutent in water body enters in microbial film under the effects such as concentration difference driving and microorganism adsorption, utilized by microorganism through biological metabolism and propagation, make the pollutent in water body assimilate into microbial cells be fixed on microbial film or resolve into inorganic metabolism product, thus realize the purification to water body.This is a kind of ecological water treatment technology of artificial-strengthening, and water body can be made to form the self-purification aquatic ecosystem possessing self-regeneration function of a circulation.The scavenging process of its flow channel type is adapted to flowing waters especially and administers, and having conventional water treatment technology cannot technical superiority, engineering advantage, cost advantage and operational management advantage when.It is applied, and by making the improvement of water realize low cost, high-level efficiency, safe and sustainable, makes water body really become a beautiful landscape line.
The Xihe River, pool reuse water plant tail water Wetland ecological demonstration project consider dissimilar Ecological Disposal unit to pollutant removal feature after, reuse water plant tail water Wetland ecological demonstration project " WOPM multistage coupling High-efficient Water advanced treatment system " ecological wetland purification strategy, between the combination of integrated use dissimilar treatment process, higher pollutants removal rate and free water surface wetland can realize the feature of the automatic reoxygenation of water body, give full play to it to COD
mnwith the removal efficiency of ammonia nitrogen; By reasonably screening configuration waterplant, the absorptive function that in Appropriate application surface current artificial wetland, plant is continual and steady to nitrogen, phosphoric.Considering that tail water wetland influent quality may increase higher than sewage drainage standard one-level A standard, amount of inlet water short period of time causes wet land system cannot reach this several risk of theoretical contaminant removal efficiency with the tiny error in practice of construction, and demonstration project increases the enhancements such as the direct contact membranes of tubular fibre; Pollutent measuring and calculating is carried out with reference to " wastewater treatment engineering legislation HJ 2005-2010 " pollutent minimum removal theoretical efficiency value.The results are shown in Table 1-table 4.
