Abstract
A subsurface infiltration land treatment and constructed wetland treatment technology is a widely used technology in the current sewage treatment. The water pipe network distribution in the whole application engineering system is a key link. As the common subsurface flow type water distribution is not uniform and the operation is unstable, the system is easy to form short flow and blockage, thus greatly reducing treatment effect and efficiency of sewage. Aiming at the existing problems, the technology designs an inner-outer sheathing double-layer water distribution pipes; the sewage is immersed onto an ecological warm land filter bed after being distributed uniformly through a double-tube water distribution device, thus ensuring that the short flow impact is not formed in the flowing treatment process of the sewage and the system distributes water smoothly, and realizing long-acting safety operation; the filler which can form biomembrane is filled in the middle of the double-layer water distribution pipe, the sewage forms a reactor with independent biomembrane through the filler; by changing filler proportioning, the reactor is provide with a purification unit with micro-electrolysis function; the sewage enters to a primary purification process through the water distribution pipe network, thereby capable of removing 30% of pollutant.
Description
One, technical field
This patent is the water distributor of bilayer zone filler, and it is used for artificial swamp or land percolation system sewage treatment project, is the water technology that is applied to environment-friendly engineering.
Two, background technology
Since Economic development, the population growth, the town domestic sewage quantity discharged continues to increase, and water pollution problems is on the rise.For human and environment and Sustainable development harmonious economy, the improvement work of trade effluent and sanitary sewage is very important and urgent.The main method of disposing of sewage at present has physico-chemical process and biochemical process two big classes, and in the biochemical process based on traditional active sludge treatment process, but the construction investment of this technology is big, the energy consumption height, operational management requires high, for the small and medium-sized cities and the small towns of technology, fund strength weakness, use this kind technology, its construction and operation all are very difficult.And artificial swamp or land percolation treatment technology are to utilize physics, chemistry and biological triple coordinative roles in the natural ecosystems to realize purification to sewage, especially underflow type artificial ecological wetland treatment technology, to have initial cost few because of it, working cost is low, and management is simple, and treatment effect is good, and it is reliable and stable, strong and the treatment system energy self-perfection of capacity of resisting impact load, and have the advantages such as effect that greening environment improves ecology, in sewage disposal, applied.
In practice operation, also find some defectives, sewage treating efficiency is descended as operating short flow problem and system jams.
Three, summary of the invention
The art of this patent is the undercurrent water distribution pipe network system that is applied in underflow type artificial ecological wetland or the land percolation sewage disposal, and it has solved blocking problem in short stream of water distribution and the pipe.It is nested by inside and outside two layers of plastic pipe and forms, fill special filler between interior pipe and the outer tube, thereby constitute an independent biofilm reactor, effluent stream is crossed water distributor and is formed own ecological treatment system, have the effect of purifying waste water, can remove in the sewage 30% pollutent.
At water exhaust system emptying is set, utilize level pressure regularly system's filler to be washed, ensure the operation of the long-term efficient stable of wetland, emptied of water enters mud trap, supernatant liquor goes back to former pond and treats to handle again, transition cloth tank is set between first pond and second pond, available head aeration aerating or with the oxygenation of micropore gas distribution pipe, filling elastic filler in the groove forms the aerobe reaction, fills up the long deficiency of artificial swamp anaerobism, improve wetland hydraulic load 20～30%, the engineering land area can be reduced under the same condition of water quality,, the management road can be made at screened well loam cake cement plate.
Four, concrete enforcement
The art of this patent is that two plastics tubings will varying in size are nested and are combined into the layer cloth hydrophone, as shown in Figure 1, bassoon ∮ 110m/m (2) tubule ∮ 75m/m (1) wherein, punch by certain distance in corresponding position, the end band bell and spigot of tubule ∮ 75, its internal diameter is that ∮ 75 joins, water distributor can be combined to and need length. interior pipe (1) and outer tube (2) two ends weld fixing with annular endplate (4). in, fill between the outer tube and contain multiple metal oxide table and coarse granular filler, particle diameter is 15～20m/m, it is big to be easy to biological attachment biofilm and surface-area, biomass is many. and sewage flows to the packing area from interior pipe, through the filler mixing, to ooze out from outer tube again. the length of water distributor can connect combination as required. shown in figure (2), the water distribution pipe network is responsible for apportion multichannel water distributor by a center, shape such as dendritic, as shown in Figure 3. pipe network system is as shown in Figure 4 in artificial living wetland enforcement engineering. and lay rubble filler (3) upper strata in the bottom employing antiseepage processing of artificial swamp and spread coarse grain chiltern filler (4), water distribution pipe network (2) is located at bottom, touch the outer tube water distributing pore through filler and evenly ooze out and enter packing filter when sewage distributes by interior pipe, rise to the tracery wall gully-hole and enter transition tank (5), micropore gas-filled valve (9) is housed in tank, and shooting property filler (10), make it become an aerobic treating pond of contact, improved the long deficiency of artificial swamp anaerobism, improve the system purification processing power, can improve hydraulic load 20～30%, sewage enters the secondary wetland again from the bottom through transition water distribution groove (5) water distribution pipe network (7) enters header (6) collection discharge through filtering layer.
Establish emptying pipe network (7) at the wetland bottom, utilize water layer gravity, wash away dirt in the filtering layer when emptying, row enters catch basin (11), and clear liquid goes back to former pond and treats to handle again, and the cover plate that lays cement in the pump well upper end can be made the management road of wetland.
