Description
Technical field
The present invention relates to a kind of filtration-fabric anti-clogging strengthening compound flow constructed wetland domestic sewage processing system.
Background technology
The wastewater treatment rate in the present cities and towns of China is very low, most of life and the not treated river course that directly enters of factory effluent, cause the water body severe contamination, simultaneously along with China's cities and towns water consumption and water displacement constantly increase, urban sewage treatment technology based on aerobic activated sludge process, though show as the pollutants removal rate height, shortcomings such as infrastructure investment and working cost height cause many sewage works to be difficult to raise funds to build or be difficult to keep on the go because of cost is high.Treatment effect is good, the ammonia nitrogen removal ability strong because the few constructed wetland waste water treatment technology of good processed water quality, sludge yield has for the artificial swamp technology, during-operation service convenient management, engineering capital construction and running expense is low and for principal features such as the load variations adaptive faculty are strong, can improve the ecological environment simultaneously and becomes the water technology of domestic and international common concern.
In the artificial wetland treatment process evolution, compound flow constructed wetland is one of field with fastest developing speed.Problems such as research of artificial swamp at present and application mainly concentrate on the improvement of eutrophication water, and the processing that is applied to sanitary sewage then exists obstruction, oxygen supply deficiency, hydraulic load is little, floor space is big have limited its widespread use.The correlation technique of strengthened artificial wet land how: anti-clogging plug, guaranteeing oxygen supply, improve hydraulic load satisfying under the prerequisite of treatment effect, is the challenge problem of pendulum in face of ours.
The formation of colmatation zone is that the chemical precipitation reaction that takes place in deposition, filler space biological growth and the decomposition and the filler in filler internal particle gap of organic solid thing etc. produces in the wetland, and is relevant with the batch factors such as activity of situation and microorganism of packing material size, organic loading, water inlet concentration of suspension, sewage.According to more than 100 investigation that make up wetlands of the U.S., the wetland that half is nearly arranged has formed obstruction in after putting into operation 5 years.After making up the wetland obstruction, the wet land system permeability coefficient obviously reduces, and has changed its hydraulic characteristic and mass transfer process, thereby influences system's operation.Make up wetland for composite vertical current, obstruction also can form stromal surface and seriously catchment, and blocking oxygen is to the hypothallus internal diffusion, thus the clearance of reduction organic matter and nitrogen material.
Artificial wet land system holds back or the characteristic of the usefulness of degradation of organic substances and nutritive salt and filler and particle diameter distribution, oxygen delivery capacity and oxygen distribution, flow-shape, blowdown mode etc. are relevant.At first, not only to make the filling filler have enough specific surface areas to satisfy the needs of microorganic adhesion and water treatment in the high-efficiency artificial wetland technology, also should make sewage flow through system swimmingly and blockage problem not occur.But simple select for use small particle size filler to increase to be prone to blockage problem when specific surface area is improved the treatment effect situation.In order to solve blockage problem, several anti-clogging plug wet land systems and pre-anti-clogging plug measure have been developed both at home and abroad in succession: 1. intermittent operational mode.The double-current attitude anti-clogging plug artificial wet land system that for example a kind of vertical flow combines with oblique stream, this system principal feature is by regular emptying pond body, mud in the pond is taken out of with current, thereby play anticlogging effect, but regularly the drainage works amount is big, and the mixed soil water yield of discharging is also bigger, and this has just increased the secondary treatment problem to wetland.The recovery measure that can take for the packing layer that seriously stops up has and stops bed and stop work or means such as crop rotation, replacing top layer sand; 2. soil animal is repaired.Utilize soil animal to repair and stop up the scheme that solves blockage problem that artificial swamp also is the comparison novelty, promptly in wetland, throw in the soil animal earthworm, play the effect of cleaning and mediation matrix simultaneously by the loosening matrix of the orthobiosis behavior of earthworm, this method expense is cheap, construction maintenance is simple, but the growth of earthworm has certain requirement to environment, such as temperature, the growth and breeding situation difference of earthworm under the condition of different temperatures, water ratio is also influential to it in addition, the too high activity to earthworm of water content is very unfavorable in the soil, system's running maintenance difficulty; 3. sewage quality preconditioning technique.For example by pre-treatment facilities such as grid, settling bath are set before wetland, reduce the particulate matter that enters wetland, avoid the local process of stopping up or slowing down the wetland obstruction of artificial swamp, but the just large particulate matter that is retained down like this, remaining solvability and colloidality organism still can enter and cause non-physical property obstruction in the artificial swamp; 4. optimize the use of packing material size distribution or new packing.Satisfying under the processing requirements prerequisite of wetland, adopting filler or employing multilayer filtrate,, increasing containing of whole packing layer of dirty ability with this penetration depth that improves filler than the coarse grain footpath.Simultaneously, also can improve the water distribution situation, avoid local and stop up; 5. fall reoxygenation or artificial aeration.Because organism in the water inlet and ammonia-nitrogen content add the demand of microbial activities to oxygen greater than the oxygen-supplying amount of system, have caused system's oxygen imbalance between supply and demand.By increasing system dissolves oxygen amount, promote biological activity, oxidative degradation organism and ammonia nitrogen material can improve processing efficiency, also can alleviate blockage problem.
Though more than the technology of pre-anti-clogging plug obtain certain effect in practice, make up wet land system and stop up and be still a universal phenomenon, blockage problem is not also had good countermeasure both at home and abroad at present.Make up process and influence factor more complicated thereof that wetland stops up, depend merely on certain technology and be difficult to solve blockage problem, in the design of wetland and in servicely should consider comprehensively, systematically that various factors and process are with pre-anti-clogging plug.
