Description
Technical field
The utility model belongs to the sewage disposal technology category, especially relates to a kind of drop water aeration-quick diafiltration combined system.
Background technology
At present; The research that artificial rapid infiltration system is handled domestic sewage in rural areas by using receives the big concern of People more and more; Artificial rapid infiltration system (CRI) is meant controlledly the surface that sewage is invested in the filtration media that manual work constructs; Make its different physics, chemistry and biological action of experience in the process of infiltration downwards, finally reach the process of purifying waste water.It is on the basis of the quick percolation treatment of traditional sewage system (RI), to grow up, its core be adopt penetrating quality preferably natural river sand, haydite and coal gangue etc. replace natural soil layer for main filtration media, thereby improved hydraulic load greatly.Yet; The mechanism of CRI system is unclear fully as yet so far; Particularly for the several main parameters in the system design, like system's reoxygenation problem, hydraulic load, aspects such as process combination problem, filtration media, operation scheme also have many problems to need further research.Its reoxygenation situation has tremendous influence to the treatment effect of system, and the result of reoxygenation condition difference causes the organic aerobic biodegradation effect of internal system undesirable often, and nitrification is restricted, the major cause of system handles weak effect.So for the traditional wastewater treatment system, the solution of CR I reoxygenation problem seems even more important.In order to improve reoxygenation efficient, the method for reoxygenation employing at present mainly contains three kinds: the one, adopt the periodically mode of operation strengthening system reoxygenation of alternation of wetting and drying; The 2nd, utilize the root system of plant that internal system is carried out reoxygenation; The 3rd, vent-pipe is installed internal system is carried out reoxygenation.Traditional reoxygenation method is not that efficient is too low, is exactly that energy consumption is too high, all can not reach satisfied effect.Therefore, it is high to develop a kind of reoxygenation efficient, and energy consumption is low, and moving simple novel C RI all has very important meaning for utilization and the development of CRI.
Simultaneously; Mountain region and knob account for 65% of China's area; Samll cities and towns' great majority are located in mountain area and knob, belong to the economically less developed region, receive the restriction of the level of economic development; They often are difficult to bear the high construction cost and the high working cost of sewage work, thus sewage disposal technology of selecting and technology should have capital cost low, be easy to built by separate periods and the lower technology of working cost; And mountain region and knob topographical elevation difference are big, and the topographical elevation difference of same samll cities and towns can reach tens meters even rice up to a hundred sometimes, if can utilize this part potential energy fully, can significantly reduce the working cost of sewage work undoubtedly.
So the potential energy that utilizes topographical elevation difference to form carries out watercourse aeration, utilizes CRI art breading sewage again, is a kind of less energy-consumption, high-level efficiency is with strong points, the combination process that exploitativeness is high.
The utility model content
The purpose of the utility model is exactly the problem that the reoxygenation of a kind of CRI of solution is provided for the defective that overcomes above-mentioned prior art existence, improves the drop water aeration-quick diafiltration combined system of the last effect of CRI.
The purpose of the utility model can realize through following technical scheme:
The diafiltration combined system of a kind of drop water aeration-is fast set up the combination process of drop water aeration and CRI on the big landform of drop, combined system comprises drop water aeration irrigation canals and ditches and rapid infiltration pool; The stepped from top to bottom setting of described drop water aeration irrigation canals and ditches utilizes the physical features discrepancy in elevation, builds nature and falls irrigation canals and ditches; Can build into stepped appearance, increase contact area, help reoxygenation to raise the efficiency; Described rapid infiltration pool is located at the bottom of drop water aeration irrigation canals and ditches; The bottom of drop water aeration irrigation canals and ditches is provided with water distributor, and this water distributor connects drop water aeration irrigation canals and ditches and rapid infiltration pool, and the bottom of rapid infiltration pool is provided with water shoot.
Be equipped with rubble at the bottom of the canal of described drop water aeration irrigation canals and ditches, and plant and to be implanted with heavy water perennial plant, play adjusting water quality; Remove most of sedimentable matter, prevent to stop up the effect of diffusion cell, via the treating water that falls of drop irrigation canals and ditches; Get into the irrigation canals and ditches bottom, in the rapid infiltration pool of batching again.
Described rapid infiltration pool is pedosphere, coarse sands layer, pebble bed, slag layer and metalling from top to bottom, and the slag layer can be strengthened the adsorption effect to phosphorus.Sewage gets into metalling behind the slag layer, and this layer oxygen level is lower, mainly carries out denitrification; And have the function of collecting water concurrently, and pebble bed is water distribution layer, and water distribution layer is above to be coarse sands layer and pedosphere; Two-layer migration that sewage soaks into through soil and the rising power of root system of plant makes progress; The soil surface kind is implanted with artificial pasture, has increased the regulation effect in diafiltration district, has also beautified engineering-environment simultaneously.
Described water distributor is wrapped with the water-permeable geotextile, with water distribution uniformity and prevent that the grains of sand from stopping up.
The water side of described water distributor is located in the pebble bed of rapid infiltration pool.
The feed-water end of described water shoot is located in the metalling of rapid infiltration pool.
Compared with prior art, the utility model makes full use of characteristics such as the physiographic relief discrepancy in elevation, be applicable to possess this topographical condition, population is less than 10,000 people's samll cities and towns; Has capital construction and working cost is low; Operational management is simple, is the less energy-consumption WWT combined system that is applicable to hilly small towns, utilizes the nature drop through the drop reoxygenation; Need not to promote and power consumption; Whole artificial rapid infiltration system major part all is positioned at underground, has strengthened the security and the disguise of facility, has also avoided the generation of FAQs in the WWTs such as stench, mosquito grow.
