Description
Technical field
The utility model relates to the filtration treatment of water, refers in particular to the anti-granularity rapid filter of upward flow to the processing of cities and towns running water, town sewage processing, industrial water supply and wastewater treatment, industrial circulating cooling water processing, middle water Treatment for Reuse, swimming pool circulating water treatment, underground water deferrization and demanganization processing, low-temperature and low turbidity water treatment.
Background technology
In modern water-purifying process,, filter fast and remain very important together indispensable cleaning procedure no matter which kind of new type purification equipment occurs.Recent decades are because polytype rapid filter has appearred in the continuous development of filtering technique.These filter tanks are endowed different titles with the characteristics in its structure or the operating process: conventional rapid filter, siphon filter, gravity valveless filter tank, pressure filter, single-valve filter, double-valve filter pool, air valve filter tank are arranged, move flushing cover filter tank, double-bed filter, V-type filter tank or the like.Although there is very big difference in these filter tanks on control principle, the water (flow) direction when filtering is from top to bottom, filters from fine to coarse along the filter material layer grain diameter.Therefore, we are defined as down it to the positive granularity of stream filter tank.
The following of employing at present to its technical process of the positive granularity of stream filter tank is: treat that drainage contacts the fine filtering material on filter material layer surface from top to bottom earlier.A large amount of suspensions are retained down in the 10～15cm degree of depth of top layer, and then the coarse media of bed of material bottom flows out outside the pond after filtration.In filtration, the fine filtering material particle diameter on surface is little, and the filtering layer pore diameter of being made up of them is also little, treats that the suspension that particle diameter is bigger in the drainage at first held back by top layer fine filtering material.Because surface detail filtrate pore diameter is little, is stopped up by suspension soon.The filtering layer loss of flood peak increases very fast, though the lower coarse filtrate has bigger porosity, can only hold back small amount of impurities, and a large amount of fine impurities are difficult to be trapped.Before the retaining power of not bringing into play it, just needed backwash, therefore, the retaining power of lower coarse filtrate is fully utilized far away.It is satisfactory that this situation is difficult to, but filter material layer after backwash because the hydraulic classiciation effect of different-grain diameter particle always is formed naturally up-thin-low-thick level, can't change.Such filter material layer structure is irrational.In the positive granularity of stream is filtered, account for 85～90% not performance section dirty effect of thick or thicker filtrate following in the filter material layer.The shortcoming in this filter tank be filter cycle short, filtering velocity is low, the loss of flood peak is big.
Past also once used the method that as far as possible makes the particle diameter of filter medium homogenization to solve this problem, but the particle diameter of large quantities of filtrates reaches homogeneous completely, and this all has been subjected to certain restriction technically and economically.
Along with the needs of social development and construction and to drinking water quality and sanitarian an urgent demand, we answer the filtering technique of exploratory development economical and efficient to obtain better filter effect.
That adopts at present is following to the positive granularity filter type of stream, because of the filter material layer structure that causes particle diameter of filter medium to increase gradually from top to bottom after the backwash is irrational.Give full play to the dirty effect of cutting of whole filter material layer again in order to improve water quality, the bed of material should after filtration to treat drainage
This is the thin filter type in thick earlier back, and promptly the anti-granularity of upward flow is filtered.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of technology advanced person, modern design, scientific and reasonable for structure, simple and reliable are provided; Filter cycle is long, filtering velocity is high, the loss of flood peak is little, unit volume aquifer yield height, effluent quality is good, energy-saving effect is remarkable, volume is little, the anti-granularity rapid filter of the upward flow of reduced investment.
The technical solution of the utility model is: treat that the drainage water inlet pipe is connected with distributing water room, set gradually the modified form water distribution system above the distributing water room, lay bed course, filter material layer, space above the filtrate is provided with the backwash rhone, space up is provided with water leg again, one end of water leg is provided with the clear water canal, and water leg is communicated with the clear water canal, below the clear water canal drainage ditch is set, backwash rhone and drainage ditch are communicated with, and the backwash water inlet pipe is connected with distributing water room.
The utility model has the advantages that: filter material layer is thicker, so suspension not only is trapped in the coarse filtration bed of material of bottom, and is held back by whole filter material layer, and therefore, the filter material layer resistance is little, and the suspension of holding back is many.
In order to overcome the filter material layer expansion that causes because of the filtering velocity height and to be flow regime, select suitable filtrate material, optimize the particle diameter of filter medium grating, the thickness of adjusting filter material layer and bed course is very important.
The following of the utility model and equal scale compared to the positive granularity of stream filter tank, and aquifer yield can improve about 40%, and investment can be saved about 30～40%, and volume is also corresponding to be dwindled.Its economic benefit and social benefit are obvious.
The utility model can be used for the construction in new filter tank, and also applicable to being tapped the potential and upgrade technologically in the old filter tank of tradition, its market prospects are wide.
