2=350mm, the part that solid circular shafts 1.1 exposes is not coated by wire netting.
In the present embodiment, circular filter drum 1 and gusset 1.2 all weld with the steel of stainless steel or antirust processing.At least two circular filter drum 1 can be connected in parallel, parallel being arranged in river course, irrigation canals and ditches, sewage treatment facility.
A kind of hydro powered type biological filter provided by the invention dam water cleaning systems installation steps: first on riverbank by circular filter drum 1 welding fabrication, by side direction graticule mesh and a piece of middle lattice graticule mesh install, then by each " V " font cavity of circular filter drum 1 straight up, press bamboo-carbon layer 1.4.1, Wingdale layer 1.4.2, the filling filtrate gratings such as haydite layer 1.4.3 and distribution sequence are successively filled, compacting and sealing with wire netting grid, after sealing is filled in each " V " font angle region 2, circular filter drum 1 is rotated, the state that the next one " V " font angle region 2 is kept straight up, adopting uses the same method fills filtrate, then with the sealing of wire netting grid, until all cavity has been filled, then adopt the pattern of integral hoisting circular drum 1 to be fixedly mounted on to reinforced concrete plinth first support pier of building, on the second support pier.
The principle of work of a kind of hydro powered type biological filter provided by the invention dam water cleaning systems: the microbial film of granulated filler and apposition growth thereof of take is main treatment media, give full play to the physisorption of biological metabolism, physiology filtration, microbial film and filler, sewage is carried out a biological disposal upon, pollutent is wherein removed.Microorganic adhesion is on filling surface, and sewage is in the carrier surface process of flowing through, and by the absorption of organic nutrient substance, oxygen, to the biological oxidation occurring in the diffusion of microbial film inside and film, decomposes pollutent.In biological filter dam, pollutent, dissolved oxygen and various essential nutritive substance first will be through Liquid Phase Diffusion to biofilm surfaces, then progressing into microbial film inside, both for being attached to biological group on the film on raw material, provided growing nutrient, in the process of diffusion, by biological membrane biological, decomposed simultaneously and transform, finally forming various meta-bolites (CO
2, water etc.).In addition, the filler on biological filter dam itself just has crown_interception and the adsorption of good machinery.Effluent stream is when filler, and filler is compaction state, utilizes feature and biomembranous biological flocculation that particle diameter of filter medium is less, the suspended substance in trap water, and the microbial film that assurance comes off can not blown out with water.Meanwhile, the producible viscous substance under metabolism of the microorganism on filler can be brought into play adsorption bridging effect as carbohydrate, ester class etc., with suspended particle and colloidal particle, is bonded together, and forms tiny flco, by contact flocculation effect, is removed.Because aerating biological filter pool filler microbial film specific surface area is larger, guaranteed that filter tank is holding a large amount of microorganisms, this for the organic pollutant in further degradation of sewage, obtain good treatment effect, good assurance is provided.
A kind of hydro powered type biological filter provided by the invention dam water cleaning systems, easy maintenance, with low cost, the later stage can be opened rear replacing filtrate one by one by " V " font angle region 2, again recover to use, and maintenance update easy handling.The matrix such as bamboo-carbon layer 1.4.1 or charcoal layer, Wingdale layer 1.4.2, haydite layer 1.4.3 are loaded in grating and filling thickness ratio, pack in circular filter drum 1, adopt part to be placed in attached biological film, part under water and be exposed to air reoxygenation recovery more naturally, save the requirement to aeration, then taked interval some cycles rotation interchangeable to ensure the method for disposing of sewage continuously.It is short that the method has overcome the biological filter cycle of operation, the deficiencies such as recoil is frequent, the rear system destruction of recoil, use the method for intermittent type recovery filtrate activity instead, and the decoration form of employing interception dam formula, physical filtering and biomembrane purification method are combined, make it be more suitable for the improvement in micropollutant water and river.
