Abstract

The utility model discloses a miniature water purifier, belonging to the technical field of water treatment using low sand filtration. Good filtering effect can be obtained, approaching or reaching drinking water standard when the thickness of sand layer is larger than 600mm, and the temperature is over 10 DEG C by utilizing the effect of steady viscous biological filter membrane formed by the sand layer filtered in the speed lower than 0.3 m/h, but no miniature equipment is suitable for filtering the water in rainfall collecting cellar till now. The miniature slow filtering water purifier adopts closure holes in the assemblies of the turbidity water store storehouse, the sand layer water filtering storehouse and the purifying water outlet. The technique of the closure tubule and the bearing filter modules meets the requirements of miniaturization, requiring no applied power, and working by the gravity of the water. The utility model has the advantages of low manufacturing and operation cost.

Description

Slowly filter water purifier

Technical field

The utility model relates to water treatment field, especially the slow filtration water technology.

Technical background

Generally set up Ji Yushuijiao in the water-deficient area, rural area, water quality reaches standard for drinking in the cellar for storing things because water cellar environment and water cellar structural reason can't make, must be with its further purification.The method of water purifying treatment is a lot of at present, but many genus equipment bulky structure complexity, consumes energy is many, is not suitable for farmers''s water purification application on a small scale.Slowly filter water purification treatment technology and relatively meet farmers''s requirement of purifying drinking water on a small scale, slow drainage treatment process is that the water that needs purify is passed through the water purifier layer of sand with slower flow velocity, obtains purification effects.In whole scavenging process, have effects such as mechanical filter, biological degradation, biological absorption and chemical disinfection.Layer of sand in the cleaner has the effect of mechanical filter, simultaneously in the very slow natural water of flow velocity, when flow velocity≤0.3 meter/hour, can form the biological filter membrane with viscosity between filtrate, and the gap of filtrate is reduced, all suspended substances in almost can trap water; The adsorbed organism of this biological filter membrane provides good condition for microbial growth breeding in the water.So growth and breeding a large amount of various types of microbial populations in filter membrane,---bacterium---the protozoic food chain that formed organism simultaneously.Under the effect of heterotroph and autotrophic organism, carbonaceous organic material is oxidized to water and carbonic acid gas, and itrogenous organic substance is oxidized to ammonia, and then is converted into nitrite under the effect of Nitrosomas, further is converted into nitrate again.Like this, the organism in the water is almost removed fully, and bacterium is as link in the food chain and prey, or held back by lower floor's filtrate and dead, practice shows, as long as temperature is more than 10 ℃, thickness of filter bed is not less than 600mm, and nearly all bacterium and virus all can be removed.

Be not difficult to find out that slow drainage treatment process has following characteristics: do not need any mechanical power, only depend on the water own wt and control filtering velocity in the time of≤0.3 meter/hour, just can reach the requirement of water treatment; Stable and reliable operation, management is simple; Water producing cost is low; Effluent quality near or reach the standard of drinking water quality.But this technology only is used for large-scale engineering of water treatment at present, is applicable to that the small-sized slow drainage treatment technology and the equipment of farmers' is not also seen.

Summary of the invention

The purpose of this utility model provides a kind of small-sized water purifier of filtering slowly that is used for drink water purifying that farmers' uses that is suitable for.

The invention main points are as follows:

A kind of water purifier of filtering slowly has muddy water storage warehouse, layer of sand drainage storehouse, pure water inlet assembly, water purifier base.The top in layer of sand drainage storehouse is inserted in the bottom of muddy water storage warehouse, and the bottom in layer of sand drainage storehouse is connected with the pure water inlet assembly, and insert in the water purifier base in layer of sand drainage storehouse.In muddy water storage warehouse and layer of sand drainage storehouse not jljl mutually boundary respectively be provided with and be no less than a support filter assemblies.Be provided with the aperture member that dams in muddy water storage warehouse bottom, bottom, layer of sand drainage storehouse is connected by the tubule that dams with the pure water inlet assembly.

The aperture member that dams is to have the aperture that dams in the bottom of muddy water storage warehouse, the diameter of aperture is 0.1-3mm, dam and wear a fine rule that can move freely in the aperture, the upper end of fine rule connects the bead that buoyancy is bigger, and the lower end of fine rule connects the bead that buoyancy is less.

The support filter assemblies has a screen holder with holes, covers filtering net on screen holder with holes, and netted support bracket is housed on filtering net, and netted support bracket edge card is clipped in filtering net wherein in screen holder with holes simultaneously.

A kind of form of pure water inlet assembly connects crooked rising pipe and the outlet valve that makes progress for the exit end at the described tubule that dams, and the diameter of the tubule that dams is 0.1-3mm.

The another kind of form of pure water inlet assembly is for having a clear water storehouse, exit end at the described tubule that dams is connected with prosopyle, bottom, clear water storehouse, clear water Cang Gai is equipped with in the upper end in clear water storehouse, and outlet valve is equipped with at middle part, clear water storehouse, and the support filter assemblies is equipped with in the bottom in clear water storehouse.

The utility model is simple in structure, does not need additionaling power, carries out work by the gravity of water own, and by the hole and the tubule control filtering velocity of damming of damming, manufacturing cost and use cost are all very low, and purifying water effect is good, is specially adapted to the Jiao Shui that catchments of farmers' and purifies and be the tap water use.
