Description

A kind of have activated charcoal filter of positive sewage backwash and preparation method thereof

Technical field

The present invention relates to water correction plant, particularly for the manufacture field of the strainer of the tap water of natural village, rural area and centralized residence community.

Background technology

The pollution of water resources is the most serious on the impact in rural area, substantially be that peasant household with good conditionsi and enterprises and institutions' digging well to get water are drunk, unqualified is just directly fetched water in river and in gully with simple and easy water pipe and is drunk, and the river in the current whole nation more than 92% and underground water are polluted, even severe contamination, its pollution is loathsome especially, especially underground water iron, manganese, alkali, chlorine, suspended substance, colloid substances, toxic byproduct, agricultural chemicals, bacterium, silt, iron rust, solid impurity pollution hazard, even there is well to have water, also severe overweight, cannot drink, threaten the healthy of the mankind, the enterprises and institutions in rural area casual household and inhabitation rural area and peasant household's centralized residence community do not use the condition of similar city tap-water, can only directly using underground water or earth's surface natural stream networks as the source of tap water, its present situation is, drinking water pollution, severe overweight, small towns tap water part exceeds standard, and does not reach People's Republic of China's " drinking water sanitary standard ", and the present situation of above-mentioned pollution constitutes rural area casual household and the enterprises and institutions in inhabitation rural area and the great threat of centralized residence community, rural area personnel health.

Known water purifier product design structure is comparatively simple, with low content of technology, especially to the filtration of underground surface water and the blowdown of positive back flushing, and all there is certain limitation in filtering accuracy and aquifer yield, above defect has become a technical bottleneck of this series products, and manufacturers really cannot make up this type of defect at present, its product is mainly based on the purification at exceed standard to town and country well water and surface water water source, the object reaching general tap water designs, can not solve natural village, rural area and rural area centralized residence population directly adopts the water source such as underground water or surface water to reach People's Republic of China's " drinking water sanitary standard " after purification, become the object of Drinking Water.As Chinese patent literature discloses " a kind of group removing of iron and manganese and soda acid water-purifying machine " (ZL200820062297.4), with underground surface water for water source, quartz sand filtration and filtration with manganese sand is adopted to be treated as Drinking Water.

Summary of the invention

The present invention is mainly in conjunction with China's reality, to push forward the building of a new socialist countryside further and country matches to geology disaster region Population safety water works, object is to provide a kind ofly has activated charcoal filter of positive sewage backwash and preparation method thereof, to solve rural groundwater and surface water reaches People's Republic of China's " drinking water sanitary standard ", become the problem of Drinking Water.Object of the present invention is realized by following technical scheme, a kind of have activated charcoal filter of positive sewage backwash and preparation method thereof, comprise PP cellucotton filtering layer, activated carbon filter layer, spun yarn strainer, it is characterized in that: the top of this encloses container is provided with water-in, sewage backwash mouth, container right flank below sieve plate has water outlet, the bottom of encloses container has just rinses sewage draining exit, this encloses container cylindrical shell and upper cover junction are provided with screw bolt and nut, an annular sieve plate is provided with in encloses container, sieve plate spreads all over water seepage hole, floor lever of sieve tray is provided with spun yarn strainer from bottom to top, it is also disposed with activated carbon filter layer, PP cellucotton filtering layer, in this encloses container, the top of PP cellucotton filtering layer is provided with arc water distribution cover, it spreads all over water hole, play distribution and the filtrate buffer action of water, the bottom of this encloses container cylindrical shell is also provided with a firm banking, be provided with screw rod and just rinsing blow-off pipe outlet, the water outlet of described filtration unit is communicated with the water-in of overhead water storage tower.

In above-mentioned design, the present invention adopts one-level multi-layer filtrating equipment and microcomputer program Controlling System device, with the needs for natural village and rural area centralized residence community drinking water treatment.As concerning the water source such as rural groundwater, surface water, the present invention carries out the filtration of PP cellucotton, activated carbon filtration and the process of spun yarn metre filter to it.

Compared with prior art (on the basis of existing quartz sand filtration and filtration with manganese sand process), the present invention is directed to water source, rural area, add the treatment steps such as the filtration of PP cellucotton, activated carbon filtration, spun yarn metre filter.In the present invention, PP cellucotton effectively can tackle macrobead silt, iron rust, impurity, suspended substance, the removing incrustation scale removed in underground water, surface water water; Gac can effectively threaten the granulometric impurity in maximum chlorine residue, peculiar smell, heterochromatic, foreign odor thing, agricultural chemicals, trichloromethane and water to HUMAN HEALTH, stop the objectionable impuritiess such as bacterium, chemical substance and heavy metal element in absorption water, remove the organism in water, retain the useful mineral substance of human body and trace element; Spun yarn strainer effectively again can be tackled silt, iron rust, impurity, suspended substance, the various mechanical impurity removed in water, thoroughly remove incrustation scale, several mineral materials and the trace element such as potassium, sodium, calcium, strontium, carbonic acid, metaphosphoric acid useful to human body is provided simultaneously, thus makes water quality mouthfeel more sweet pure sweet.

The present invention has following features: 1, effectively can tackle macrobead silt, iron rust, impurity, suspended substance, the removing incrustation scale removed in underground water, surface water water.2, can effectively threaten the granulometric impurity in maximum chlorine residue, peculiar smell, heterochromatic, foreign odor thing, agricultural chemicals, trichloromethane and water to HUMAN HEALTH, stop the objectionable impuritiess such as bacterium, chemical substance and heavy metal element in absorption water, remove the organism in water, retain the useful mineral substance of human body and trace element.3, effectively again can tackle silt, iron rust, impurity, suspended substance, the various mechanical impurity removed in water, thoroughly remove incrustation scale, several mineral materials and the trace element such as potassium, sodium, calcium, strontium, carbonic acid, metaphosphoric acid useful to human body is provided simultaneously, thus makes water quality mouthfeel more sweet pure sweet.4, the objectionable impurities be suspended in filter cylinder water body can effectively be discharged, discharge efficiency is up to more than 99.8%, also effectively can discharge the various objectionable impuritiess of absorption in cartridge surface, positive back flushing ER for emission rate is up to more than 99%, keep the circulation of filter core internal watercourses, effectively prevent out aqueous metamorphism, monolithic computer chip controls, have automatic detection function, automatic-discharging number of times and drain time can be arranged arbitrarily.5, by supporting the use with rear class filtration unit, effluent quality is better than People's Republic of China's " drinking water sanitary standard ".

The present invention is economic and practical, and water purification automatic water-supply ability 8-38 ton per hour, can solve the Drinking Water of 26800 populations, is particularly suitable for natural village and centralized residence community, rural area and uses.
