According to the deferrization and demanganization water purifier that the utility model proposes, compared with prior art, have collection aeration, filtration, the multiple function of precipitation is an one, and the advantage that can rely on waterpower to wash automatically, any medicament need be do not added in the operational process, significant deferrization and demanganization effect can be reached.When removing iron, manganese, can also remove the ammonia nitrogen and the nitrite nitrogen of some amount, water quality after treatment meets the Drinking Water water quality standard of national regulation, and the content of iron is no more than 0.3 mg/litre, and the content of manganese is no more than 0.1 mg/litre.Said device features rational structure, volume is little, and result of use is stable, and the efficient height is reduced investment outlay, and convenient management, but continuous water supply are applicable to industries such as papermaking, weaving, printing and dyeing, food, drinks, beverage, can.

Fig. 1 is the structural principle synoptic diagram of one of the utility model embodiment;

Fig. 2 is the lateral plan of Fig. 1.

According to accompanying drawing embodiment of the present utility model is described in detail below:

As shown in the figure, the deferrization and demanganization water purifier mainly is made up of water inlet system, filter tank, siphonic system three major parts.This routine water purifier has two identical cover filter tank and siphonic systems.

Water inlet system includes set secondary supplement aerating apparatus 9 in water inlet pipe 2 and the efflux aerator that is connected with water inlet pipe, water inlet distribution reservoir 6 and the distribution reservoir, U-shaped pipe 15.The water inlet distribution reservoir 6 at water inlet pipe 2 (not drawing among the figure) access arrangement top behind the one-level efflux aerator of device external, its pipe head that enters distribution reservoir partly is secondary supplement aerating apparatus 9, the both sides of aerating apparatus 9 are provided with baffle plate, distribution reservoir is divided into two water tanks (as Fig. 2), is communicated with U-shaped pipe 15 respectively in the bottom of two water tanks.

The filter tank is partly by filter tank 4, radial-flow water-distributing device 3, manganese layer of sand 5, pebble bed 18, filter screen, orifice plate 17, catchment area 16 formations such as grade.Two U-shaped pipes that water inlet distribution reservoir 6 extracts are connected with two filter tanks 4 respectively, and the water outlet of U-shaped pipe in the filter tank is provided with baffle plate, constitute radial-flow water-distributing device 3, be provided with artificial manganese layer of sand 5, pebble bed 18 and filter screen in the filter tank, orifice plate 17 is established in filter tank bottom, is catchment area 16 below the orifice plate.

Siphonic system is by siphon pipe 8, and siphon extraction pipe 7 destroys bucket 13, auxiliary siphon tube 14, and overflow pipe 20, drain well 22 grades are partly formed.Siphon pipe passes filtered water tank 1 and is drawn out to the casing top from top, filter tank, extend downward drain well 22 through one section bend pipe along the casing outside again.Destroying bucket 13 is located in the filtered water tank of 4 tops, filter tank, destroying bucket one end partly is communicated with siphonal bend pipe, partly draw auxiliary siphon tube 14 and extraction pipe 7 from siphonal bend pipe, the other end of extraction pipe is connected with auxiliary tube, the decline pipeline section of auxiliary tube and siphon pipe 8 is introduced drain well side by side, and the drain well below is provided with main drain 10.Water inlet overflow pipe 20 is located at into water distribution reservoir top, and the top of filtered water tank also is provided with rising pipe 11 and clear water overflow pipe 21, and the casing outside is provided with cat ladder 19 and manhole 12.

Equipment running process is as follows:

Former water is behind one-level ejector aerated reaction, and by the water inlet distribution reservoir of water inlet pipe access arrangement, set secondary supplement aerating apparatus in distribution reservoir enters in the water airborne oxygen again, repeatedly iron, manganese is carried out preliminary redox.Water is evenly divided to both sides by the baffle plate in the distribution reservoir again, send into the filter tank by the U-shaped pipe that links to each other with distribution reservoir, by the mouth of pipe radial-flow water-distributing device that baffle plate constitutes is set, making into, water passes through filtering layer equably, and keep certain filtering velocity, in the catchment area precipitation, clear water rises in water tank gradually, at last by the rising pipe water outlet.
