Description
Technical field
The present invention relates to the device that a kind of forcibly changing water channel removes removing ferro in water and mn ion, belong to water-treatment technology field, for removing the Fe and Mn of underground water.
Background technology
Along with the quickening of expanding economy and urbanization process, the problem of water scarcity has caused people's attention, and water resources shortage has become one of bottleneck of restriction China Economic development.The regional population that China's content of iron and manganese exceedes drinking water standard reaches 3.31 hundred million, and its water yield accounts for underground water total storage more than 20%, and making full use of this part groundwater resource, to make it to become fine water imperative.There is technical backwardness in domestic and international existing underground water deferrization, demanganization process and equipment, fluctuation of service, and energy consumption is large, the problems such as content of iron and manganese still exceeds standard in water after processing, and iron content, manganese underground water majority are in economically underdeveloped area.Therefore seek a kind of technical feasible, reasonable in economy, deferrization and demanganization novel process and equipment that practicality is stronger are very necessary.
According to different condition of water quality, adopt biological deferrization demanganization treatment technology, by weak aeration, single filter technique, realize iron, manganese with layer removal, simplify greatly traditional technology.Further research is found, current, near strainer barrel, because popular route is short, resistance is little, very easily penetrate filtrate, cause short stream; And the filtrate of middle part fails to give full play to the effect of interception ferrimanganic in strainer.
Summary of the invention
The object of this invention is to provide the device that a kind of forcibly changing water channel removes removing ferro in water and mn ion, for above-mentioned reason, change the structure of filter tank inside, make current evenly be covered with whole filtrate, make full use of filtrate, improve the clearance of ferrimanganic, and do not affect the steady running of filter tank; It is by changing the structure of filter tank inside, forcibly changing water channel, make current evenly be covered with whole filtrate, make full use of filtrate, sluicing water distribution board has reduced streaming potential, reduce the direct impact of current to below filtrate, on tank skin, there is flow resistance plate, can make filter interior current water distribution even, the equilibrium of plane each point resistance, improve the clearance of iron, manganese, and do not affected the steady running of filter tank.
Technical scheme of the present invention is achieved in that a kind of forcibly changing water channel removes the device of removing ferro in water and mn ion, formed by water inlet pipe, water distribution board, filtrate bed, flow resistance plate, rising pipe, water distribution system, tank body, it is characterized in that: filter tank top connects with water inlet pipe, water distribution board is positioned at filter tank, water distribution board horizontal center is arranged in water inlet pipe lower end, filtrate berth is in the middle section position of filter tank inside, filter tank inwall has flow resistance plate, water distribution system is positioned at filter tank filtrate bed below, and filter tank bottom is connected with rising pipe.
Described water distribution board edge is provided with baffle plate upwards.
Described flow resistance plate circularizes structure or annular has even gap structure ring on filter tank inwall.
Described flow resistance plate is 1 ~ 3 layer.
The described device working process of removing removing ferro in water and mn ion is as follows: will be full of filtrate bed 3, static cultivation 16-24 hour for inoculation water; Then open backwash pump, flow velocity remains on 0.5-5L/s.m
2, make backwashing water enter filtrate bed 3 through water distribution system 6, the water that enters filtrate bed 3 flows from bottom to top, outside water inlet pipe 1 is got rid of filter tank 7; The whole work period maintains 10 minutes; Close back-purge system, then open water inlet pipe 1, in the water outlet of 10 minutes initial stages, contain backwashing water, directly discharge, does not supply with user.
Positively effect of the present invention is to increase barrel resistance, extends the popular route of current, avoids short stream to occur, and makes current evenly be covered with whole filtrate, makes full use of filtrate, improves the clearance of ferrimanganic, and does not affect the steady running of filter tank.

Fig. 2 is the structure iron of the first flow resistance plate of the present invention.
Fig. 3 is the structure iron of the second flow resistance plate of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further: as Fig. 1, shown in 2, a kind of forcibly changing water channel removes the device of removing ferro in water and mn ion, by water inlet pipe 1, water distribution board 2, filtrate bed 3, flow resistance plate 4, rising pipe 5, water distribution system 6, tank body 7 forms, it is characterized in that: filter tank 7 tops connect with water inlet pipe 1, water distribution board 2 is positioned at filter tank 7, water distribution board 2 horizontal centers are arranged in water inlet pipe 1 lower end, filtrate bed 3 is positioned at the middle section position of filter tank 7 inside, there is flow resistance plate 4 filter tank 7 inwall both sides, water distribution system 6 is positioned at filter tank 7 filtrate bed 3 belows, filter tank 7 bottoms are connected with rising pipe 5.
Described water distribution board 2 edges are provided with baffle plate 8 upwards.
Described flow resistance plate 4 circularizes structure or annular has even gap structure ring on filter tank 7 inwalls.
Described flow resistance plate 4 is laid 1 ~ 3 layer according to practical situation.
Go the working process of removing ferro in water and mn ion as follows: will be full of filtrate bed 3, static cultivation 16-24 hour for inoculation water; Then open backwash pump, flow velocity remains on 0.5-5L/s.m
2, make backwashing water enter filtrate bed 3 through water distribution system 6, the water that enters filtrate bed 3 flows from bottom to top, outside water inlet pipe 1 is got rid of filter tank 7; The whole work period maintains 10 minutes; Close back-purge system, then open water inlet pipe 1, in the water outlet of 10 minutes initial stages, contain backwashing water, directly discharge, does not supply with user.
When underground water is drawn out of ground, while entering filter tank 7 top by water inlet pipe 1, disperse through water distribution board 2 surfaces, increase thus aqueous vapor contact area, strengthening air water mass transfer usefulness, improves oxygen-transfer efficiency, and water distribution board 2 has reduced streaming potential, reduce the impact of current to below filtrate bed 3, completed drop water aeration one time; Gravity fall in the time that water covers the baffle plate on water distribution board 2 limits, enters the filter material surface of filtrate bed 3 upper ends, completes drop water aeration for the second time.
At filter tank 7 inwalls, 1-3 layer flow resistance plate 4 is set, in the time of water process filtrate bed 3, flow resistance plate semi-finals system changes water channel, and current are formed to resistance, has extended the residence time of current, takes full advantage of filtrate; Can effectively dredge current flows without dead angle simultaneously, make current be full of whole filtrate bed 3, when filtrate bed 3 moved after for some time, filter material surface is held back component and is increased gradually, filtering velocity declines, effluent quality variation, back flushing be need to carry out, when back flushing, water intaking valve and outlet valve closed, open backwash pump, water enters filtrate bed 3 by the water distribution system 6 of filter tank 7 lower ends, and filtrate bed 3 expands, between filtrate or filtrate and filter tank 7 inwalls, flow resistance plate 4 mutually collide, its surface biological film is come off, in ingoing stream.Backwashing water is closed backwash pump, opens the water inlet pipe 1 of filtrate bed 3 upper ends, and backwashing water is being carried the microbial film coming off secretly from water inlet pipe 1 is discharged filter tank 7.
After back flushing finishes, close backwash pump, valve and water inlet pipe 1, reopen water inlet pipe 1, filter tank 7 reruns.
