Specific embodiment
Hereinafter, explaining the water treatment facilities and water treatment system of present embodiment in detail.In addition, the size about attached drawing Ratio is exaggerated for ease of description, sometimes different from actual ratio.In addition, in the present specification, water will be utilized Processing unit improves the water of the water sources such as slave well, river or the pond of water quality extraction or rainwater is known as " raw water " or " treated water ". Also, the raw water for being enhanced water quality and purifying is known as " water purification ".
[water treatment facilities]
It is different from the developed countries such as Japan, in developing country, as the well water of raw water, the muddy object ingredient of tap water It is more, also, the case where being contaminated by bacterial, is more.Therefore, it is intended that purification as raw water well water, tap water come using demand It is higher.
On the other hand, can not stable supplying electric power the case where more developing country in, in order to also can when having a power failure Enough water, it is more the case where the water storing tank for being set to roof, balcony stores domestic water.For example, as shown in Figure 1, in development In country, water storing tank 120 is set on the roof of building 12, stores domestic water.First is connected on the top of water storing tank 120 The other end of one end of piping 140, the first piping 140 becomes the state for being dipped in well water.Also, it is provided in the first piping 140 For extracting the suction pump 170 of raw water (well water) from well.Also, the one of the second piping 180 is connected in the lower part of water storing tank 120 End, the other end of the second piping 180 are connected to the tap etc. of the inside of building 1.
The water level sensor of the water level for detecting the storage water inside water storing tank 120 is equipped in the top surface of water storing tank 120 121.Water level sensor 121 is for example able to detect scheduled low water level WL and scheduled high water level (full-water level) WH the two water Position.Also, suction pump 170 works according to the output of water level sensor 121.That is, being detected in water level sensor 121 In the case where low water level WL, suction pump 170 is turned on, and well water is extracted via the first piping 140, to water storing tank 120 Supply.
Also, in developing country, purification be stored in water storing tank 120 storage water and as domestic water come using. For example, making it to be held in solid chemicals guarantor as shown in Fig. 2, calcium hypochlorite etc. is fixed as tablet shape and solid chemicals are made The state of the inside of gripping member 130 suspends in midair from the top surface of water storing tank 120 and is impregnated in storage water.Then, make the solid chemicals of dipping It gradually dissolves, purified treatment is carried out to storage water.But in purified treatment shown in Fig. 2, solid chemicals holding is needed replacing Part 130 and regularly supplement solid chemicals to water storing tank 120, but water storing tank 120 is set to the roof 2 of building 1, therefore solid Confirmation, the replacement of the surplus of medicament are very many and diverse.
On the other hand, the capacity of water storing tank is usually 300L~2000L, very big and very heavy, therefore can not be easily It is set to roof, the balcony of building.In addition, can be also somebody's turn to do to bearing even if being provided with water storing tank when water storing tank becomes canful Roof, the balcony of water storing tank apply biggish load-carrying load, it is therefore desirable to improve the bearing of building.Also, water storing tank is not Inexpensively, therefore as a result, the people other than high income group (rich stratum) is more the case where not being available water storing tank.
Therefore, in recent years, cheap automatic pump is universal, and low-income group selects automatic pump, therefore the use of water storing tank is gradually It reduces.That is, as shown in figure 3, be not provided with water storing tank on the roof of building 12, the suction pump used as automatic pump 170 extraction well water and as domestic water come using.In addition, such automatic pump is the pump for being built-in with pressure switch, pump only exists It works when opening tap.
In this case, as shown in figure 4, considering that liquid preparation feeder 190 is arranged in the downstream of suction pump 170, rigid It has just extracted well water and has put into the chlorine system medicaments such as aqueous sodium hypochlorite solution later.Liquid preparation feeder 190 includes: chlorine pharmacy jar 191, It is used to keep the chlorine system medicament of liquid；And medicament supply pipe 192, chlorine pharmacy jar 191 and the first piping 140 are connected, For from chlorine pharmacy jar 191 to 140 conveying chlorine system medicament of the first piping.Liquid preparation feeder 190 further include: constant displacement pump 193, It is set to medicament supply pipe 192, for supplying the chlorine system medicament of predetermined amount.In liquid preparation feeder 190, medicine can be utilized Agent supply pipe 192 and constant displacement pump 193 inject the chlorine system medicament of predetermined amount from chlorine pharmacy jar 191 to raw water.
However, the constant displacement pump 193 of the chlorine system medicament for injecting predetermined amount from chlorine pharmacy jar 191 to raw water is needed according to stream Amount critically controls chlorine injection rate, furthermore, it is desirable to chlorine-resistant countermeasure, therefore price is higher.Therefore, even high income group also without Method easily uses constant displacement pump 193.
In addition, as shown in Figure 5, it is also considered that replace liquid preparation feeder 190 using solid reagent dissolving device 200.Gu Body medicament dissolution device 200 is such as can be set as such as flowering structure: have the solid chemicals as calcium hypochlorite are fixed as tablet shape and At solid chemicals be held in internal solid chemicals holder 131, raw water can be made to contact with solid chemicals.In addition, solid Medicament holder 131 is able to use bypass piping 150 and is connected to the first piping 140.
Herein, as the water treatment facilities for having solid reagent dissolving device 200, various devices are proposed, but are substantially Solid chemicals are made gradually to be dissolved in the device of the recycling water in pond.Such water treatment facilities can be to treated water continuously Supplying medicament, but to more a small amount of treated water discontinuously supplying medicament, exist can not be finely controlled by The possibility for handling the drug concentration of water to purify.For example, a part for making solid chemicals be impregnated in treated water and for administration In the case where the device of agent, chlorine can be continuously fed to large-scale bathing pool as pond.But to more a small amount of For treated water discontinuously in the case where supplying medicament, there are following possible: when the circulation of water stops, solid chemicals are excessively molten For solution in treated water, drug concentration is increased to the degree of needs or more.
Even in addition, will not become solid chemicals be impregnated in always treated water state device, make it is processed Water direct circulation is in the case where the device of granular drug, to more a small amount of treated water discontinuously supplying medicament In the case of, however it remains the possibility of degree more than drug dissolution needs.
In this way, can not be finely controlled processed in the case where making solid reagent dissolving using previous such device The drug concentration of water purifies, there are the concentration of drug be increased to need more than degree possibility, therefore existing can not conduct Domestic water comes using such problems.
