TECHNICAL FIELD OF THE INVENTION
The present invention relates to a novel constant use method for effectively using resource water, which obtains service water having different water qualities from the same or a plurality of water zones from at least one well having a plurality of multistage water veins as a sampling aquifer. The present invention relates to a water sampling and distribution system and a device thereof.
[0002]
[Prior art]
Conventionally, as a countermeasure against spring water in construction work, it is commonly used as a temporary construction method in civil engineering work such as the deep well method of digging and pumping multiple wells or the well point method targeting the water level of relatively shallow stratum. I have.
On the other hand, Japanese Patent Application Laid-Open No. 7-62669 discloses a device for pumping by stratification from a plurality of aquifers in order to reduce the pumping cost for the same purpose. There has been proposed an improvement method from a countermeasure side in maintenance means for clogging due to adhesion of a particle size.
[0003]
On the other hand, Japanese Patent Application Laid-Open No. 9-41869 discloses a construction method for selectively sampling groundwater from a plurality of aquifers in a single well.
According to this publication, sampling from aquifers with different depths conventionally required a great deal of time in groundwater quality surveys, but according to this proposal, the sampling casing was improved to facilitate this. Content.
Furthermore, for the purpose of groundwater pollution survey, investigation of groundwater retained thermal energy, and groundwater treatment accompanying ground excavation work, etc., it is a device that individually pumps groundwater from multiple aquifers existing underground. Japanese Patent Application Laid-Open No. Hei 10-259797 is reported as a proposal in which the water shielding mechanism at the time of water sampling is devised.
[0004]
As described above with examples, all of them show examples of water sampling from multiple groundwater aquifers, but the purpose is to propose groundwater investigation or pumping involving civil engineering work, The present invention is a field that is fundamentally different in its purpose and configuration, and in its point of view.
That is, in the era of diversification of water demand, in order to effectively utilize groundwater from the viewpoint of energy saving and resource saving, the purpose is different from a plurality of groundwater aquifers held by at least one former well. The present invention relates to a new water distribution system and a device for cultivating a water use field and utilizing the water effectively as resources.
[0005]
[Means for Solving the Problems]
The present inventors have studied diligently to achieve the above-mentioned object from such a viewpoint, and examined the required water quality of each water, for example, a drinking water field, an intermediate water field, a greening / garden water field, The primary purpose is to collect water from each aquifer by application field. That is, in the field of drinking water, groundwater in the deep water zone existing at a depth of 150 to 200 m, which is advantageous in terms of water quality, and in the field of medium water, groundwater in the middle water zone existing at a depth of 100 to 120 m, greening and It has been found that, as garden water, groundwater in a surface water zone existing at a depth of 50 to 80 m is basically preferable.
[0006]
The second object of the present invention is to improve the target water quality by performing water treatment by an appropriate measure, although the effective water extraction amount differs depending on the groundwater zone and the water quality fluctuates when the underground depth differs as described above. Thereby, the intended use range can be expanded. At the same time, a self-backup system can be established.
That is, among various types of groundwater obtained from each of these groundwater aquifers, for example, by upgrading to a drinking water level by applying an appropriate water treatment means, a plurality of water that can be sampled from at least one same starting point is obtained. There is an advantage that a self-backup system can be built by utilizing raw water.
The present invention was completed after taking into account the conditions based on such a goal and incorporating it as the backbone of each water distribution system and completing a comprehensive study.
[0007]
That is, the gist of the present invention is that in a sampling well having a plurality of multistage water veins as a sampling aquifer, at least two stages of sampling areas are provided to individually sample water, and then directly to water distribution. Or a water distribution system after simultaneous treatment, if necessary, and then water distribution.
[0008]
In addition, in the above water sampling area, at least one stage of drinking water quality and / or unsuitable water quality is simultaneously sampled, and further, when water is individually sampled from the water sampling area, a specific part water strainer function is provided. A well water simultaneous multi-stage water sampling and distribution system characterized by employing the well pipes provided.
On the other hand, the raw water obtained from each of the sampling wells from the plurality of multi-stage water veins can be supplied in place of another intended supply water by performing an appropriate treatment in accordance with the water quality. It is also a feature of the present invention to provide an emergency water distribution system that can cope with an unforeseen situation of a predetermined target water sampling well, in conjunction with the established city water supply.
[0009]
In the present invention, it is important that a sampling aquifer having a plurality or multi-stage water veins as a sampling aquifer has a target aquifer capable of sampling. For this purpose, it is assumed that a drilling geological survey at the underground depth is conducted in advance, and at least the permeable layer and the impermeable layer can be clearly confirmed by exploration using an electric logging device.
In normal cases, the geological formation that can be used as a water source is checked by drilling at the site to be explored, conducting a geological survey and measuring the specific resistance (Ω · m) of the geological material at each depth using a boring geological column map created. An analogy of an aquifer that can be watered.
[0010]
In the present invention, the drinking water suitable area is raw water that is directly provided with drinking water quality in the water quality collected from the target water collecting aquifer, but by performing some kind of water treatment. There is also raw water that is potable. In the present invention, any case in which such drinking-quality raw water can be collected is an object of the present invention.
At the same time, raw water that is not suitable for drinking is utilized as non-potable water as non-potable raw water. In addition, potable quality raw water that is not subjected to water treatment can be similarly used as non-potable water.
[0011]
Further, in the present invention, the water production obtained by controlling the quality of the raw water obtained from each of the water sampling wells from the plural or multi-stage water veins can be used for water other than the originally intended field. This means, in other words, for example, that if it is a raw water that can be made into drinking-quality water by applying appropriate water treatment, for example, it can be diverted to drinking water in the field of drinking water other than the purpose as treated water in an emergency. .
In this way, by utilizing the multi-stage effective water vein even in a single sampling well, in the field of water quality, especially in the field of drinking water, it is possible to complete a self-backup system within the sampling range within the same well pipe. There is one of the features of the present invention.
[0012]
In the present invention, various methods are employed for producing drinking water from raw water that can be taken for drinking. A typical example is a precision filtration filter incorporating a filter medium mainly composed of a microporous filtration membrane. One of the features of the present invention is that it can be dealt with by a filtration device that employs.

【Example】
Example 1
A 5.5 KW submersible pump is attached to each well pump P1 shown in FIG. 2, a 5.5 KW submersible pump is attached to P2, and a 5.5 KW submersible pump is attached to P3, and each is 100 L / min, 100 L / min, 80 L / min. Minutes were pumped from each well. In all cases, the raw water is transparent in appearance. According to the system shown in the flow sheet of FIG. 5, a 12-liter sodium hypochlorite solution was prepared in a 200-liter chemical tank for each process, and sterilized in conjunction with each raw water pump by a 16-W chemical injection pump. It is set so that the agent is injected.
Except for the raw water in the first water zone, water treatment was performed in parallel with the sterilization treatment. Therefore, the raw water in the first water zone (a) was pumped up by the well pump (P1) and then received in the raw water tank and sent by the 1.5 KW water distribution pump (P4).
[0021]
In addition, the raw water in the second water zone (a) is pumped by a well pump (P2), received in a raw water tank, and further transferred to a sand filter tank by a 1.5 kW raw water pump (P5) for filtration. Thereafter, the water was introduced into a treatment water tank and water was supplied by a 1.5 KW water distribution pump (P7). In this state, operation was performed continuously for 24 hours, and sample water before and after the treatment was collected.
Further, the raw water in the third water zone (c) is pumped up by a well pump (P3), received in a raw water tank, and further transferred to a sand filtration tank and a membrane treatment device by a 1.5 kW raw water pump (P6). Then, after the rough filtration and the high-precision filtration treatment, the mixture was introduced into a treated water tank and fed with a 1.5 kW water distribution pump (P8).
In this state, each of them was operated continuously for 24 hours, sampled water was sampled before and after raw water treatment except for the first water zone, and the sampled water was analyzed. The results are shown in Table 1 below.
