装置の疲労度が高くなり装置の寿命を短くしていた。Conventional devices and their problems Conventional rapid filtration methods have had difficulty in stably removing suspended pollutants of about 30 microns or less. The development and practical application of a two-door filtration device for wastewater reuse, which was filed in patent application No. 203881, has made it possible to stably remove suspended pollutants with a size of 5 microns or more. However, because the metal microporous filter element of the S filtration device for wastewater reuse in the earlier application was used as a layer, clogging occurred frequently (and the metal microporous filter element had to be backwashed more frequently). However, this increases the fatigue level of the equipment and shortens the life of the equipment.

By using a micro filter element (classification), we were able to significantly reduce the frequency of clogging. In addition, this greatly reduces the use of washing waste liquid due to backwashing, and provides a reusable liquid with high liquid quality accuracy, which is the original 1-1 method.

向にスイッチしＬ濾過を行なわせる構成である。Structure of the Invention In order to achieve the above object, the liquid multilayer filtration device of the present invention is equipped with two or more metal microporous filter elements stacked in the same cylinder in descending order of pore diameter, and A pump is used to pressurize the polluted liquid, and the liquid is passed through two or more metal microporous filter elements in descending order of pore size, and then discharged as a liquid for reuse. In addition, if two or more metal microporous filter elements become clogged or clogged with contaminants, and the liquid discharge side is depressurized, the differential pressure switch senses this and pumps the recycled liquid in the opposite direction as shown above. Backwash each element for a few seconds in order from the smallest pore size of the press-fitted metal microporous filter element.
Each time, the polluted backwashing liquid is sequentially discharged from the outlet side of each element. Once backwashing is complete, the system is configured to switch to normal direction and perform L filtration.

Figure 1 is an overall flowchart according to an embodiment of the present invention, in which contamination flows from the sewage tank (①) through the coarse dirt strainer (②) and into each of the metal microporous filter elements of [phase] by the pump (②). The liquid is fed into the reuse liquid tank (■) and reused as a service liquid. ■■■ (When many floating pollutants adhere to the metal micro-perforated filter element Φ, it becomes clogged, and the differential pressure switch (■) detects a decrease in pressure. The three-way valve (■) Then, the three-way valve of ■ is switched to the backwash line, and the reuse liquid of ■ is press-fitted into the metal microporous filter element of ■ for a few seconds. After draining the pollutant liquid, close the valve ■ for a few seconds, and then backwash the metal microporous filter element ■ (same as the metal microporous filter element Φ) from the three-way valve ■. The polluted liquid is discharged for a few seconds.The metal microporous filter element (■■) is also backwashed in the same process, and after that, the three-way valve (■■) is switched back to the normal 7 filtration system.

Because the metal microporous filter element of the C filtration device for wastewater reuse in the patent application filed by the inventor with application number 62-2038 was single-layered, the number of times of clogging per unit time was high. , which increased the fatigue level of the entire system. By equipping multiple layers of metal microporous filter elements in descending order of pore size, the frequency of clogging is drastically reduced, creating a simple filtration system.
