Field of the Invention The present invention relates to a water purifying apparatus using a separation membrane as a filtering agent and a method for cleaning the same, and more particularly to a technique for recovering a filtration flow rate which is lowered due to clogging of the separation membrane.

ている。2. Description of the Related Art At present, a water purification treatment using a separation membrane is called an hollow fiber membrane filter from an industrial field such as wastewater treatment using an ultrafiltration membrane and ultrapure water production using a reverse osmosis membrane. Household products such as water purifiers that use filtration membranes are widely used. However, in the case of filtration using a separation membrane, there is a problem that the filtration flow rate decreases due to clogging substances. Therefore, various methods have been proposed for removing the clogging substances adhering to and depositing on the surface of the separation membrane to recover the filtration flow rate.
【０００３】このような方法の一つは物理的な洗浄方法

物を洗い流す方法も提案されている。One of such methods is a physical cleaning method, for example, a method of flushing and removing the deposits on the membrane surface with running water as disclosed in Japanese Utility Model Laid-Open No. 56-2996. Is proposed. Further, by devising this, as disclosed in Japanese Patent Laid-Open No. 3-72990, a method has been proposed in which purified water is backflowed from the downstream side to the upstream side of the separation membrane to wash away the adhered substances.

反応させて除去する方法が提案されている。Another method is a chemical method,
For example, as disclosed in Japanese Patent Application Laid-Open No. 52-120978, there has been proposed a method of removing a clogging substance adhering to the surface of a separation membrane by reacting it with a chemical.

【発明が解決しようとする課題】しかし、上記の通り付
着物を洗い流す物理的な洗浄方法では、分離膜への付着
物が鉄錆のように粒子状の無機物の場合には洗浄効果が
高いが、実際は分離膜への付着物は有機物やゲル状の物
質と混在して粘着しており、このような場合は洗い流す
だけでは洗浄効果が小さく濾過流量が殆ど回復しないと
いう欠点があった。However, in the physical cleaning method of washing away the deposits as described above, when the deposits on the separation membrane are particulate inorganic substances such as iron rust, the cleaning effect is high. Actually, the deposits on the separation membrane are mixed with organic substances and gel-like substances and are sticky. In such a case, there is a drawback that the washing effect is small and the filtration flow rate hardly recovers only by washing.

在しなかった。Further, the chemical cleaning method of removing the adhered substances with a chemical agent can decompose and remove the sticky substances such as organic substances on the surface of the separation membrane, so that the cleaning effect is high, but it is originally necessary. In addition to the equipment for the separation membrane module, a device configuration is required to perform a series of cleaning processes such as cleaning agent injection process, cleaning process, and rinsing process, which complicates the device and makes the piping and cleaning facilities resistant to chemicals. However, there is a drawback that the cost is high. In this way, since the device mechanism becomes complicated and becomes large in size, and the price becomes high, it is common to dispose of a separation membrane type water purification cartridge having a separation membrane in household products such as a water purifier. None of the separation membranes could be washed and regenerated.
