Description
かかる目的を達成するために、本発明の固液分離膜の保管方法は、次のとおり特定される。
１． 活性汚泥と処理水を固液膜分離する装置内に設置されて使用された分離膜を乾燥状態で保管する際、分離膜を洗浄液により洗浄し、ついで、親水化剤を含む水溶液により膜面を親水化させた後、分離膜を乾燥し、保管することを特徴とする固液分離膜の保管方法。
２． 分離膜が設置されている固液膜分離装置の膜二次側から洗浄液を流入させて静置洗浄し、ついで、親水化剤を含む水溶液を膜二次側から注入して膜面を親水化させた後、分離膜を乾燥し、保管することを特徴とする、上記１記載の固液分離膜の保管方法。
３． 運転休止後に固液膜分離装置から取出された分離膜エレメントを、洗浄液に浸漬させて洗浄を行い、ついで、親水化液を含む水溶液に浸漬させて親水化させた後、乾燥し、保管することを特徴とする、上記１記載の固液分離膜の保管方法。
４． 親水化剤が、界面活性剤および多価アルコールからなる群から選ばれる少なくとも１つの薬剤である上記１〜３いずれかに記載の固液分離膜の保管方法。
In order to achieve this object, the storage method of the solid-liquid separation membrane of the present invention is specified as follows.
1. When the used separation membrane is stored in a dry-liquid membrane separation device that separates activated sludge and treated water, the separation membrane is washed with a cleaning solution, and then the membrane surface is washed with an aqueous solution containing a hydrophilizing agent. A method for storing a solid-liquid separation membrane, comprising drying and storing the separation membrane after hydrophilization.
2. The washing liquid is allowed to flow from the membrane secondary side of the solid-liquid membrane separation apparatus where the separation membrane is installed, and then left to clean, and then an aqueous solution containing a hydrophilizing agent is injected from the membrane secondary side to make the membrane surface hydrophilic. 2. The method for storing a solid-liquid separation membrane according to 1 above, wherein the separation membrane is dried and then stored.
3. The separation membrane element taken out from the solid-liquid membrane separation device after the operation stop is immersed in a cleaning solution for cleaning, and then immersed in an aqueous solution containing a hydrophilizing solution to be hydrophilized, and then dried and stored. 2. The method for storing a solid-liquid separation membrane according to 1 above .
4). 4. The method for storing a solid-liquid separation membrane according to any one of 1 to 3, wherein the hydrophilizing agent is at least one drug selected from the group consisting of a surfactant and a polyhydric alcohol.
