这可能是因为高温条件下无机结垢更容易形成，同时一些金属离子会与有机物和EPS交联使得污染物凝聚更紧密，导致膜面的污染物不容易溶于碱性溶液。

This may be because inorganic scaling is easier to form under high temperature conditions. At the same time, some metal ions will be cross-linked with organic matter and EPS, which makes the pollutants condense more closely, resulting in that the pollutants on the membrane surface are not easy to dissolve in alkaline solution.
