Second embodiment
The present invention also provides a laminated filter comprising the filter laminated sheet 6 of the first embodiment, and the structure, the working principle and the beneficial effects of the filter laminated sheet 6 are the same as those of the first embodiment, and are not described herein again.

When the first filter unit 7 and the second filter unit 8 need to be backwashed, the process is similar to the above process, and will not be described again. The laminated filter provided by the invention has the advantages that when the back flushing operation is carried out, the filtering operation is uninterrupted, and the intermittent supply of clear water can be ensured. In actual operation, the number of the filtering units is not limited to three, and the specific number is determined according to actual needs.

The foregoing is merely a few embodiments of the present invention and those skilled in the art may make various modifications or alterations to the embodiments of the present invention in light of the disclosure herein without departing from the spirit and scope of the invention.
