Description

A suspended water body classification filter device

technical field

The invention belongs to the field of water resource utilization, relates to a water extraction and filtration technology for water bodies, and in particular relates to a suspension type water body classification filtration device.

Background technique

In the prior art, most of the water intake and filtration methods are to sink a large filter device into the bottom of the water containing a large amount of sludge, fix the filter device on the shore or float the filter device on the water surface. The above three types of filter devices have several problems. First, the problem of sinking the filter device into the bottom of the water is that the sludge is mainly deposited on the bottom of the water, which is easy to cause the water pump to fail. Moreover, the large and bulky filter device is not conducive to the later stage after sinking to the bottom of the water. Maintenance; the second is to float the filter on the water, ignoring that there is often a lot of garbage on the water. The above three types of filter devices ignore the distribution characteristics of water impurities. If a filter device suspended in water can be designed using the distribution characteristics of water impurities, the water around the device is relatively clean, which is equivalent to bringing a layer of water. Due to the effect of natural filtration, a water classification filtration device that can be suspended in water can be designed.
