The algae control device 35 comprises a known algae control device, and a pair of copper ion eluting electrode bodies made of a copper material are provided in a sterilizing water passage which is disposed so as to face each other at a predetermined interval. It is configured to sterilize algae and bacteria in water by allowing a direct current to flow between a pair of copper ion eluting electrode bodies and elution of copper ions into the water to be treated (such water Examples of the sterilization treatment device of JP
The one disclosed in Japanese Laid-Open Patent Publication No. 133194).

This algae control device 35 includes the algae control casing 3
It is fixed to the bottom plate of No. 1 and its inflow port 36 is connected to the outlet 27 of the filtration unit 20 via the connecting pipe 38, and the outflow port 37 is open in the algae control unit casing 31.

INDUSTRIAL APPLICABILITY The present invention is equipped with a submersible pump as described above, and is provided at the bottom of a pond or the like so as to absorb the pond water directly from the water intake port of the apparatus itself, and the filtered water to the pond or the like from the water discharge port. Since it is characterized by direct water discharge, it eliminates the need for a water conduit between the filtration device and the pond as in the past, and builds a mechanical room for the filtration device in the surrounding land such as the pond. Can be omitted.

Therefore, the site for installing the apparatus is not required, and the total installation cost of the filtration equipment including the installation work cost can be significantly reduced. Further, the pump capacity corresponding to the water pipe can be reduced, and the operation and maintenance cost can be reduced.

Also, by installing the device in a pond, noise is prevented and the landscape of the pond is not impaired. Furthermore, since the casing of the device is formed separately from the pump part, the filtering part, and the algae preventive part, and integrated, there is an effect that the device can be easily transported, installed, and maintained.
