Apparatus and method for treating river and lake water

Abstract

A device for processing water of river and lake and its method are disclosed. Its filtering cartridge includes four ones arranging in a circle, with pipes connecting each one adjacent and there is separating surface in the upper and middle of it, above which is the cleaned water tank with a U-typed foam exhausting pipe linking to the water feeding pipe of filtering cartridge, and the other end of the pipe is extended into the foam-exhausting tank whose lower part is linking to the dirty-exhausting exit; each water feeding pipe of filtering cartridge is linking to a support jacket pipe, and an sleeve-typed exhausting device is supported by four support jacket pipes, whose bottom is linked with a water feeding pipe and V-typed water channel placing among the inner and outer inner sleeve, there is water curtain formed on the bottom edge and two upper ones. Besides, time register can be installed on the foam-exhausting pipe for automatic washing. The machine needs no human to operate has small volume, exhausts foams water effectively, saves energy and water source, suitable for dealing with pollution of river and lake.

Description

(1) Technical field [0001] The invention relates to a water treatment filtering device and a method thereof, in particular to a river and lake water treatment filtering device and a method thereof. (2) Background technology [0002] While the current rapid economic development has also brought about serious pollution of rivers and lakes. The existing river and lake water treatment methods, such as the Haihe "separation of salty and fresh water, clear and turbid flow" project, first cut off all the sewage entering the river, make it flow to the sewage treatment plant for treatment, and then introduce clean water from the upstream or rely on atmospheric precipitation. Supplementing river water to restore river water and achieve ecological balance is also the practice of other countries such as Europe. However, my country has a large population and severe water shortage, and there has been a situation where there is no water to draw. The existing method of using bacteria to t...
