Problems solved by technology

Another example is the Guanting Reservoir, which supplies water to Beijing. Due to sedimentation and intermittent pollution of water sources, a grain of mouse droppings was formed and a pot of soup was destroyed. As a result, the Guanting Reservoir lost its function of drinking water diversion. Improve water quality and control pollution from the source

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] figure 1 The lower end of the single flexible water-proof curtain main body 1 is reinforced to strengthen the shear resistance, and the heavy-falling body 2 is arranged at the lower end of the flexible water-proof curtain main body 1. The heavy-falling body 2 is connected with the mud surface by the anchor system 3, and the flexible The waterproof curtain is fixed in the designated position. During use, the plurality of unit flexible water-proof curtain main bodies 1 are staggered and overlapped with each other to form a flexible water-proof curtain. The main body 1 of the flexible water-proof curtain is usually a film with a density lower than that of water, or a film with a density slightly higher than that of water. The upper end of the film is provided with buoyant facilities, such as airbags or buoys. The height of the flexible water-proof curtain is slig...

Abstract

The present invention discloses one simple, unique, efficient and cheap large area water pollution preventing and reducing isolation method. The technological scheme is to separate water of different pollution degree with mixing. Sewage is controlled to flow through separated water flow belt and has no pollution to large area water. The said method needs no biological and chemical additive added.

Description

technical field [0001] The invention relates to a method for environmental protection, more specifically, relates to a method for isolating polluted (muddy) water zones in large water areas such as rivers, lakes and reservoirs. Background technique [0002] With the continuous increase of population and the rapid development of industrial and agricultural production, the water environment on which human beings rely is constantly deteriorating. The performance is that sewage is continuously flowing into large areas of water such as rivers, lakes and reservoirs, making the water quality worse and threatening the majority of people at all times. The health of the people; sediment and sand, continuous siltation, shrinking lakes, affecting flood discharge and shipping benefits. At present, the restoration technologies for the water environment are mainly focused on: (1) building sewage treatment plants to control and reduce the amount of sewage from the ...
