Abstract

The invention relates to a water trash-removal method by trash rack and floating mat net technology. According to its flowing law in water, trash is cleared step by step in trash rack system. Semi-sinking trash, obstructed by secret pile for trash rack in water, rushed slowly at lower part under the influence of continuous flowing dash, is cleared by person din boat. While trash at water surface sequentially goes forward, it is hold up by trash rack and floating mat net which has the separation angle angle beta corresponding to river bank. Water flows through mesh of trash rack and floating mat net and under trash rack and floating mat net, while trash, sequentially going in various direction under the effect of apparent force of water flowing and rebound force generated by water flowing net, is finally collected to the setting ideal trash-removal position, left from water by human or mechanical power and carried away by dirt-wagon. There are merits that less consuming, high clearing ratio for trash and so on.

Description

Technical field:

[0001] The invention relates to a water decontamination method using the technology of sewage blocking floating net, which is suitable for water decontamination of large and small hydropower stations, drinking water supply projects, pumping and drainage projects, water decontamination and purified water beautification of large rivers and rivers project. Background technique:

[0002] At present, in large and small hydropower stations, drinking water supply projects, pumping and drainage projects, etc., the iron fence decontamination methods adopted all use iron fences to stop the dirt, and then remove it manually or mechanically (decontamination machine). Due to the high flow velocity, the dirt staying on the iron fence seriously affects the passage of water. Sometimes the difference between the upper and lower water levels is tens of centimeters. If the dirt is removed manually, it needs to be shut down to remove it, which seriously affects the power genera...
