Method for comprehensively treating river channel water ecology through photocatalysis
The invention discloses a method for comprehensively treating river channel water ecology through photocatalysis. The method comprises steps as follows: 1), upstream and downstream ranges of a to-be-treated river channel are determined, dams are built on the river channel respectively, and an upstream dam (3.1) and a downstream dam (3.2) are formed; 2), water insulation barriers (4) are arranged along banks of the river channel (1) in the downstream direction from a drain port (2), and a diversion trench (5) is formed between each water insulation barrier (4) and the corresponding river bank; 3), a microorganism contact oxidation area (6), a first photocatalysis area (7) and a first floristic area (8) are sequentially distributed in each diversion trench (5); 4), second photocatalysis areas (9) are distributed in a main river channel behind the upstream dam, and photocatalytic nets are further arranged in the second photocatalysis areas (9), and second floristic areas (10) are distributed on two sides of the main river channel. The isolation treatment method is adopted, so that the condition that the treatment difficulty is increased due to dilution of sewage at the drain port is effectively prevented, and the treatment cost is saved.
