Embodiment 1

[0065] Water algae pollution treatment in area A of Weijin River in Tianjin. Drive the processing ship (vehicle unit) carrying the processing system into this area, set three detection points in this area, each 10 meters apart, the detection unit first conducts water quality detection on the first detection point, and measures chlorophyll a The value is 272.7μg / L, and the turbidity is 46.7NTU. The control unit judges that the water quality exceeds the standard, and then starts the algae removal unit to add algaecide A (which contains diatomaceous earth, calcium carbonate, Sodium silicate and pullulan) and carry out synchronous stirring at a speed of 150r / min for 5min, so that the concentration of algaecide A at the detection point is 20mg / L, then add algaecide B (which contains mass Polyacrylamide and polyaluminum chloride at a ratio of 1:0.2) and synchronously stirred at a speed of 50r / min for 10min, so that the concentration of algaecide B at the detection point was 20mg / L. ...

Embodiment 2

[0067] Water algae pollution treatment in area B of Weijin River in Tianjin. Drive the processing ship (vehicle unit) carrying the processing system into this area, set three detection points in this area, each 5 meters apart, the detection unit first conducts water quality detection on the first detection point, and measures chlorophyll a The value is 110.9μg / L, the turbidity is 23.5NTU, the control unit judges that the water quality is up to standard, and controls the treatment ship to sail to the second detection point. The measured chlorophyll a value is 418.3μg / L, and the turbidity is 67.4NTU. The control unit judges If the water quality exceeds the standard, immediately start the algae removal unit to add algae remover A (which contains diatomaceous earth, calcium carbonate, sodium silicate and pullulan with a mass ratio of 10:4:0.8:0.2) and at a speed of 50r / min Carry out synchronous stirring 15min, so that the concentration of the algaecide A at this detection point po...

Embodiment 3

[0069]Water algae pollution treatment was carried out in area A of a lake in Tianjin University. Drive the processing ship (vehicle unit) carrying the processing system into this area, set up two detection points in this area, 12 meters apart, the detection unit first conducts water quality detection on the first detection point, and measures the chlorophyll a value The chlorophyll a value was 112.7μg / L, and the turbidity was 22.1NTU. The control unit judged that the water quality did not exceed the standard, and controlled the treatment ship to sail to the second detection point. The measured chlorophyll a value was 302.5μg / L, and the turbidity was 38.8NTU. The control unit judged that If the water quality exceeds the standard, immediately start the algae removal unit to add algaecide A (which contains diatomaceous earth, calcium carbonate, sodium silicate and pullulan with a mass ratio of 10:3:0.9:0.1) and at a speed of 250r / min Carry out synchronous stirring 2min, so that t...

Abstract

The invention discloses a landscape water algae pollution treatment method and a system. The treatment method comprises the following steps: (1) setting a plurality of detection points in a to-be-treated water area, wherein the distance between every two adjacent detection points is 5-15m, (2) detecting the turbidity and chlorophyll a value of one detection point and judging the algae pollution degree, (3) removing algae at the detection point when the algae pollution degree is more than a preset value, and (4) moving to another detection point and repeating the step (2) until the detection ofall the detection points is completed. The treatment method is suitable for emergency algae removal of closed slow-flow landscape water bodies such as urban rivers and lakes, the algae removal efficiency is high, and secondary outbreak of algae pollution can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more specifically, to a method and system for treating landscape water algae pollution. Background technique [0002] In recent years, with the development of cities and industries, human production and living activities have caused a large amount of organic or inorganic nutrients such as nitrogen and phosphorus to enter the surrounding water bodies. Excessively high concentrations of nutrient salts have caused serious eutrophication of the water body, resulting in water pollution. Algae multiply and grow rapidly, which seriously damages the balance and stability of the aquatic ecosystem, greatly affects the health of water quality and water body landscape, and thus affects the safety of people's domestic water and drinking water. Its main hazards are as follows: algae consume a large amount of dissolved oxygen in the water body, making it difficult for fish in the water to survive; algal...
