Embodiment 1

[0065] The water body algal pollution treatment was carried out in the Weijin River A area of ​​Tianjin. Drive the processing ship (vehicle unit) carrying the processing system into this area, and set up three detection points in this area, each 10 meters apart. The value is 272.7 µg / L, and the turbidity is 46.7 NTU. The control unit judges that the water quality exceeds the standard, and immediately starts the algae removal unit to add algaecide A (which contains diatomite, calcium carbonate, Sodium silicate and pullulan) were simultaneously stirred at a speed of 150 r / min for 5 min, so that the concentration of algaecide A at the detection point was 20 mg / L, and then algaecide B ( It contains polyacrylamide and polyaluminum chloride with a mass ratio of 1:0.2) and is simultaneously stirred at a speed of 50 r / min for 10 min, so that the concentration of algaecide B at the detection point is 20 mg / min. L. After 60 min, the detection unit was started again, and the measured c...

Embodiment 2

[0067] The water body algal pollution treatment was carried out in the B area of ​​Weijin River in Tianjin. Drive the processing ship (vehicle unit) carrying the processing system into the area, and set up three detection points in the area, each 5 meters apart. The value of chlorophyll a is 110.9 µg / L, and the turbidity is 23.5 NTU. The control unit judges that the water quality is up to the standard, and controls the processing ship to sail to the second detection point. The measured chlorophyll a value is 418.3 µg / L, and the turbidity is 67.4 NTU. The control unit judges If the water quality exceeds the standard, immediately start the algae removal unit to add algaecide A (which contains diatomite, calcium carbonate, sodium silicate and pullulan in a mass ratio of 10:4:0.8:0.2) and add algaecide A at 50 r / min The speed was synchronously stirred for 15 min, so that the concentration of algaecide A at the detection point was 50 mg / L, and then algaecide B (which contained poly...

Embodiment 3

[0069]Algae pollution treatment was carried out in a lake A area of ​​Tianjin University. Drive the processing ship (vehicle unit) carrying the processing system into the area, set up two detection points in the area, 12 meters apart, the detection unit firstly tests the water quality of the first detection point, and measures the chlorophyll a value It is 112.7 µg / L, and the turbidity is 22.1 NTU. The control unit judges that the water quality is not exceeding the standard, and controls the processing ship to sail to the second detection point. The measured chlorophyll a value is 302.5 µg / L, and the turbidity is 38.8 NTU. The control unit judges If the water quality exceeds the standard, immediately start the algae removal unit to add algaecide A (which contains diatomite, calcium carbonate, sodium silicate and pullulan in a mass ratio of 10:3:0.9:0.1) and add algaecide A at 250 r / min The speed was synchronously stirred for 2 min, so that the concentration of the algaecide A ...

Abstract

The invention discloses a treatment method and a treatment system for landscape water body algae pollution. The processing method comprises the following steps: (1) setting several detection points in the water area to be treated, with an interval of 5-15m between adjacent detection points, (2) detecting the turbidity and chlorophyll a value of a detection point, and judging The degree of algae pollution, (3) when the degree of algae pollution is above the predetermined value, carry out algae removal treatment at the detection point, (4) move to another detection point and repeat step (2) until all detection points are completed detection. The treatment method according to the present invention is suitable for emergency algae removal in closed slow-flow landscape water bodies such as urban rivers and lakes. It not only has high algae removal efficiency, but also can avoid secondary outbreaks of algae pollution.

Description

technical field [0001] The invention relates to the field of water biological pollution treatment, and more particularly, to a treatment method and treatment system for algal pollution in landscape water. 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. The algae multiply and grow continuously and rapidly, seriously destroying the balance and stability of the aquatic ecosystem, greatly affecting the health of water quality and water landscape, thus affecting the safety of people's domestic and drinking water. The main hazards are: algae consume a large amount of dissolved oxygen in the water body, making it difficult for fish to survive in the water; algal toxins released by algae will enter the human body through enrichment, endangering human health; the outbrea...
