Problems solved by technology

When the water source is polluted, algae multiply quickly in summer, and large areas of the water surface will be covered by algae, which will block the sunlight and isolate the process of oxygen dissolving in the water, causing fish, shrimp and plankton to suffocate due to lack of oxygen, resulting in Huge economic and environmental losses
At present, there are various algicides available in the market, but there are common problems of complex production process and high price, which have not been popularized and used, so that the problem of cyanobacteria pollution in water bodies has not been treated for a long time.

Embodiment 1

[0016] In the shallow water area where the wind and waves are small, the aqueous solution of the present invention can be evenly poured into the water. In order to cover an area of ​​500 square meters, about 700 kg of the present invention needs to be used, and the concentration is 30% to 50%. After entering the water, it can absorb and wrap algae and sundries, so that it sinks under a load, and its density increases by about 10% for every 1 meter it sinks. After 6 to 8 hours, a soft layer of 1 to 2 mm thick is formed on the bottom of the water, which makes the algae unable to carry out photosynthesis and die. Dead, it can remove 80%-95% of algae and about 40% of ammonia and nitrogen in water. Sprinkling should be carried out in pieces during use to avoid unnecessary damage to fish.

Embodiment 2

[0018] In deep water areas with strong wind and waves, it should be evenly sprinkled at 3-4 meters underwater to avoid waves and undercurrents. Calculated by covering an area of ​​500 square meters, it needs to use about one ton of the present invention, and it will form on the bottom of the water after 12 to 24 hours. A soft thin layer with a thickness of 2 to 3 mm. The purpose of increasing the dosage is to increase the weight of the thin layer and prevent the water flow from washing away the thin layer, which will affect the algae killing effect.

Abstract

The present invention relates to water treating engineering, and is especially one kind of algae scavenger for water. It is powder finer than 100 mesh and water soluble. After spread into water, it forms floc attached to the surface of various kinds of algae, so that algae deposits to form soft layer in the bottom of water and lacks of photosynthesis to die and the water become clear. The present invention has the beneficial effects of high algae eliminating effect, high safety and reliability, and being suitable for killing algae in lake, river, pond, fish farm and reservoir.

Description

Technical field: [0001] The invention relates to water treatment engineering, in particular to a water body algae scavenger. Background technique: [0002] In recent years, with the intensification of surface water pollution and eutrophication of water bodies, many lakes and reservoirs in my country, such as Dianchi Lake, Taihu Lake, Chaohu Lake, Dianshan Lake, etc., have been forced to stop water supply due to the stench of water quality caused by the proliferation of blue-green algae. When the water source is polluted, algae multiply quickly in summer, and large areas of the water surface will be covered by algae, which will block the sunlight and isolate the process of oxygen dissolving in the water, causing fish, shrimp and plankton to suffocate due to lack of oxygen, resulting in Huge economic and environmental losses. At present, various algicides have been supplied in the market, but the production process is complicated and the price is high, and they have not been ...
