Problems solved by technology

[0002] Due to the cumulative eutrophication in the long-term water quality and the small ecological cycle of the fixed water, it is especially suitable for the growth of algae, which reduces the dissolved oxygen in the water body and destroys the ecological balance. Water facilities are prone to clogging, etc.
In order to overcome the growth of algae, chemicals have been used all the time, which is not only inconvenient, but also has a certain impact on water quality and environmental protection. In recent years, micro-electrolytic algicides, electronic water processors, ozone, ozone / ultrasonic and O 3 / uv is used to kill algae and inhibit algae, but due to large equipment, large investment, and high cost, it is still in a small-scale application and test for algae killing and algae inhibition

Embodiment 1

[0023] To kill algae in the water body, the DC voltage is controlled at 8V, the anode of the electrode is brass, the cathode is copper, and the distance between the two electrodes is 2 cm, and they are directly placed in the water body. When the copper consumption reaches an average water body of 5mg / L, stop the electrolysis. After 10 days, the comparison culture water samples before and after treatment were tested. The untreated chlorophyll alpha was 113.3, and the treated chlorophyll alpha was 2.73. Continue to observe the water body for one month without algae growth.

Embodiment 2

[0025] In the spring treatment of raw water for domestic use, a set of electrodes is installed at the outlet of the suction pump, with a DC voltage of 36V and an interval of 2.5 cm between the two electrodes. They are placed directly in the water body, and the amount of treated water is 35 m 3 / KW, the copper consumption is 175 grams, the equivalent copper concentration is 5mg / L, and the raw water is 80% lower than the untreated bacteria count.

Embodiment 3

[0027] During the winter treatment of domestic raw water, a set of electrodes is installed at the outlet of the suction pump, with a DC voltage of 36V and an interval of 2.5 cm between the two electrodes, directly placed in the water body, and the treated water consumes 58.5 m 3 / KW, the copper consumption is 175 grams, and the equivalent copper concentration is 3mg / L.

Abstract

The present invention discloses algae killing and inhibiting method for water body. Electrolysis equipment is set on vehicle, boat, floated apparatus, cooling tower system or other apparatus near thewater body, and the electrodes are contacted with water body. The anode is made of copper material, and the cathode material is copper, iron, aluminium, graphite or other conductive material. The copper density in the water body is 0.4-4 mg / L for inhibiting algae and 3-8 mg / L for killing algae. Produced copper hydroxide is exhausted to water body continuously or intermittently to kill or inhibit algae. The said method can be used for killing and inhibit algae and bacteria without producing environmental pollution.

Description

Technical field: [0001] The invention relates to the technical field of water treatment in environmental protection, in particular to the algae killing, algae inhibition, bactericidal, bacteriostatic and fluid or non-fluid rivers, lakes, and coastal water bodies of raw water for cooling circulating water, swimming pool water, and tap water. Algae, anti-algae. Background technique: [0002] Due to the cumulative eutrophication in the long-term water quality and the small ecological cycle of the fixed water, it is especially suitable for the growth of algae, which reduces the dissolved oxygen in the water body and destroys the ecological balance. Water facilities are prone to clogging, etc. In order to overcome the growth of algae, chemicals have been used all the time, which is not only inconvenient, but also has a certain impact on water quality and environmental protection. In recent years, micro-electrolytic algicides, electronic water processors, ozone, ozone / ultrasonic ...
