Problems solved by technology

Coagulation and sedimentation after pre-oxidation still need to add a large amount of coagulant to precipitate algae, the dosage is more than 40mg / L, and the cost is high
The air flotation tank requires a large amount of high-pressure dissolved air water, which consumes a lot of energy and has high operating costs

Embodiment Construction

[0017] The present invention is further described in conjunction with the accompanying drawings and examples. The pressure tank in the embodiment of the present invention adopts two parallel connections, such as figure 1 As shown, the present embodiment is composed of a water supply pump 1, two parallel pressure tanks 6 and 7, a mixing tank 21, a reaction tank 29, a sedimentation tank 36, an air compressor 18 and a dosing device, which are connected by pipelines , valve control.

[0018] The inlet and outlet of the water supply pump 1 are respectively connected with the water pump inlet pipe 2 and the water pump outlet pipe 3, the water pump inlet pipe 2 extends into the water source 4, and the water pump outlet pipe 3 is connected with two parallel pressure tanks 6 and the water inlet pipe 10 of the pressure tank 7 .

[0019] The pressure tank 6 and the pressure tank 7 have exactly the same structure. They are cylindrical airtight containers with hemispherical ends. There a...

Abstract

The invention relates to a water treatment system for removing algae by pressure strengthening and sedimentation coagulating and a water treatment method, belonging to the technical field of drinking water treatment. The invention is mainly characterized by using the water treatment system and method which apply pressure for pre-treating and carrying out the sedimentation coagulating to remove the algae in the water, so as to be suitable for removing the algae with a floating property, such as water bloom blue-green algae and the like, and other turbidity substances from water supply plants. After the algae are treated by pressure pretreatment, air bags of the algae are crushed to lose buoyancy, so as to be easily removed by a sedimentation coagulating method to obtain a good effect; a pre-oxidant does not need to be added into the water to kill the algae, and harmful substances including algae toxins and the like are not released into the water, so as to improve the water supply safety; the algae with the crushed air bags are easy to precipitate, and a large quantity of coagulant does not need to be added, so as to save medicaments; and less compressed air or pressure water only needs to be introduced into a pressure pot to improve the pressure of the whole pressure pot, and the energy consumption is low, so that the operation cost of water treatment is reduced.

Description

technical field [0001] The invention relates to a water treatment system and method for algae-containing water, in particular to a pressure-enhanced coagulation-sedimentation algae-removal water treatment system and water treatment method. A water treatment device and method for algae belongs to the technical field of drinking water treatment, and is suitable for waterworks to remove algae and other turbidity substances with floating characteristics such as algae blooms. Background technique [0002] Algae are common phytoplankton in lakes and reservoirs, among which cyanobacteria are the most common and most harmful. Bloom cyanobacteria generally refers to cyanobacteria that can float and gather on the water surface to form algae "floating films". In Taihu Lake, Chaohu Lake and Dianchi Lake, cyanobacteria account for more than 90% of the total algae. The reason why water bloom cyanobacteria can float to the water surface is because there are air sacs in the algae cells, w...
