Problems solved by technology

The coagulation-sedimentation method has an advantage in that its process is relatively easy to carry out, but has a problem in that it takes 2 to 5 hours to settle the target object to be treated, thus increasing the scale and cost of tools and equipment
The advantage of the flotation separation method is that it takes 20 to 50 minutes to float the target object, so the work can be performed with 1 / 5 to 1 / 6 of the total amount of equipment used in the coagulation-sedimentation method, but the flotation The problem with the separation method is that an additional air compressor, scum removal device, etc. must be provided and a part of the floating scum will be immersed in the water when the process is carried out

Embodiment Construction

[0036] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0037] figure 1 is a schematic diagram showing a water pollution prevention and control system according to a first embodiment of the present invention. like figure 1 As shown, the water pollution prevention and control system according to the first embodiment of the present invention includes: a water inlet pump 32, which is arranged near the water inlet source 30 and extracts water from the water inlet source 30 (hereinafter referred to as raw water); The extracted raw water is sent to the fresh water reservoir 40 containing the raw water through the water supply line 34; the air injection unit 50, the coagulant injection unit 51, and the pH adjustment chemical agent injection unit 52 are used to inject air, coagulant and pH adjustment Chemicals are injected into the raw water flowing along the water supply line 34; an agitation device 36 is u...

Abstract

The present invention discloses a hydrocyclone flotation system comprising: a hydrocyclone body; air injection means for injecting air into water being supplied to the hydrocyclone body; drain water volume regulation means for regulating the volume of drain water discharged out of the hydrocyclone body to maintain a constant water level in the hydrocyclone body; suspended solids filtration means for taking suspended solids out of the hydrocyclone body, the suspended solids staying dispersed in water being supplied to the hydrocyclone body and then floating and gathering towards the vortex center of the water by the swirling flow of the water and air foam while the water passes through the hydrocyclone body. With such a hydrocyclone flotation system, a water pollution prevention system of the present invention can effectively treat suspended solids produced from a purification process of waste water, sewage, used water, etc., at a relatively low cost.

Description

technical field [0001] The present invention relates to a hydrocyclone floating separator for separating suspended solids from a liquid and a water pollution prevention and control system using the hydrocyclone floating separator. Background technique [0002] Recently, due to the increase of water pollution, more and more algae are generated in lakes or rivers, thereby causing various problems such as destruction of ecosystems and the like. However, since the algae are very widely distributed and in large numbers, it is unimaginable to thoroughly treat the algae with the existing technology. [0003] Methods of removing algae include using chemicals to kill the algae and using filter materials to filter out the algae. These two methods are convenient algae treatment methods. However, of the two methods, the former generates toxic chemicals and secondary pollution due to dead algae, while the latter is difficult to apply due to the slow process and high cost required.
