Water-purification pretreatment system

Abstract

A water-purification pretreatment system removes raw water of suspended solids heavier in specific gravity than water before a water-purification treatment of raw water taken from a water source and the system includes a liquid cyclone configured for raw water to inflow thereto and to be swirled inside thereof to separate from raw water suspended solids heavier in specific gravity tan water, an inflow line connected with the liquid cyclone for raw water to be supplied to the liquid cyclone and configured for raw water being supplied to swirl inside the liquid cyclone, and an outflow line configured for raw water having suspended solids separated therefrom to outflow as pretreated water from the liquid cyclone, allowing for a reduced load on a treatment of solid suspended solids as a watertreatment for water purification plants.

Description

technical field [0001] The invention relates to a pre-treatment system for water purification. In the water treatment system of a water purification plant, suspended matter whose specific gravity is larger than water is removed in the front stage of water purification treatment. Background technique [0002] In water treatment, suspended matter or turbidity components contained in raw water are mainly treated by water purification treatments such as floc formation with inorganic coagulants, gravity sedimentation in sedimentation tanks, sand filtration, and ultrafiltration. [0003] use figure 1 An example of the water treatment system 100 using coagulation and sedimentation will be described. exist figure 1 In the shown water treatment system 100 , a water intake ground is installed in a river as a water source, and water is drawn from the river by a water intake pump 1 . The raw water taken in by the water intake pump 1 is sent to the water intake well 3 through the wate...

AI Technical Summary

Problems solved by technology

Therefore, there are problems in that the time required for the treatment needs to be increased depending on the amount of the inflowing suspended matter, and the cost required for the coagulant and the cost required for the sludge treatment also increase

[0011] In particular, in rivers and rivers during rainfall, for example, high turbidity such as 1,000 degrees or more may occur, and the treatment of the turbidity removal process may not be sufficient.

When such an overload occurs, there may be a problem that the water purification process becomes unstable by stopping water intake, etc. in some cases.
