Whole-membrane-process water treatment integration device

Abstract

The invention discloses a whole-membrane-process water treatment integration device. The whole-membrane-process water treatment integration device is characterized in that 'whole-membrane-process' water treatment components are integrated into a small-size device, and comprise a raw water pump, an ultra-filtration safety filter, an ultra-filtration membrane component, an ultra-filtration water tank, an ultra-filtration backwashing water pump, reverse-osmosis high-pressure pumps, reverse-osmosis membrane components, a fresh-water tank, an EDI (Electrodeionization) water feeding pump, an EDI membrane block, an acid dosing device, an alkali dosing device, a bactericide device, a scale inhibitor device, a reducing-agent device, a valve, pipelines and a PLC (Programmable Logic Control) control system; the ultra-filtration device consisting of the raw water pump, the ultra-filtration safety filter and the ultra-filtration membrane component, the ultra-filtration water tank, the first-stage reverse-osmosis high-pressure pump, the reverse-osmosis membrane component, the second-stage reverse-osmosis high-pressure pump, the second-stage reverse-osmosis membrane component, the fresh-water tank, the EDI water feeding pump and the EDI device are connected by the pipelines in the following sequence till the desalting water is discharged; and the ultra-filtration backwashing waterpump is arranged to be connected with the ultra-filtration membrane component for backwashing; and the acid dosing device, the alkali dosing device and the bactericide device are respectively connected to the ultra-filtration device.

Description

technical field [0001] The invention relates to a desalinated water treatment device, which can realize automatic operation of the device through an automatic control system, remove colloids, particles, germs, dissolved solids, etc. in water, and the effluent water quality index is better than the secondary desalinated water standard (ie Conductivity (25℃)<0.1μS / cm, silicon dioxide (SiO 2 )<20μg / L). The device is mainly used for pilot tests of enterprise-level water treatment projects, laboratory research of scientific research institutions and educational institutions. Background technique [0002] With the development of science and technology, water treatment technology is no exception. On the road of water treatment technology, it has experienced three generations of water treatment process development. The first generation process is filter + cation exchanger + carbon remover + anion exchanger + mixed ion exchanger. The second-generation process is filter (doub...
