The invention relates to a purification
system for micro-polluted
raw water, comprising a stripping
oil separation tank, a coagulating
sedimentation tank, a coagulating chemical dosing device, a first middle water tank, a water feeding pump, a biological aerated filter, a second middle water tank, a coagulating chemical dosing unit, a filtering lift pump, a multi-
media filter, a
manganese sand filter, an
active carbon filter, an acid dosing device, a scale inhibitor dosing device, a mixer, a
reverse osmosis device, an alkali dosing device, a disinfection device and an
ultraviolet sterilization device. The purification
system for micro-polluted
raw water disclosed by the invention has the following advantages that: main pollutants are especially removed at first, and then a
reverse osmosis technology is used as a safety guarantee; the
reverse osmosis pre-treatment is designed adequately, and the operation of the
system is safe and stable, so that the occurrence frequency of
pollution and blockage phenomena is greatly decreased,
chemical cleaning period is greatly prolonged, and the recycling rate of water is up to 75%; and the purification system is suitable for the occasions of treating the drinking water of municipal administration, villages, industrial enterprises and mine fields or for the occasions of reusing the
reclaimed water which needs advanced treatment. The invention further refers to a purification method of the purification system for micro-polluted
raw water.
