Water treatment system based on reverse osmosis technology and treatment method thereof

Abstract

The invention belongs to the technical field of water treatment, and discloses a water treatment system based on reverse osmosis technology and a treatment method thereof. The water treatment system comprises a raw water pipe, a filtration treatment unit, an ion softening device, a reverse osmosis device and a water purification tank which are sequentially connected according to a water treatment sequence; the filtering treatment unit comprises a rear circulating aeration tank, wherein a water inlet of the rear circulating aeration tank is communicated with the raw water pipe, and a water outlet of the rear circulating aeration tank is communicated with the ion softening device; and a first partition plate and a second partition plate which are parallel to each other and are spaced are longitudinally arranged in the rear circulating aeration tank. The device is combined with the reverse osmosis device, a water body is subjected to circulating aeration in the rear circulating aeration tank under the action of gas stripping through the rear circulating aeration tank, the circulation of the water body in the tank is large, the liquid flow rate is high, and the transmission rate of oxygen can be improved; the water body in the rising inner cavity is disturbed through rotary aeration, and gas and liquid are fully mixed, so that the utilization rate of oxygen and the proliferation rate of microorganisms in the oxygen are improved, and the aeration effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a water treatment system based on reverse osmosis technology and a treatment method thereof. Background technique [0002] Water is the basic and strategic resource for human survival and development. Since the reform and opening up, China has made great progress in social economy, which has attracted worldwide attention. one of the most serious challenges. For this reason, attaching importance to water treatment and environmental governance technologies, and continuously researching solutions to water resource utilization, water conservation, and sewage and wastewater treatment are important measures to achieve sustainable economic and social development, and have practical and strategic significance. [0003] The reverse osmosis technology is to pass the raw water through a fine filter, a granular activated carbon filter, a compressed activated carbon filte...
