High-efficiency environment-friendly desalted water production method

Abstract

The invention discloses a high-efficiency environment-friendly desalted water production method. According to the method, a raw water pool, a high-efficiency double-chamber cation bed, a decarbonization device, a high-efficiency double-chamber anion bed and a desalted water tank are sequentially connected by pipelines, wherein a high-efficiency fiber filter is arranged on a connecting pipeline between the raw water pool and the high-efficiency double-chamber cation bed, an intermediate water tank is arranged at the lower part of the decarbonization device, a water outlet of the intermediate water tank is connected with a water inlet of the bottom of the high-efficiency double-chamber anion bed, a water outlet at the top of the high-efficiency double-chamber cation bed is connected with an acid regeneration system, a water outlet at the top of the high-efficiency double-chamber anion bed is connected with an alkali regeneration system, and the waste liquor in the high-efficiency double-chamber cation bed, the high-efficiency double-chamber anion bed is connected to a neutralizing water tank through a pipeline, the desalted water in the desalted water tank is delivered outside to users, the water outlet of the desalted water tank is respectively connected with the acid regeneration system and the alkali regeneration system by a pipeline. According to the technology, the high-efficiency fiber filter, the high-efficiency double-chamber cation bed and the high-efficiency double-chamber anion bed are adopted, and novel fiber packing is used, so that the internal water supplementing mode, the resin ratio and the resin filling and regeneration mode of the double-chamber bed equipment are improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, and is especially suitable for a high-efficiency and environment-friendly desalinated water production method for large-scale chemical and power plants. Background technique [0002] At present, the desalinated water treatment methods are mainly the traditional ion exchange method and reverse osmosis membrane method. The traditional ion exchange method has been used in the desalinated water industry for decades, and is widely used in domestic power plants and chemical plants, but its There are problems such as large area, cumbersome operation, low flow rate, small water production, large cleaning water consumption, high acid and alkali consumption, short cycle, short resin life, and the need to re-neutralize acid and alkali waste liquid; desalination by reverse osmosis membrane method It was widely used and promoted in the domestic market in the late 1990s, but it has problems such as hig...
