Embodiment 1

[0080] Example 1: Separation results of secondary effluent components from different water plants

[0081] Obtain secondary effluent from different water plants, filter with 0.45 micron filter membrane, carry out repeated tests according to the device and method established in this patent, and the obtained component separation results are shown in Table 2.

[0082] Table 2 Separation results of dissolved organic matter and hydrophilic and hydrophobic substances in the secondary effluent of different water plants

[0083]

[0084] As can be seen from Table 2, the automatic device and method for the separation of dissolved organic matter components in water established by this patent have better repeatability, and the obtained results are more reliable; the proportions of the components in the secondary water of different water plants are different, Therefore, the pre-membrane pretreatment process of the reclaimed water plant can select different treatment methods according t...

Abstract

The invention discloses an automatic device and method for separating dissolved organic matter components in water. Dissolved organic matter in water is separated into six components including HOA (hydrophobic acids), HOB (hydrophobic bases), HON (hydrophobic neutrals), HIA (hydrophilic acids), HIB (hydrophilic bases) and HIN (hydrophilic neutrals) with macroporous adsorption resin DAX-8, cation exchange resin MSC-H and anion exchange resin AIIIS, so that the representation of the dissolved organic matter in the water is more detailed, and the pollution characteristic is clearer. The device comprises a hydrophobic substance separation part and a hydrophilic substance separation part, can separate hydrophilic substances in the dissolved organic matter in the water automatically, continuously and conveniently, requires little maintenance and has high efficiency.

Description

technical field [0001] The invention belongs to the technical field of water treatment and utilization, and is a method for separating hydrophilic and hydrophobic substances of dissolved organic matter in water, in particular to an automatic device and method for separating components of dissolved organic matter in water. Background technique [0002] The shortage of water resources is becoming more and more serious, and in some places, recycled water has become an important second-largest water source. At present, reclaimed water plants generally use the secondary effluent of sewage plants as the water source, and use MF (UF) + RO double-membrane process to produce reclaimed water. However, the common membrane fouling and cleaning problems in the membrane process make the operation cost higher. Therefore, there is a need for an efficient analysis method for pollutants in water, which can distinguish different organic substances in the secondary effluent for quantitative an...
