XNH-03 macroporous ion exchange resin

XNH-03 macroporous ion exchange resinAbnormal phenomena and handling methods:

1. After the resin is contaminated by microorganisms, it can be soaked in less than 1% hydrogen peroxide solution and washed with water.

2. When the resin loses water and dries, it can be soaked in ethanol and then washed with water.

3. When the resin is contaminated with iron, it can be soaked in a 4-10% hydrochloric acid solution and then washed with water until neutral.

Precautions for use:

1. During transportation and storage, the temperature should be maintained at 5-40 ℃ to avoid overheating or overcooling. Be careful not to dry the resin to prevent changes in the pore structure.

2. Resin is loaded into the adsorption column for use. Before loading, the equipment pipeline should be cleaned to prevent harmful substances from contaminating the resin (such as iron pollution)

3. Before introducing the liquid into the resin bed, impurities should be removed, clarified, and filtered to avoid contaminating the resin.

4. If the resin column is not in use for a long time, it should be thoroughly decomposed and cleaned before shutdown, and soaked in ethanol or a salt solution greater than 10% to prevent bacteria from breeding in the resin. The experimental study on phenolic resin wastewater with volatile phenols at 1156 mg/L and formaldehyde at 2814 mg/L shows that the alkaline hydrolysis condensation ozone catalytic oxidation biochemical treatment process is feasible. The removal rate of formaldehyde reached 99.87% after 45 minutes of lime reaction at 65 ℃; Under normal temperature and pressure, with a pH value of 9 and a hydrogen peroxide dosage of 1 g/L, and an ozone dosage of 2000 mg/L, the removal rate of volatile phenols is 96%; After neutralization and dilution, it can meet the emission standards through biochemical treatment. Pre treatment experiments were conducted on the composition and characteristics of amino wastewater, including static separation, extraction, addition of urea for formaldehyde removal, and distillation for alcohol removal. The purpose is to recover usable components from wastewater while reducing the concentration of CODcr in the wastewater. According to the experimental results, it is feasible to directly distill and remove alcohol under alkaline conditions. It can recover about 5% to 7% of alcohol and remove over 80% of CODcr.
