| titleOfInvention | Industrial reverse osmosis membrane device pollutant online extraction and analysis method |
| abstract | The invention relates to an industrial reverse osmosis membrane device pollutant online extraction and analysis method. The invention belongs to the field of membrane-method sewage deep processing and recycling method. The method comprises the steps that: a commercial reverse osmosis membrane is used for manufacturing a lateral line membrane assembly which serves as a key pollutant extraction carrier; the lateral line membrane assembly is connected in parallel into an industrial reverse osmosis membrane device; lateral line membrane assembly water-access valve opening degree is adjusted, such that inlet water membrane-surface flow velocity is controlled; during an operation process, lateral line membrane assembly water production variation is recorded with timed frequency; when water production is reduced by 50-95% relative to an initial water production, the polluted reverse osmosis membrane reaches an analysis requirement; the polluted reverse osmosis membrane is fetched and is subjected to pollutant observation and analysis; acid and alkali are respectively used for soaking and washing the polluted reverse osmosis membrane; and contents of specific pollutants in the washing liquid are detected. The method provided by the invention has high practicality. With the method, original industrial membrane assembly and operation conditions are not damaged, and reverse osmosis membrane pollution cause can be rapidly searched. Therefore, a good technical prospect is provided for long-term stable operation of actual industrial membrane devices. |
