The purification principle is to utilize the size of the gap formed by the molecular sieve to purify, and the purification principle is as follows: the molecular groups of the target purification components in the mixture to be purified have different sizes, and the molecular sieves matched with the sizes of the molecular groups of the target components are arranged according to the sizes of the molecular groups of the target components, so that after the molecular groups of the target components pass through the molecular sieves, the molecular groups of the target components are trapped by gaps formed by the framework structures of the molecular sieves due to the matching of the sizes of the molecular groups, for example, chain-shaped hydrocarbons can not flow into the next link due to the chain length clamped in the framework of the molecular groups, and phenyl compounds can easily pass through the framework gaps of the molecular sieves due to the square structure, thereby achieving the effect of filtering hydrocarbons in the organic mixed liquid by the molecular sieves. Thereby enabling the molecular sieve to capture the molecular clusters of the target component, and then the other remaining components continue to flow through the molecular sieve to the next process.

The filtering performance of the molecular sieve on different media can be obtained by testing, and in the field of industrial wastewater treatment, when one target medium is filtered, the target molecular sieve type matched with the target medium is usually required to be found out so as to effectively filter the target medium. In the process of searching for the target molecular sieve, if only a single molecular sieve is tested in one test, the filtering effect is checked, which inevitably results in repeated searching process and low efficiency. We therefore propose a molecular sieve testing apparatus.
