The invention discloses an acid pickling circulation technology of high-purity quartz sand. Firstly a sieve pore separation plate needs to be sunken in supernatant acid pickling liquid, and mixed liquid prepared from sodium alginate, chitosan, cellulose and water is sprayed, the mixed liquid is cross linked in the acid pickling liquid to form a film structure, and the film can effectively adsorb metal ions and generated silicon tetrafluoride gas in the acid pickling liquid; and the used film can be subjected to simple treatment in a sodium hydroxide solution to reobtain the film formation mixed liquid and thus recycling is achieved. The content of silicon dioxide in the high-purity quartz sand obtained by adopting the acid pickling method related in the invention is no lower than 99.995%,the content of iron is no higher than 10ppm, the acid pickling liquid can still maintain a good acid pickling effect after being cyclically used for many times, the operation technology is simple, green and environmentally friendly, and zero emission of acid pickling pollutants is achieved.
