The invention discloses a method for recovering acid and alkali from viscose sodium sulfate waste liquor through a bipolar membrane electrodialysis way. The method is characterized by sequentially comprising the following steps of: crystallizing; adjusting pH (Potential of Hydrogen); initially filtering at the first time; oxidizing reducing substances through O3; initially filtering at the second time; removing organic substances through activated carbon; removing zinc ions through ion exchange resin; filtering and performing refined filtration through pp micropores; preparing acid and alkali; and concentrating. By adopting the method, the regenerative recovery rate of the acid and alkali in the viscose sodium sulfate waste liquor is increased, the damage of impurities in the waste liquor on a bipolar membrane is reduced, so that the service life of the bipolar membrane is prolonged, and the bipolar membrane electrodialysis and the subsequent processes can be able to be carried out smoothly.

The invention discloses automatic circulating equipment for perforating machine core rods. The automatic circulating equipment comprises a perforating machine is used for driving the corresponding core rod to penetrate a pipe material and further comprises a return roller way, a first material delivering mechanism, a second material delivering mechanism, a rod breaking-away roller way, a rod breaking-away device, a third material delivering mechanism and a fourth material delivering mechanism, wherein the return roller way is used for carrying the to-be-used core rod; the first material delivering mechanism is used for delivering the core rod on the return roller way into the perforating machine; the second material delivering mechanism is used for delivering the pipe material provided with the corresponding core rod in a penetrated manner to the rod breaking-away roller way; the rod breaking-away roller way is used for carrying the pipe material provided with the corresponding core rod in a penetrated manner; the rod breaking-away device is used for breaking the pipe material on the rod breaking-away roller way away from the core rod which is arranged in the pipe material in a penetrating manner; the third material delivering mechanism is used for delivering the pipe material on the rod breaking-away roller way to the next procedure; and the fourth material delivering mechanism is used for delivering the core rod on the rod breaking-away roller way to the return roller way.
