This invention discloses a system and method for defluorination and ammonia removal from glass engraving wastewater. The defluorination and ammonia removal method includes the following steps: reacting glass engraving wastewater with an alkaline calcium-containing compound solution to produce a primary mixed liquid; reacting the primary mixed liquid with a fly ash suspension to obtain a secondary mixed liquid; subjecting the secondary mixed liquid to a flocculation reaction to produce a tertiary mixed liquid; filtering the tertiary mixed liquid to produce filtrate, neutralizing the filtrate with an oxalic acid solution, and then sequentially performing coagulation and flocculation reactions to produce a quaternary mixed liquid; subjecting the quaternary mixed liquid to sedimentation separation to produce a supernatant; and subjecting the supernatant to short-cut nitrification and denitrification treatment to produce a defluorinated and deammoniated supernatant. This invention uses fly ash to replace part of the slaked lime for defluorination, separates sludge and water through plate and frame filtration, adjusts the pH with oxalic acid, and adds coagulants and flocculants to achieve decalcification and hardening. The remaining oxalic acid provides a carbon source, and short-cut nitrification and denitrification are used for nitrogen removal, improving the defluorination and ammonia removal efficiency and reducing treatment costs.

This utility model discloses a laser engraving machine for glass engraving, including a base and a mounting plate. The front side wall of the mounting plate is equipped with a control panel and an electric slide rail. A drive mechanism is located within the electric slide rail. The base has a mounting groove containing an adjustment mechanism. Both ends of the adjustment mechanism are equipped with pressing mechanisms, and each pressing mechanism has a clamping mechanism at its top. The mounting groove contains two sliding grooves, each equipped with a blocking mechanism. This utility model has a reasonable structural design. By incorporating the blocking and drive mechanisms, it can automatically prevent glass debris from flying by raising the blocking plate through the displacement of the clamping plate before the operator begins engraving. Simultaneously, the drive mechanism allows the operator to adjust the height of the engraving head according to actual needs during use for fine processing.
