2results about How to "Good separation and purification effect" patented technology

The utility model relates to the technical field of environment-friendly treatment of industrial sewage, in particular to a yellow phosphorus production sewage circulating purification system, which is provided with a yellow phosphorus sewage tank, a multi-stage sedimentation mechanism, a concentration filtering mechanism and a clear liquid collecting tank which are sequentially arranged along a sewage treatment flow, the yellow phosphorus sewage tank is used for collecting yellow phosphorus production sewage; the multi-stage sedimentation mechanism is provided with a plurality of deep cone sedimentation machines which are arranged in series and are used for carrying out sedimentation separation on the conveyed yellow phosphorus sewage; the concentrating and filtering mechanism is used for concentrating and separating the conveyed settling floating liquid; and the clear liquid collecting tank is used for collecting the clear liquid separated by the concentrating and filtering mechanism and conveying the clear liquid to the phosphorus collecting tower through a water conveying pipe. Aiming at the special characteristics of yellow phosphorus production sewage purification treatment, the utility model constructs a closed circulation purification system, has the technical characteristics of greatly reducing the occupied area, being low in construction and operation cost and excellent in separation and purification effect, and has remarkable technical effect and economic benefit.

The application of PCE-11 as a modifier in the flotation separation of brucite and serpentine relates to the field of brucite beneficiation and purification technology. This invention provides a flotation separation method for brucite and serpentine using PCE-11 as a modifier. By introducing PCE-11, the difference in floatability between brucite and serpentine during flotation is amplified, achieving effective separation of brucite and the gangue mineral serpentine. This invention has advantages such as high efficiency, low cost, no pollution, and simple process.
