Abstract

The invention discloses a silicon dioxide aerogel doped scolecite water treatment agent and a preparation method thereof. The water treatment agent is prepared from the following raw materials in parts by weight: 0.1-0.2 part of triethylamine, 5-7 parts of silicon dioxide aerogel, 100-140 parts of scolecite, 1-1.3 parts of ammonium persulfate, 5-7 parts of glycidyl methacrylate, 3-4 parts of an amino silane coupling agent and 40-50 parts of acrylamide. Due to a synergetic treatment method with the silicon dioxide aerogel, scolecite powder and polyacrylamide, the water treatment agent is good in treatment effect, high in finished product stability, not liable to disperse, good in self-sedimentation effect and convenient to recycle; in addition, both the silicon dioxide aerogel and the polyacrylamide can be uniformly distributed into micro pore structures of the scolecite powder, so that not only is a flocculation effect improved, but also the water treatment agent is easy to clean, highin repeated use rate and convenient in treatment.

Description

technical field [0001] The invention belongs to the field of water treatment agents, in particular to a silica airgel doped calcium zeolite water treatment agent and a preparation method thereof. Background technique [0002] Green water treatment agent is currently a hot spot in research and development in the field of industrial circulating cooling water. Actively developing green water treatment agent suitable for China's national conditions not only has positive environmental significance, but also has important economic value; [0003] Currently, the commonly used water treatment agents on the market have relatively single functionality, and generally can only treat specific wastewater environments, and most of the water treatment agents on the market have elements that are harmful to the environment. Therefore, the purpose of the present invention is to provide A water treatment agent with good environmental protection, strong functionality, high stability and wide app...
