The application discloses a kind of bio-based abrasive, including adsorptive abrasive 25-35 parts by weight, additional weight material 10-25 parts;Tensile fiber 25-40 parts, adhesive 10-15 parts, binder 25-50 parts, defoaming agent 2-5 parts, polishing powder 10-20 parts.A kind of bio-based abrasive preparation method, including step one, using adsorptive abrasive to make adsorptive abrasive particles;Step two, the adsorptive abrasive particles and additional weight material mixed are made;Step three, additional weight abrasive particles, defoaming agent, binder, polishing powder, tensile fiber are all put into mixing equipment and mix;Step four, the mixed material is placed into mold heat pressing solidification, forms bio-based abrasive.Preparing adsorptive abrasive particles, and adsorptive abrasive particles and additional weight material are combined, additional weight abrasive particles are made, and additional weight abrasive particles can improve the sedimentation rate of wear powder, reduce the harm of dust to human body.In addition, binder uses bio-based resin binder, reduces the generation of waste gas in processing and use process.

This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater recycling and treatment system for deionized water production. It includes a wastewater tank and a finished water tank, with a sedimentation device and a filtration device installed between them. A resin softener and a concentration device are also installed between the wastewater tank and the finished water tank. Wastewater in the wastewater tank sequentially passes through the sedimentation device, filtration device, resin softener, and concentration device before flowing into the finished water tank. This utility model, by adding a resin softener and a concentration device to the existing sedimentation and filtration devices, constructs a multi-stage treatment system of "sedimentation-filtration-softening-concentration," deeply removing impurities from the wastewater and improving the water resource recovery rate.
