(1) The most important advantage is its ability to treat various types of difficult-to-treat wastewater, especially those containing toxic heavy metals. Take electroplating wastewater as an example; its composition is very complex. In addition to oxygen-containing (CN-) wastewater and wastewater with varying pH levels, heavy metal wastewater represents a category of wastewater that poses significant hazards in the electroplating industry. Using diatomite as a raw material, the heavy metal ions in this wastewater can be removed through chemical transformations, turning them into insoluble metal salts. This process transforms toxic substances into non-toxic ones, harmful substances into harmless ones, allows for the recovery of valuable metals, and enables the reuse of water – all in one step. Currently, resource recycling and closed-loop systems are the main trends in development. (2) It has an excellent effect on degrading organic matter, and can remove a small amount of floating oil and emulsions. Textile printing and dyeing wastewater contains large amounts of dyes, starch, detergents, and other chemical agents; the dyes are often in a colloidal state. Treating this wastewater with diatomite not only reduces its color intensity but also removes suspended solids (SS) as well as organic substances such as COD and BOD, while also adjusting the pH of the liquid. (3) The flocculation and sedimentation occur rapidly; the sediment has a low moisture content, high density, and good dewatering properties, making it easy to treat by pressure filtration. The solid substances in municipal wastewater treatment plant sludge are mainly colloidal particles that have a strong affinity for water; without proper treatment, dewatering becomes very difficult. By adding this diatomaceous earth water treatment agent to the sludge, the flocculation and sedimentation process is accelerated, allowing the sludge to coagulate and thereby improving its dewatering properties as well as the density of the sludge bed. (4) The use of a single diatomite water treatment agent is sufficient to effectively treat various types of wastewater. Moreover, the wastewater treatment facilities and processes are simple and easy to operate, which greatly reduces the initial investment required for construction; at the same time, the operating costs are also low. (5) The sludge produced from wastewater treatment serves as an additive in agricultural fertilizers, enhancing their effectiveness, as diatomite is originally an important fertilizer additive. It can also improve the soil. It achieves the effect of moisturizing and keeping warm. Thereby completely eliminating secondary pollution.
