Abstract

The invention relates to a multifunctional water purifier and a preparation method thereof. The purifier comprises a metal salt water solution and a gel aqueous solution, wherein the volume ratio of the metal salt water solution to the gel aqueous solution is (1-3):1; the metal salt water solution is any combination of more than two of a ferric salt water solution, an aluminum salt water solution, a magnesium salt water solution and a calcium salt water solution; the gel aqueous solution is one of a gelatin water solution, an agar water solution and an xanthan gum water solution. The gelatinization properties of the metal salt and the gel are combined, so that the multifunctional water purifier not only has an efficient removal effect on pollutants such as chemical oxygen demand (COD), total protein (TP), NH3<->N and the like caused by the metal salt, but also has the advantages of gelling property, plasticity, loose porosity, biodegradability and the like of the gelling agent, simultaneously has the characteristics of being wide in application range, convenient to transport, easy to separate, high in utilization rate, free of harm to environment and the like, and can be repeatedly utilized.

Description

technical field [0001] The invention belongs to the technical field of water pollution treatment, and in particular relates to a multifunctional water quality purifying agent and a preparation method thereof. Background technique [0002] my country's water pollution problem is serious, and the discharge of sewage and waste water is about 1×10 per day 8 m 3 as much. At present, 82% of the rivers and lakes in the country have been polluted to varying degrees, and the annual economic loss due to water pollution is as high as 37.7 billion yuan. Water pollution comes from industrial wastewater, domestic sewage, non-point source pollution, etc. Due to the diversity and uncertainty of water pollution sources, water is seriously polluted, COD, TP, NH 3 -N and other indicators far exceed the emission standards stipulated by the state. The water purifier has the advantages of fast response and stable effect. At present, the more common ones in the environmental protection marke...
