Environment-friendly water treatment agent capable of removing ammonia and nitrogen

Abstract

The invention provides an environment-friendly water treatment agent capable of removing ammonia and nitrogen. The water treatment agent is prepared from the following raw materials: nitrosomas, polyacrylamide, sodium dodecyl-benzenesulfonate, nekal, polyferric chloride, sodium hydroxide, sodium hypochlorite, zeolite, zinc hydrogen phosphate, magnesium dihydrogen phosphate, aluminum hydroxide, magnesium hydrate and phosphoric acid. A preparation method of the environment-friendly water treatment agent capable of removing ammonia and nitrogen comprises the following steps: a, weighing polyacrylamide, sodium dodecyl-benzenesulfonate, nekal, polyferric chloride and deionized water, then adding the materials into a stirrer, and uniformly stirring; b, successively adding sodium hydroxide, sodium hypochlorite, zeolite, zinc hydrogen phosphate, magnesium dihydrogen phosphate, aluminum hydroxide and magnesium hydrate into the stirrer, and uniformly stirring; c, adding nitrosomas into the stirrer, and uniformly stirring; and d, adding phosphoric acid into the stirrer, and uniformly stirring to obtain the treatment agent. The environment-friendly water treatment agent capable of removing ammonia and nitrogen is low in cost and high in removal efficiency of ammonia and nitrogen, and is suitable for extensive popularization.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an environment-friendly water treatment agent for removing ammonia nitrogen. Background technique [0002] In recent years, the intensification of water pollution, the improvement of drinking water quality standards and the enhancement of people's environmental awareness have brought severe challenges to the field of drinking water treatment in my country. Ammonia nitrogen pollutants are ubiquitous in my country's source water, and it has become one of the main pollutants in drinking water treatment due to the difficulty of removing them by conventional water treatment processes, especially the ammonia nitrogen in the low temperature period is even more difficult to treat. [0003] At present, the removal methods of ammonia nitrogen in drinking water treatment mainly include physical chemical method and biological method. (1) Breakpoint chlorination method is...
