| Abstract: | A certain amount of ammonium chloride are contained in the wastewater from the production of potassium carbonate by ion - exchange. The effective scheme and process design method for the wastewater treatment are made. Both jet pump and three effects vacuum evaporation are used in the technology route which can recover ammonium chloride . The defects, such as great consumption of energy and serious corrosion of equipment in the normal evaporation technology of abstracting ammonium chloride from low concentration ammonium chloride solution are overcome by using the new technology process. The new technology can not only solve the wastewater pollution to the environment, but also get remarkable economic benefit. |
