Abstract

The invention belongs to the technical field of sewage treatment, and provides a sewage treatment method and device based on a hydrate water vapor adsorption method, and the device comprises a sewage evaporation area, a hydrate generation area, a hydrate decomposition area and a data acquisition and control system; water vapor rising by evaporation of sewage at normal temperature, condensate water and a hydrating agent react on a refrigeration wall surface to generate hydrates, continuous evaporation of the sewage is promoted, crystals are scraped to a lower collecting area by a scraper after being generated, and the hydrates are decomposed into fresh water to realize sewage treatment. The invention provides a method for treating complex wastewater containing various pollutants at the same time, water vapor is consumed to generate hydrate to promote sewage evaporation, and the obtained decomposed water does not contain pollutants theoretically. The sewage treatment method provided by the invention has the characteristics of simplicity in operation, low energy consumption and high efficiency, and the energy consumption of sewage treatment is effectively reduced; meanwhile, the gas hydrating agent is recycled, the sewage treatment cost is reduced, and the economic and environment-friendly benefits are improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment method and device based on a hydrate water vapor adsorption method. Background technique [0002] In recent years, with the rapid development of the economy and the acceleration of the industrialization process, the amount of sewage discharge has continued to increase, and sewage discharge has become an important obstacle to the construction of ecological civilization in my country. The average annual sewage discharge in my country reaches 70 billion tons, of which the average annual discharge of industrial sewage exceeds 20 billion tons, accounting for about 30% of the total sewage discharge. Industrial sewage has the characteristics of high pollution and difficult treatment, and is rich in various pollutants such as inorganic heavy metals, organic phenols, light hydrocarbons, etc., which greatly increases the difficulty of sewage treatment. The di...
