Abstract: The present disclosure relates to the technical field of wastewater treatment, and provides a wastewater treatment method and apparatus based on hydrate-based water vapor adsorption. The apparatus includes a wastewater evaporation zone, a hydrate formation zone, a hydrate decomposition zone, and a data acquisition and control system. Rising water vapor and condensed water formed during evaporation of wastewater at normal temperature react with a hydrate former on a cooling wall surface to form a hydrate, continuous evaporation of the wastewater is promoted, the hydrate is scraped off to a collecting zone below by a scraper after being formed, and the hydrate is decomposed into fresh water, thereby realizing wastewater treatment. The present disclosure provides a method for treating complex wastewater containing a plurality of pollutants, where water vapor is consumed to form the hydrate to promote wastewater evaporation, and water obtained from the decomposition does not contain pollutants theoretically.

Abstract: The present invention belongs to the field of gas solubility measurement, and provides a measuring device and method for gas solubility in a natural gas hydrate solution system. The measuring device mainly comprises a reaction system, a sampling system and a data analysis system. The present invention can be used for measuring gas solubility in a natural gas hydrate solution system at different temperature, pressure and salt ion conditions, and exploring influence of different environmental conditions on the gas solubility when hydrate-liquid water biphase equilibrium is achieved. The present invention in characterized in that the structure is simple, the operation is easy, sampling is carried out at a constant pressure to avoid damage to phase equilibrium and dissolution equilibrium of the systems, and a microfilter is used to ensure that a liquid sample taken does not contain hydrate crystals, so that experimental data has a relatively high accuracy.
