Capillary wastewater treatment and desalination equipment and method

Abstract

The invention discloses capillary wastewater treatment and desalination equipment and a method. Capillary-like tubes which are arranged in order and are uniformly arranged are arranged inside the equipment, and the equipment consists of a concentrated water area, a submersion area, a vapor-water mixing area, a top vacuum area and a clean water area; the top vacuum area and the clean water area communicate with each other through capillary-like tube connection, and the concentrated water area is provided with a salt draining passage and is completely isolated from the bottom clean water area; microwave and ultrasonic devices are arranged outside; organic matters are degraded and removed under the action of microwave energy and ultrasonic energy; a vacuumizing device and an exhaust gas filtering device are arranged at the top of the equipment, the vapor-water mixing area maintains a certain negative-pressure state, pressure difference is formed between the inside and outside of the capillary-like tubes, and water molecules enter the tubes and flow into the clean water area under the action of the pressure difference; and formed concentrated water enters the concentrated water area, and the concentrated water and precipitated salts are discharged out of the equipment through a discharge pipe. According to the equipment, organic matter and salt removing systems are integrated, and the equipment is applicable to high-salt high-concentration organic wastewater of different types.

Description

technical field [0001] The invention belongs to the fields of energy saving, environmental protection and water treatment, and in particular relates to a capillary waste water treatment and desalination equipment and method. Background technique [0002] High-salt wastewater refers to wastewater with a salt content of more than 5% in the water. High-salt wastewater not only contains high salinity, but also contains a large number of organic compounds that are difficult to remove. High-salt wastewater is mainly produced in the chemical production industry. Due to the dissolution, absorption and washing of reaction products in the chemical production process, as well as the absorption of chemical tail gas, strong acids or strong bases are often used for treatment, resulting in a large amount of acid salts or alkaline salts. As a result, organic wastewater with high salt content is formed. Different chemical products and different production processes in actual production prod...
