High-brine zero discharge treatment device

Abstract

The invention discloses a high-brine zero discharge treatment device which comprises an evaporation tank, a second tank body and a first tank body, the upper end surface of the first tank body is in threaded connection with a closing lid in a closing way, the closing lid is provided with a water inlet pipe communicating with the interior of the first tank body, a filter box is placed in the firsttank body, the second tank body is welded on the lower end surface of the first tank body, a water tank is fixed in the second tank body, one side of the water tank is fixedly provided with a first membrane assembly, one side of the first membrane assembly is fixedly provided with a second membrane assembly, the first membrane assembly is provided with a first water outlet pipe communicating withthe second membrane assembly, a separation plate is welded under the water tank, a motor is fixed on the separation plate, the output shaft of the motor passes through the separation plate and is fixedly connected with a stirring rod, the evaporation tank is fixed below the separation plate, and a heating tube is installed on the inner wall of the bottom end of an evaporation box. The high-brine zero discharge treatment device of the invention has the advantages of capability of filtering and adsorbing organic substances to prevent fouling of the membrane assemblies and increasing the evaporation speed to accelerate the crystallization efficiency.

Description

technical field [0001] The invention relates to the technical field of high brine treatment equipment, in particular to a high brine zero discharge treatment device. Background technique [0002] High salt water also exists in China's coastal areas, such as sea estuaries, estuaries and other shallow sea areas. It is a classic sea salt water and has generally been seriously polluted. Another type of high-salt water is the concentrated wastewater discharged from industrial and mining enterprises after the implementation of waste water recycling. Once these high-salt waste water is discharged outside, it will cause great pollution to the environment, resulting in soil compaction, salinization, and damage to crops in the discharge area. The deterioration of the ecological environment and so on. Existing high-salt water zero-discharge treatment devices will cause membrane fouling, increase cleaning, and affect membrane flux and water recovery when the presence of organic matter ...
