Abstract

The invention discloses a low-temperature vacuum evaporation wastewater treatment device, and aims to overcome the defects of high energy consumption and low automation degree of wastewater treatment.The device comprises a vacuum evaporation separator, a vacuum pump, a feeding pump, a steam condenser, a heat exchanger and a controller; the upper part and the lower part of the vacuum evaporation separator are respectively connected with a steam discharge pipe and a concentrated solution discharge pipe; the side wall of the vacuum evaporation separator is connected with a liquid inlet pipe, oneend of a steam condenser is connected with a steam discharge pipe, the other end of the steam condenser is connected with a vacuum pump, a heat exchange pipe is arranged in the steam discharge pipe,one end of the heat exchange pipe is connected with a feeding pump, the other end is connected with a heat exchanger inlet, a heat exchanger outlet is connected with the liquid inlet pipe, and the steam condenser is connected with a condensate recovery pipe; and the vacuum pump and the feeding pump are electrically connected with the controller. The low-temperature vacuum evaporation wastewater treatment device is low in wastewater treatment energy consumption, high in automation degree and good in evaporation and concentration effect.

Description

technical field [0001] The invention relates to a waste water treatment technology, more specifically, it relates to a low-temperature vacuum evaporation waste water treatment device. Background technique [0002] A large amount of waste water is produced in the process of industrial production. Since industrial waste water usually contains a large amount of toxic and harmful substances, which pollutes the environment and endangers human health, it is necessary to take corresponding purification measures for disposal before it can be reused or discharged. The main methods of wastewater treatment include chemical oxidation, extraction, adsorption, incineration, catalytic oxidation, biochemical method, etc., but only the biochemical method has mature technology, simple equipment, large processing capacity, and low operating cost, which is also the most widely used in wastewater treatment. broadest method. However, some wastewater cannot be biochemically treated due to its hig...
