Problems solved by technology

The secondary steam generated during the evaporation process is then condensed into condensed water with cooling water, and the heat energy in the secondary steam is transferred to the cooling water and then diffused into the air, resulting in waste of heat energy and consumption of cooling water

Embodiment Construction

[0030] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0031] The best embodiment of the treatment method of high-salt organic wastewater of the present invention adopts a mechanical vapor recompression evaporation system for wastewater treatment, which has the following steps:

[0032] ①Wastewater preheating: Wastewater is preheated at an absolute pressure of 57861-60313Pa to a boiling temperature of 81-82°C;

[0033] ②Primary evaporation: The preheated wastewater enters the first-effect evaporator 8 for heat exchange. The vapor phase temperature of the first-effect evaporator 8 is 78-79℃, the absolute pressure is 43837-45603Pa, and the liquid-phase temperature of the first-effect evaporator 8 is 81- 82°C, the t...

Abstract

The invention relates to a method for processing high-saline organic wastewater. A mechanical vapor recompression vaporization (MVR) system is adopted to process the wastewater, and the method comprises the following steps of: (1) preheating of the wastewater; (2) primary vaporization; (3) primary vapour-liquid separation; (4) secondary vaporization; (5) secondary vapour-liquid separation; (6) forced-circulation evaporation; (7) discharging; (8) secondary vapor recompression; and (9) circulation evaporation. Due to the adoption of the MVR system, the economic benefit can be improved remarkably, and enterprises can be helped to realize the aim of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of high-efficiency and energy-saving wastewater treatment, in particular to a treatment method and a treatment device for high-salt organic wastewater. Background technique [0002] High-salt organic wastewater has always been a difficult problem in wastewater treatment, and it exists widely in industries such as petroleum, chemical industry, food, waste liquid treatment, and intermediates. The usual aerobic anaerobic biochemical treatment cannot be used due to the restriction of bacterial salt tolerance (generally, the salt content needs to be less than 1%). Currently, multiple-effect evaporation treatment is mainly used. [0003] The processing cost of multiple effect evaporation is very high, and the organic matter is difficult to recover. Many organic substances are prone to polymerization at high temperature, resulting in foaming, which leads to abnormal evaporation. The evaporative concentration proc...
