Embodiment 1

[0020] Start the air extraction device 1, because the air extraction device is connected to the waste liquid tank 2, so the air pressure in the waste liquid tank 2 drops, and the organic waste liquid is pressed into the waste liquid tank 2 from the water inlet 3 by the atmospheric pressure through the water inlet pipe 4 . Start the heating device 5, the temperature of the waste liquid tank 2 rises, when the temperature rises and reaches the boiling point of substances such as ethylene glycol, the light components are vaporized and overflow from the bell collector 6, due to the addition of the bell collector One end is passed in the condenser 7, so the temperature drops, and the temperature of the heating device 5 is raised step by step with 10° C. until being raised to 105° C. Now the water liquid liquefies into water vapor, and overflows from the bell-shaped collector 6, passes through the condenser 7, liquefies into water containing a small amount of impurities, and collects...

Embodiment 2

[0022] Start the air extraction device 1, because the air extraction device is connected to the waste liquid tank 2, so the air pressure in the waste liquid tank 2 drops, and the organic waste liquid is pressed into the waste liquid tank 2 from the water inlet 3 by the atmospheric pressure through the water inlet pipe 4 . Since the filter device 14 is included in the device, the sundries therein can be filtered on the filter screen, and at the same time, because the filter device is detachable, when the filter screen needs to be cleaned, or when the filter screen is not needed, it can be It can be easily removed without affecting the normal use of other parts. Start the heating device 5, the temperature of the waste liquid tank 2 rises, when the temperature rises and reaches the boiling point of substances such as ethylene glycol, the light components are vaporized and overflow from the bell collector 6, due to the addition of the bell collector One end is passed in the conde...

Abstract

The invention relates to a method and device for treating organic wastewater. In order to solve the problems of high cost, complex process and the like during the treatment of the organic wastewater at present, the invention provides the method for treating the organic wastewater, and the method comprises the steps of 1, collecting an organic waste liquid; 2, gradually heating the organic waste liquid, and performing distillation purification; and 3 collecting pure water, and burning organic waste gas. The method is simple, convenient and easy to operate, so that excessive manpower and material inputs are not needed, the treatment cost of the wastewater is saved, wastes are changed into treasures, and the organic liquid can be reused.

Description

[0001] technical field [0002] The invention relates to a method and device for treating waste water, in particular to a method and device for treating organic waste water. [0003] Background technique [0004] Organic wastewater generally includes: hydrocarbons, halogenated hydrocarbons, alcohols and ethers, ketones and aldehydes, acids and esters, amides or nitriles, nitro compounds, heterocyclic compounds, water-soluble polymer compounds and organic metals compound. The indicators of wastewater concentration and harmfulness can be divided into physical indicators, chemical indicators and biological indicators. Physical indicators include temperature, color, smell, taste, and solid matter. Chemical indicators include biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC) and total oxygen demand (TOD). Among them, BOD5 and COD are the most widely used. The larger the value of BOD, COD, TOC and TOD, the higher the content of organic ...
