Embodiment Construction
[0036] The technical solution of the present invention will be described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 Shown, according to one embodiment of the present invention, a kind of organic wastewater treatment system comprises:
[0038] The heater 302 is used to heat the mixed liquid of the organic waste water to be treated and the circulating liquid to form a primary mixed steam; the evaporator 301 is arranged in communication with the heater 302; it is used to conduct the primary mixed steam Gas-liquid separation forms secondary mixed steam and mixed concentrated liquid; part of the mixed concentrated liquid is used as circulating liquid; wherein, the evaporator 301 is arranged on the upper part of the heater 302 . The first steam compressor 303, the first steam compressor 303 communicates with the evaporator 301 through the first steam outlet pipe 103, and the first steam compressor 303 communicates with th...

The invention discloses an organic wastewater treatment system which comprises a heater, an evaporator, a first vapor compressor, an organic matter stripping tower, a second vapor compressor and a reboiler, wherein the evaporator is connected with the heater; the first vapor compressor is communicated with the evaporator through a first vapor outlet tube; the first vapor compressor is communicated with the heater through a first vapor inlet tube; the organic matter stripping tower is communicated with a first condensate collection tank; the second vapor compressor is communicated with the organic matter stripping tower through a second vapor outlet tube; the reboiler is communicated with the organic matter stripping tower; the reboiler is communicated with the second vapor compressor through a second vapor inlet tube. By adopting the organic wastewater treatment system, requirements of external vapor can be reduced, energy utilization rates and economic benefits are increased, requirements of extra circulation cooling water is reduced, water resources are saved, and organic wastewater treatment cost can be lowered.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an organic wastewater treatment system and method. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Since the composition of industrial wastewater is more complex, and some are toxic, industrial wastewater treatment is more difficult and more important than urban sewage treatment. Especially in chemical, pesticide, pharmaceutical and other synthetic or fermentation product production facilities, due to the complexity of chemical and biochemical reactions, a large amount of high-concentration organic wastewater is often accompanied. [0003] High-concentration organic wastewater mainly has the characteristics of high concentration of organic matter and com...
