Abstract

The invention discloses a multiphase flow rotation foam separation device and a waste water / gas treatment technology using the device. The technology and the device are used for high-ammonia nitrogen sewage treatment, can be used for replacing the conventional technologies such as aerobiotic aeration, steam stripping, air stripping and the like and have the advantages that the upper limit concentration is not limited, the ammonia nitrogen removal rate is more than 95%, and the chemical oxygen demand (COD) cr removal rate is more than 98%. The device has multiple functions such as ammonia nitrogen dissociation reaction, air stripping and ammonia recovery, thus being capable of easily completing high-ammonia nitrogen waste liquid full-loop operation in a matching way and realizing 'zero emission' in deed. The device can be used for treating various industrial flue gases with high temperature, high sulfur, high humidity and high dust content, integrates the functions of cooling, desulfurating and dust removing, and has the desulfurization rate being more than 90% and the dust removal rate being more than 99%; and after multiple stages of multiphase flow rotation foam separation devices are connected in series, the effect of electric precipitation can be achieved, but the project investment and energy consumption are far lower than those of electric precipitation.

Description

technical field

[0001] The invention relates to a process for treating waste water and waste gas in the field of environmental engineering by using multiphase flow rotating foam separation technology and equipment. Background technique

[0002] At present, the types of sewage treatment processes used in my country mainly include the following types: traditional activated sludge treatment process, AB process, A / O and A2 / O process, hydrolysis-aerobic process, oxidation ditch process, SBR and its variant process, Biological aerated filter process, biological contact oxidation process, oxidation pond, BIOLAK and land treatment process. With the development of sewage treatment, a variety of sewage treatment processes have been applied in my country's sewage treatment plants, among which A / O, A2 / O and their deformation processes, oxidation ditch, SBR and their variant processes are the main ones. Other processes such as AB process, biological aerated filter, hydrolysis-aerobic proc...
