An Alternating Plug Flow Aerobic Biological Fluidized Bed Reactor

Abstract

The invention discloses an alternate plug flow aerobic biological fluidized bed reactor which comprises a reaction tank, wherein the interior of the reaction tank is divided into a settling zone A and a settling zone B propped against two side walls, a multifunctional zone A close to the settling zone A, a multifunctional zone B close to the settling zone B, and an aerobic fluidized bed reaction zone between the multifunctional zone A and the multifunctional zone B; aerating systems are arranged at the bottoms of the interiors of the multifunctional zone A and the multifunctional zone B; water distribution systems are arranged at the tops of the interiors of the multifunctional zone A and the multifunctional zone B; another aerating system is arranged at the bottom of the aerobic fluidized bed reaction zone, and a biocarrier loaded with aerobic bacteria is distributed in the aerobic fluidized bed reaction zone; a mud guard wall and fenders are arranged in each of the settling zone A and the settling zone B; a water outlet is formed in the bottom of each of the settling zone A and the settling zone B. The alternate plug flow aerobic biological fluidized bed reactor increases the contact area between microorganism and waste water, and is excellent in treatment effect, small in occupied area and low in energy consumption.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to an alternate plug flow aerobic biological fluidized bed reactor. Background technique [0002] With the continuous improvement of my country's urbanization process and people's living standards, environmental pollution has become a major obstacle to improving people's quality of life. The components of various industrial wastewater are becoming more and more complex, the amount of production is increasing, and the environmental standards are increasing. , it becomes more and more difficult to deal with. Seeking efficient and low-cost sewage treatment technology has become the goal and responsibility of environmental protection workers. [0003] A method of removing organic pollutants in wastewater by using the metabolism of microorganisms, also known as wastewater biochemical treatment, referred to as wastewater biochemical method. Due to the high cost and com...

Problems solved by technology

Therefore, regardless of the external circulating fluidized bed or the ordinary internal circulating fluidized bed, it is necessary to use power equipment to transport the lost carrier and bacteria, which increases the operating cost. At the same time, due to the special physical state of the carrier, the material of the pump flow part is proposed. High requirements and therefore high investment costs
