Embodiment

[0041] The reactor has a volume of 20 liters and is made of glued plexiglass plates. The height of the internal liquid level is 25cm, the width is 8cm (internal dimension), and the length is 100cm (internal dimension). The volume of each aerobic unit and anaerobic unit is 3.2L. The volume ratio is 1:5; the volume ratio between the ascending section and the descending section in the anaerobic zone is 5:1; an aeration zone is set at the outlet of the reactor so that the dissolved oxygen in the effluent can meet the discharge standard, and a settling zone is set at the same time to facilitate Observe the sludge generation of the system. In this experiment, total phosphorus is used as an indicator of sludge dissolution, because phosphorus is absorbed by microorganisms in the metabolic process and released during sludge dissolution, so the degradation of sludge can be estimated by measuring phosphorus; at the same time, the effluent is collected at the outlet, Measure the average ...

Abstract

The invention relates to a flow turning plate reactor and a method for implementing aerobic-anaerobic microbe repeated coupling sewage water processing by it, and it comprises cuboid, aeration device, isolation baffles, flow guide baffles, where one end of it is provided with water inlet and the other end is provided with water outlet, several vertical isolation baffles and flow guide baffles are arranged at the cuboid in the direction of water flow; and thus it implements repeated occurrence of aerobic unit with aeration device and anaerobic unit without aeration device in the direction of the water flow. And the sewage water enters from the water inlet into the reactor and goes through several aerobic-anaerobic unit couplings in the flow turning mode and finally is drained out of the reactor through the water outlet, thus the sewage is processed. And the invention can remove organic matters and nitrogen from the sewage water and save foundation construction and operation expenses.

Description

technical field [0001] The invention relates to a baffle reactor and a method for using the baffle reactor to realize repeated coupling of aerobic and anaerobic microorganisms to treat sewage, belonging to the technical field of water treatment. Background technique [0002] With the acceleration of my country's urbanization process and the continuous growth of population, the amount of sewage discharge is also showing an increasing trend. According to the long-term target outline of China's environmental protection, in 2010, the sewage treatment rate of cities designated as municipalities in the country shall not be lower than 60%, and the sewage treatment rate of key cities shall not be lower than 70%. To achieve this goal within five years, it is necessary to build a A large number of urban sewage treatment plants. At present, most urban sewage treatment plants use biological methods. Biological methods include activated sludge method and biofilm method. Activated slud...
