Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] An integrated anaerobic rotary tubular membrane bioreactor is used to treat high-concentration aquaculture wastewater. Such as figure 1 As shown, the main body of the reactor used has a diameter of 20cm, a height of 60cm, and an effective volume of 12L. The tubular membrane module has a diameter of 10cm and a length of 16cm, including 9 membrane tubes arranged in a cross shape ( figure 2 ), the membrane tube is made of PVDF, with a diameter of 1.2cm, an effective length of 10cm, and an effective filtration area of 340cm 2 , The distance between the upper and lower liquid level gauges and the upper flange is adjusted to 5cm and 20cm respectively. The reactor is inoculated with domesticated anaerobic sludge equivalent to 1 / 2 of its effective volume, and then injected into the aquaculture wastewater. During the start-up stage of the reactor, the wa...

Abstract
The invention discloses an integrated anaerobic rotating pipe type membrane bioreactor and a running method thereof. The integrated anaerobic rotating pipe type membrane bioreactor mainly comprises a reactor body, a pressure control system, a tubular membrane assembly and a rotating device. The reactor body is composed of a top cover and a reactor box body. An exhaust port is formed in the top cover. The side of the box body is provided with a water inlet and a check valve. A water drainage opening and a sludge discharge opening are formed in the bottom of the box body. The pressure control system is composed of a pressure sensor and an automatic exhaust valve and is arranged at the exhaust port. The tubular membrane assembly is arranged in the reactor body. The upper portion of the tubular membrane assembly is connected with a transmission shaft of the rotating device, and the lower portion of the tubular membrane assembly is connected with a water outlet through a rotating shaft seal ring. The rotating device is arranged on the top of the reactor body. Pressure formed by gas generated in the anaerobic process in the closed reactor and liquid gravity serve as filter power of the tubular membrane assembly together, and controllable membrane filtration automatic flow water discharge is achieved. The integrated anaerobic rotating pipe type membrane bioreactor and the running method have the advantages of being simple in structure, convenient to operate, light in membrane pollution, low in running cost, and the like, and have high practical value.
Description
technical field [0001] The invention belongs to the technical field of water treatment with anaerobic technology as the main body, and in particular relates to an integrated anaerobic rotary tubular membrane bioreactor and an operating method thereof. Background technique [0002] Anaerobic bioreactor is an effective process that can treat high-concentration organic wastewater. Anaerobic bioreactors have strong impact resistance and are suitable for wastewater with high organic concentration. The energy consumption of the treatment process is lower than that of the aerobic process, and the methane gas produced can be used as energy recovery. [0003] The traditional anaerobic process often uses a three-phase separator to separate gas, mud and water. However, the structure of the three-phase separator is complex, the installation requirements are high, and the device takes a long time to start. The sludge flocs often flow out with the water flow, resulting in poor water outp...
