Embodiment 1

[0017] Example 1: Granular sludge cultivation of GMBR

[0018] Add activated sludge to the reactor, control the pH between 7.0 and 8.5, and the system COD volume load is between 0.5 and 2.0 kg / m 3 Change between .d, control the amount of aeration, and intermittently drain the finely divided sludge from the drain. After 3-4 days, the polymer with a relatively compact structure appears, and the aerobic granular sludge gradually appears after 8 days. On this basis, by controlling the amount of aeration and sludge discharge, the flocculent sludge with poor settling performance is continuously washed out, and the granular sludge is mainly used in the reactor. After determining the effect of aerobic granular sludge in the reactor on the COD and NH in the wastewater 3 -N has a better treatment effect.

Embodiment 2

[0019] Example 2: Comparison of GMBR effluent water quality with relevant national standards

[0020] The effluent quality of domestic sewage treated with GMBR is better than the standard of water reuse (toilet flushing and vehicle flushing) formulated by the state and relevant departments.

Abstract

The invention relates to an aerobic granular sludge film bioreactor system used for treating organic wastewater, which pertains to the technical field of wastewater treatment. The system is a water treatment system which effectively combines an aerobic granular sludge technique in a bio-treatment method with a film bioreactor technique and solves film pollution which is the most outstanding problem during the operation of the film bioreactor. The water treatment system has high capacity and load, good liquid-solid separation effect, fast sedimentation of sludge in a granular shape, high reactivity, light film pollution degree and long service life and occupies less land and nitration and denitrification can be carried out synchronously. The system can be applied to water reuse in communities and buildings, treating wastewater in hospitals and night soil wastewater, carrying out advanced treatment of high concentration of various organic industrial wastewaters, landfill / composting leachate treatment and micro-polluted drinking water purification.

Description

Technical field [0001] An aerobic granular sludge membrane bioreactor system for treating organic wastewater belongs to the technical field of wastewater treatment. Specifically, it is a water treatment system that effectively combines the aerobic granular sludge technology in the biological treatment method with the membrane bioreactor technology. The water treatment system has a high volume load, a small footprint, a good liquid-solid separation effect, a granular sludge sedimentation, high reaction activity, simultaneous nitrification and denitrification, light membrane pollution, and long service life. It can be used for water reuse in communities and buildings, hospital wastewater treatment, fecal wastewater treatment, advanced treatment of various high-concentration organic industrial wastewater, landfill / compost leachate treatment, and micro-polluted drinking water purification. Background technique [0002] Since the reform and opening up, my country's economy has achieve...
