Integrated MABR apparatus used for black and odorous water treatment, and treatment method thereof

Abstract

The invention discloses an integrated MABR apparatus used for black and odorous water treatment, and a treatment method thereof. The apparatus adopts MABR to substitute an MBR technology, and is combined with an oil separation and sand settlement tank and a phosphate removal filter tank to form a modular unit in order to reach the best black and odorous river treatment effect. The apparatus comprises an upper layer comprehensive treatment unit and a lower layer phosphate removal unit, the upper layer comprehensive treatment unit comprises the oil separation and sand settlement tank and an integrated MABR tank, the oil separation and sand settlement tank is placed in front of the integrated MABR tank, and the oil separation and sand settlement tank is connected with an integrated MABR tank body through a pipeline; the integrated MABR tank comprises a grating chamber, a reaction zone, a settlement zone, a clear water tank and an equipment room; the equipment room is placed at the tops of the settlement zone and the clear water tank; and the lower layer phosphate removal unit comprises the phosphate removal filter tank and a mixed filler layer arranged in the phosphate removal filter tank, and the upper end of the clear water tank is provided with a water outlet which is connected with the bottom of the phosphate removal filter tank through a pipeline.

Description

technical field [0001] The invention relates to a device and a treatment method for treating black and odorous water, in particular to an integrated MABR device and a treatment method for treating black and odorous water. Background technique [0002] As an important part of the urban ecosystem, the river channel has various ecological functions such as providing the aquatic biological environment, beautifying the city, and landscape entertainment. In addition, it also undertakes important functions such as flood control and drainage, adjusting the climate and environment, and absorbing pollutants. It is the city's survival. and the basis for development. With the rapid development of my country's urban economy and the continuous advancement of urbanization and industrialization, the water environment of urban rivers has been seriously polluted and destroyed, and the high content of oxygen-consuming organic pollutants and nitrogen and phosphorus has led to black, odorous and...

Problems solved by technology

This type of method is stable and effective, safe and durable, and consumes less energy. However, its purification effect is affected by various conditions and factors such as water quality, hydrology, and climate. It takes a long time to take effect, requires regular management, and is not suitable for the treatment of heavily polluted rivers

[0007] As a sewage treatment technology emerging in recent years, MBR membrane bioreactor has achieved good results in the restoration of black and odorous rivers. Compared with conventional river restoration technologies, its treatment effect is significantly improved, operation and management are more convenient, and it occupies a smaller area. , but there is serious membrane fouling and clogging, regular dosing and backwashing is required, and because the black and odorous river water contains a lot of surfactants, a large amount of foam will be generated during the process of oxygenation and aeration, accompanied by volatilization Escaping of harmful pollutants, endangering the surrounding environment, large gas lift loss, low oxygen utilization rate, high fan energy consumption, and the lack of denitrification efficiency of a single MBR membrane bioreactor, additional processes need to be added to meet the total nitrogen of the black odorous river. removal request
