Abstract

The invention relates to an organic waste water treatment technology, in particular to a micro-aerated biological filter. According to the technical proposal provided by the invention, the micro-aerated biological filter comprises a first filter and a second filter, which is characterized in that: the first filter is thereon provided with a sewage import pipe and is internally provided with a filter chamber which is vertically provided with a plurality of bamboo tubes which are parallel to each other, the bottom end of each bamboo tube is communicated with the bottom of the first filter, and the top end of each bamboo tube is communicated with an overflow tank of the first filter; the second filter is internally provided with a biological bed which can be moved out or moved in, a massive filter material is placed in the biological bed, the second filter below the biological bed is internally provided with an aeration head, and the second filter above the biological bed is internally provided with a drain pipe; the second filter is internally provided with a flow guiding chamber which guides waste water to the bottom of the biological bed, and the flow guiding chamber is communicated with the overflow tank. The invention shortens biological reaction time, reduces equipment investment and simplifies operation process.

Description

technical field [0001] The invention relates to a technology for treating organic waste water, in particular to a micro-aerated biological filter. Background technique [0002] Schematic diagram of micro-aerated biological filter technology treatment process: waste water tank → water pump → micro-aerated biological filter → micro-aeration → biodegradation → backwash pump → effluent reuse or discharge. [0003] Mechanism of hydrolysis process of micro-aerated biological filter: The biochemical treatment method in the sewage treatment process is the main method to treat organic wastewater. The hydrolysis process is one of the newly developed processes. It refers to the complex The decomposition of organic matter into simpler compounds. Among them, the catalytic reaction efficiency of the enzyme is 106-1013 times higher than that of the non-enzyme reaction, and the above reaction is carried out under the condition of anoxic. The difference between hydrolysis process and anaer...
