Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Join shown in Fig. 1 and Fig. 2, present embodiments provides a kind of extremely frigid zones treatment method for rural sewage, including pretreatment
Workshop section, biochemical treatment workshop section, advanced treating workshop section and Treatment of Sludge workshop section.
Pretreatment workshop section: sewage collects into grille well 1, intercepts biggish floating material and suspended matter in water using grid,
Then enter conditioning tank 2, be homogenized after water quality and water and hydrolysis acidification pool 3 is promoted to by conditioning tank elevator pump 21.Sewage in it into
Macromolecular difficult to degrade is decomposed into the small organic molecule being readily biodegradable by row hydrolysis acidification.Hydrolysis acidification pool water outlet is certainly
Stream enters contact-oxidation pool 4.Each pollutants removal rate of this workshop section is respectively CODcr:10%, SS:45%.
Biochemical treatment workshop section: contact-oxidation pool 4 provides air by blower 41, big using adhering on high-performance bio filler
Microorganism is measured to completely remove the organic matter in sewage.It, which is discharged, enters secondary settling tank 5, carries out mud-water separation；Processed sewage
