The utility model belongs to
sewage treatment technical field discloses a kind of A2O process
sewage treatment filler
assembly with anti-blocking function, the component includes
treatment pond, fixed rod, filler, fan, the stirring
assembly of providing
inert gas, three-way valve and anti-blocking component, the different import of fan and stirring
assembly's export respectively connect to three-way valve, the export of three-way valve is communicated with anti-blocking component by pipeline. The utility model is switched three-way valve selection gas source: high-pressure air provided using fan drives spray
pipe high-speed rotation, forms strong
water flow scouring clean filler, effectively prevents blockage;
Inert gas provided using stirring assembly drives spray
pipe slowly rotates, realizes mild agitation to anaerobic or anoxic zone
sewage under the premise of not introducing
oxygen. The component one
machine multi-ability, clever structure, solve the technical problem of filler blockage and anaerobic zone
oxygen-free stirring, and strong applicability.
