Equipped with control cabinet, the control cabinet is electrically connected with the elevator pump, the blowdown valve.
7. a kind of sewage simultaneous phosphorus and nitrogen removal method, it is characterised in that: the following steps are included:
Sewage lifting to Anaerobic Contact oxidation pond is carried out anaerobic hydrolysis-acidification reaction by step 1；
Step 2, the water promotion that will be reacted in Anaerobic Contact oxidation pond by anaerobic hydrolysis-acidification carry out aerobic anti-to trickling biofilter
It answers；
Step 3, by trickling biofilter pass through aerobic reaction water a part flow back into Anaerobic Contact oxidation pond carry out denitrification take off
Nitrogen processing, another part flow into sedimentation basin and are settled；
Step 4, by the water promotion by sedimentation basin sedimentation, to filtering, dephosphorization tank is filtered and dephosphorization is handled；
Step 5, by filtering and dephosphorization, treated that water enters obtains clean water after sterilization pool carries out sterilizing.
8. sewage simultaneous phosphorus and nitrogen removal method according to claim 7, it is characterised in that: in step 3, trickling biofilter reflux
Water to Anaerobic Contact oxidation pond is twice of the water of inflow sedimentation basin.
9. sewage simultaneous phosphorus and nitrogen removal method according to claim 7, it is characterised in that: further include that centre mentions in step 4
Pond is risen, the intermediate pond that promoted is first flowed by the water that settling tank settles and concentrates, then be thus lifted to the filtering dephosphorization tank.
10. sewage simultaneous phosphorus and nitrogen removal method according to claim 7, it is characterised in that: in steps of 5, the sterilization disappears
Poison includes one of chlorine tablets sterilization, ultraviolet sterilization or several combinations.
