step 1: when the water storage tank is used for the first time, the first water inlet valve is opened, the second water inlet valve and the first water outlet valve are closed, and half of the water storage tank starts to store water in the first decay treatment period. The waste water containing radiation sewage flows into the sludge precipitation bin, clear liquid of the intercepted sludge enters the clear liquid bin through a water pipe, the clear liquid gradually flows into the water storage bin, the accumulated clear liquid flows into the plug flow bin, and the clear liquid of the sewage in the plug flow bin is orderly and gradually pushed to the water outlet bin according to the arrangement of the water tank and the water storage edge.

And (3) performing periodic alternate operation successively according to the steps 1 to 3, and finishing the pretreatment of the radiation sewage.
The plug-flow bin can utilize the hydraulic action to enable the water body entering later to gradually push the water body entering first to sequentially advance and flow out, so that when the water body entering later begins to decay, the water body entering first can complete certain decay; the water outlet bin has the functions of natural gravity discharge or mechanical pressure lifting discharge.
When the first water outlet valve or the second water outlet valve is opened, the flow pushing bin starts to discharge water from a water outlet of the flow pushing bin to the water outlet bin, and at the moment, due to the vacuum suction effect of water flow, each sub-bin of the flow pushing bin forms siphon and starts to discharge water from the siphon bell mouth to the water outlet bin.
The utility model can adopt the gravity discharge pipe to naturally discharge the sewage when the embedding depth of the pretreatment tank can meet the gravity natural discharge; when the gravity natural drainage can not be met, a submersible sewage pump can be arranged, and the sewage is drained after being lifted by a pressure drainage pipe.
The effective water storage volume of the integrated tank is the sum of the effective water storage volumes of the sludge precipitation bin, the clear liquid bin, the water storage bin and the plug flow bin; the increase or reduction of effective water storage volume can be flexibly realized through size adjustment of each bin, and the effective water storage volume can be realized only by meeting the requirement of not less than the water discharge in a decay treatment period.
