In a rapid stirrer that stirs sludge and a flocculant in a tank with a stirring blade, the rotation speed of the stirring blade is increased at a set rate with an increase in the amount of charged sludge, the rotation speed of the stirring blade is reduced at the set rate with a decrease in the amount of charged sludge, and flocculated flocs having a fixed floc diameter are stably generated even when operating conditions change so as to fluctuate the amount of charged sludge.

A separation device with two-stage gas-liquid mixture and conical spiral fields is provided. A first-stage uniform mixer performs first-stage gas-liquid crushing and uniform mixing process by an outer micropore ceramic pipe, a middle micropore ceramic pipe and an inner micropore ceramic pipe and crushes large bubbles in the gas-liquid two-phase flow into small bubbles. A second-stage uniform mixer performs second-stage gas-liquid crushing and uniform mixing process. A whirlpool-making gas collector adjusts the gas-liquid uniform mixing flow obtained after two-stage gas-liquid uniform mixing into hollow-core type high-speed two-phase spiral flow. A conical degasser performs gas-liquid efficient separation operation in a high-speed conical spiral field. A two-stage uniform mixing control system and a gas-liquid separation control system automatically regulate and control the flow and the flow pressure of the gas-liquid two-phase flow, the gas-liquid uniform mixing flow and degassed gas flow and degassed liquid flow.
