s1: the sewage to be treated is conveyed into the filter box (1) through the sewage inlet (2), the switch valve (31) is opened, the rotating motor (33) in the draught fan (3) is started, the fan device (32) is driven to work, harmful gas contained in the sewage is sucked into the draught fan (3), and the harmful gas is adsorbed and purified by the activated carbon sheet (35) and the HEPA filter plate (36) and then discharged into the surrounding environment, so that secondary pollution is avoided;
s2: the sewage entering the filter box (1) is subjected to double filtering operation of a primary filter screen (4) and a secondary filter screen (5) to remove larger granular impurities contained in the sewage;
s3: the filtered sewage enters a nozzle (9) along with a guide pipe (7) at the bottom of a groove (6), the sewage is sent into a stirring box (8) along with the injection of the nozzle (9), and an appropriate amount of alkaline neutralizing solvent or acidic neutralizing solvent is added into the sewage respectively through an alkaline solvent water tank (14) or an acidic solvent water tank (15) according to the tested acidity and alkalinity of the sewage in advance to perform neutralization reaction on the sewage;
s4: starting a motor (10), wherein the motor (10) drives a stirring rod (11) containing a stirring blade (12) to rotate, and the stirring operation is carried out on the sewage added with the acidic neutralizing solvent or the alkaline neutralizing solvent, so that the efficiency of the neutralization reaction is improved, and a permanent magnet (16) is used for adsorbing metal in the reaction;
s5: after stirring is finished and standing is carried out for a period of time, the treated wastewater is discharged through a sewage discharge port (17), and the impurities after reaction are discharged through a solid discharge port (18).
