Background
The history of the sewage treatment industry in China starts in 1921, and the development is rapidly achieved in the last two decades of reform opening, but the history still lags behind the requirement of urban development. It is counted that 427 municipal sewage treatment plants, of which 282 secondary treatment plants were established in the country by the end of 2000. The construction of the sewage treatment plants greatly improves the treatment level of urban sewage, but the increase of the treatment capacity is still far lagged behind the increase of the sewage discharge amount, the actual situation of the sewage treatment industry in China is that the sewage treatment rate is low, and drainage pipe networks of a plurality of old urban areas even cannot be systematized.
The slow increase of the urban sewage treatment capacity and the low sewage treatment rate are main reasons for water environment pollution in China, so that the water environment is continuously deteriorated, and the development of economy and society in China is severely restricted. The main reasons for the slow increase of the urban sewage treatment capacity in China can be summarized as follows: the sewage treatment technology falls behind: the urban sewage treatment technology is the key to whether the urban sewage treatment facility can be operated efficiently, and the current development situation shows that the sewage treatment technology and equipment suitable for the actual national conditions of China are lacked in the aspect of sewage treatment of small and medium-sized cities. Therefore, it is imperative to explore and develop sewage treatment technologies for medium and small cities (towns) suitable for the national conditions of China and master a batch of treatment technologies and urban sewage treatment technologies for representative pollution sources in the medium and small cities (towns).
The flocculation tank (commonly called reaction tank) for completing the flocculation process plays an important role in water purification treatment. The particle sizes of suspended substances and limb substances in natural water are very small. To remove these substances, coagulation is usually used, that is, a proper coagulant is added to raw water, and the mixture is thoroughly mixed to make the colloidal stability be deteriorated (destabilized) and adsorbed with the polymer phase after the coagulant is introduced into the water, so that the particles have flocculation property. The purpose of the flocculation basin is to create suitable hydraulic conditions for the particles with flocculation properties to aggregate in mutual contact to form larger flocks. Therefore, whether the design of the flocculation tank is correct or not is related to the flocculation effect, and the flocculation effect directly influences the precipitation effect of subsequent treatment.
The in-process of flocculation can use agitating unit, and the effect of flocculation stirring is the colloidal particle that makes the aquatic bump, adsorbs and knot into the sail flower of a certain size gradually, tries most sail flowers to hold back in the sedimentation tank, but current agitating unit structure is complicated, and manufacturing cost is on the high side, and the simplification of agitator moreover for final effect greatly reduced also of flocculating. In view of this, the inventor designs a flocculation tank stirring device in the wastewater treatment process, the medium stirred in the stirrer of the stirring device is wastewater, and the wastewater treatment process uses a motor as a driving device, and the wastewater treatment process uses a reducer coupling to drive a straight blade to rotate so as to flocculate colloid particles into larger particles, so that the precipitation is facilitated, and the requirement of water quality purification in the water treatment is met.

K-ratio of Water to speed of the stirrer
A-area of single blade, unit m2
ΣRpThe vector sum of the inner and outer paddles, in m
n-stirrer rotational speed, unit r/min
The speed of rotation in first gear is therefore:
the same principle is that: a second gear: g2＝45s-1、K2＝0.28
By the formula:
obtaining: n is2＝5.9r/min
Third gear: g3＝20s-1，K3＝0.32，
By the formula:
