A photovoltaic tracking system with special cross section and eccentricity overcoming device, the main beam cross section is a rounded square tubular structure; the eccentricity overcoming device is installed between the common column and the main beam of the photovoltaic tracking system, and comprises a mechanism support, a mechanism body and a mechanism fixing seat which cooperate with each other; the mechanism support is fixed on the main beam, and the mechanism fixing seat is fixed below the common column of the photovoltaic tracking system; the mechanism body comprises a hydraulic cylinder and a cylinder barrel which cooperate with each other, the upper end of the cylinder barrel is hinged on the mechanism support and moves under the drive of the mechanism support on the main beam, the tail end of the hydraulic cylinder is hinged on the mechanism fixing seat and forms relative movement with the cylinder barrel, the limiting structure of the cylinder barrel and the two springs act on the springs respectively to compress the springs and generate a thrust on the mechanism support to overcome the gravity eccentricity of the rotation of the photovoltaic tracking system, the torsional performance of the main beam is improved and the torsional deflection is reduced, the damping effect is achieved, and the rotation eccentricity of the photovoltaic tracking is overcome.

The present invention provides a perchlorate wastewater treatment agent, which consists of a targeted removal agent and a guiding activator. The core components of the targeted removal agent include octyl trimethyl ammonium chloride, trioctyl methyl ammonium chloride, benzyl trimethyl ammonium chloride, decanyl trimethyl ammonium chloride, didecyl dimethyl ammonium chloride, dodecyl trimethyl ammonium bromide, dodecyl bishydroxyethyl methyl ammonium chloride, tetradecyl trimethyl ammonium chloride, etc. The guiding activator includes one or more of polyferric sulfate, polyferric chloride, polyaluminum chloride iron, and polyaluminum silicate iron. The treatment agent of the present invention has simple components, and a large number of perchlorate-philic ionic groups contained therein can fully combine with perchlorate in wastewater, and perchlorate is precipitated from water in the form of precipitation, and then separated and removed, and the one-step removal rate is as high as more than 95%.
