The invention relates to a
sewage treatment device for reusing
polyester beverage bottles, which comprises a
chassis and a working platform arranged on the
chassis, wherein, two sides of the work platform are provided with a guardrail, and the working platform is connected with
stairs. The
chassis is provided with a filtering equipment, an end of which is provided with a
settling device beneath, and the other end of the filtering equipment is communicated with
sludge collecting troughs; the
settling device is provided with a transporting screw, an end of which is also connected with the
sludge collecting troughs; the two
sludge collecting troughs are both connected with a sludge presser. The
sewage treatment device flocculates, settles, filters and presses the
sewage generated in a cleaning process to change the sludge into clods; the pressed water is transferred to a filtering screen through a sewage pump for circulation, thus realizing reclaiming and reusing. The
sewage treatment device completely solves a plurality of problems during the reusing process of beverage bottles, decreases the labor intensity, improves work efficiency, reduces work risks, saves water, solves the secondary
pollution problem of sewage and waste residue completely, and meets the requirement of the development of
circular economy.
