Excess sludge is a typical byproduct of biological treatment tanks in wastewater treatment plant (WWTP), which not only contains high water content and has large volume, but also contains large amount of pollutants, such as pathogenic microorganism, heavy metals, organics and antibiotic resistance genes (ARG). Without effective treatment and disposal, excess sludge can be a significant environmental threat encountered by the municipal wastewater treatment industry in China. The treatment and disposal of sludge by conventional technologies can be expensive, accounting for up to 50%-60% of the cost of WWTP operation. Moreover, at current developing stage of our country, the phenomenon of "paying more attention to water but less attention to sludge" often occurs in WWTP. Thus, the sludge reduction faced with a serious task. The development of high-performance sludge dewatering processes has become a major area of research in China. . This project focused on the serious pollution problem of excess sludge in our country, proposed a novel research topic on the dielectric relaxation and moisture transformation of heterogeneous biosolids matrix during the E-peroxone-Fe(III) complex conditioning and dewatering process for it. The following contents will be studied: developing the E-peroxone-Fe(III) complex conditioning technology for excessive sludge; studying the dielectric relaxation dynamics and moisture transformation characteristics of heterogeneous biosolids matrix along the whole E-peroxone-Fe(III) complex conditioning and dewatering process with dielectric spectroscopy; revealing the process mechanisms for E-peroxone-Fe(III) complex conditioning and dewatering. Through the implement of this project, not only will a novel E-peroxone-Fe(III) complex conditioning technology be invented, but also the application of dielectric spectroscopy measurement technology will be extended to the sludge conditioning and dewatering fields: monitoring the dynamics of moisture transformation and transport in sludge, raising the auto-control principals, strategy and models for the conditioning reagents dosage or the strength of conditioning ways, revealing the dynamic characteristics and scientific connotation of dielectric relaxation during sludge conditioning and dewatering process. The results of this project will have an important scientific significance and applicable value for promoting the development of sludge conditioning technology, expand the research techniques, reveal the process mechanisms in sludge conditioning and dewatering fields and lay a solid scientific foundation for sludge treatment and disposal process.
