“…With this target, over the past few years techniques have been introduced in an attempt to heavy metal removal and P recovery from sewage sludge, sludge ash or digester supernatant, including thermal treatments [6,7], bioleaching methods [8,9], chemical extraction [10,11] and electrodialytic methods [12,13]. These projects are economically not feasible due to their complex processes for phosphorus recovery.…”

“…Among diverse wastes, sewage sludge is a potential source for adsorbents due to its huge annual production from municipal wastewater treatment plants. However, raw sewage sludge is water swelling and generally contains various pollutants [12, 13]. Therefore, appropriate treatment is necessary to make this common solid waste to be a stable and safe adsorbent.…”

A novel approach was employed to load α-Fe 2 O 3 and α-FeOOH onto sewage sludge biochar (SBC) with the purpose of efficient nickel (Ni) removal. A high Ni(II) adsorption capacity of 35.50 mg·g -1 in 100 ppm Ni(II) solution with 10 mg modified sewage sludge biochar (MSBC) was achieved. The adsorption kinetic and isotherm were fitted well by the pseudo-second-order model and the Langmuir model, respectively. The optimal pH was found around a neutral pH of 7. The adsorption mechanisms of Ni(II) onto MSBC were described as the synergistic effects of electrostatic attraction, ion exchange, inner-sphere complexation and co-precipitation. The initial rapid adsorption phenomenon could be attributed to electrostatic attraction and ion exchange, and then inner-sphere complexation and co-precipitation acted as a crucial role in the following step. The remarkable performance of MSBC provides an effective waste utilization approach to simultaneous sewage sludge recycle and Ni removal from aqueous solution.

“…The key is to select indicators that can represent different industries. Compared with organic pollutants and pathogens, heavy metals are ubiquitous in industrial sewage sludge, and they cannot be degraded under natural conditions (Dai et al, 2019;Marchenko et al, 2018;Xu et al, 2017). Common treatment methods, e.g.…”

The illegal disposal of industrial sewage sludge has caused serious environmental pollution. To develop identi cation techniques of industrial sewage sludge based on the characteristic ngerprints carried by sewage sludge itself is a promising method that is helpful to clarify the responsibility of illegal enterprises. In this study, heavy metal composition and speciation of sewage sludge from industries (including printing and dyeing industry and other industries) and municipal sewage treatment plant located in eastern China were determined and their performance of classi cation was evaluated by principal component analysis (PCA) and linear discrimination analysis (LDA). Results showed that heavy metal composition and speciation can be an effective tool for distinguishing sewage sludge between printing and dyeing industry and other industries, with an accuracy rate of 82.9% and 100%, respectively. Antimony (Sb) and zinc (Zn) are two characteristic heavy metals, which can be used to identity sewage sludge in printing and dyeing sub-industries with an accuracy rate of 90%. The combination of these three methods may be a precise and promising tool for identi cation of sewage sludge between industries and sub-industries. This study developed a potential method for tracing the industrial sources of sewage sludge and establishing the identi cation database of industrial sewage sludge, and provided technical support for the government to supervise the illegal dumping and disposal of industrial sewage sludge.
