Endocrine Disrupting

For low-temperature conditions, the municipal sewage plant on the low removal efficiency of endocrine disrupting chemicals, We are the investigation of endocrine disrupting chemicals in a sewage plant of Changchun City. The results showed that the water contains contaminants 2,4,6-Tris[Bis(Methoxymethyl)Amino]-1,3,5-Triazine, the substance is endocrine disruptors chemicals, it is more harmful to the environment. In addition, Out of the water contains Triethylphosphate, it is the metabolites of organ phosphorus pesticides, it also has a greater impact on the environment, they should be targeted pollutants, focusing on removal of sewage under low temperature conditions for the effective removal of EDCs to provide theoretical guidance.

Endocrine Disrupting

The occurrence of emerging contaminants such as endocrine disrupting chemicals (EDCs) in our water resources is of prime concern. With this context, fate and seasonal variation of six EDCs (testosterone, T; progesterone, P; diethyl phthalate, DEP; dibutyl phthalate, DBP; propyl-paraben, PP and butyl-paraben, BP) were assessed throughout the year, i.e. in rainy, winter, spring and summer seasons in the raw, treated wastewater and activated sludge in an activated sludge process (ASP) based sewage treatment plant (STP) located in Haridwar, India. Qualitative and quantitative measurements were performed by gas chromatography-mass spectrometry (GC-MS) analysis. Results indicate that in summer, the examined STP could effectively remove 82.9% of T, 86.4% of P, 95.5% of DEP, 92.4% of DBP, 91.5% of PP, and 89.9% of BP from the wastewater. Among the EDCs considered, higher removal efficiencies were achieved for phthalates in the summer season. GC-MS analysis showed that a small fraction of EDCs was sorbed on the solid fraction of activated sludge. Scanning electron microscopy, energy dispersive X-ray spectroscopy and Fourier transformation infrared spectroscopy analysis were also performed to investigate the occurrence of EDCs in biomass samples. Results of this study also demonstrated that removal efficiency, assessed in terms of physicochemical and microbiological parameters, was maximum in summer and reached minimum in rainy season.

Municipal Sewage Treatment Plant

In this investigation it was found that the waste sludge obtained from a municipal sewage treatment plant could be reclaimed as an adsorbent for removal of organic vapours, i.e. toluene, methyl-ethyl-ketone and 1-1-2-trichloroethylene, through use of a pyrolysis technique. In order to find the optimum manufacturing process, several tests were performed under various conditions in which the addition of a catalyst, temperature control, and residence time in the furnace, were considered as the three major factors. Both the reclaimed adsorbent and commercially available activated carbon were evaluated to determine their adsorption capacity at various influent concentrations of organic vapours.
