“…In China, most of the industrial wastewater is pretreated through the sewage treatment plants of factories before being discharged to the centralized wastewater treatment plants (CWWTPs) in industrial parks (Lei et al, 2010). Therefore, such integrated industrial wastewater always exhibits several characteristics, such as complex components, toxicity or inhibition of biological treatment systems, and refractoriness to biodegradation.…”

-A laboratory scale aerobic oxidation ditch combined with an anoxic reactor was conducted to treat wastewater from a chemical industrial park in Tianjin, China. The wastewater exhibited a low biodegradability, and the results of gas chromatography mass spectrometry (GC-MS) analysis showed that some recalcitrant organic components are present in the wastewater. Ammonia nitrogen (NH 4 + -N) removal efficiency of over 90% was obtained. However, the removal efficiencies of total nitrogen (TN) and chemical oxygen demand (COD) were below 16% and 15%, respectively. The addition of glucose to the anoxic reactor in the system increased the removal efficiencies of TN and COD to approximately 72% and 25.57%, respectively. Results of mass balance indicate that about 60% of the external carbon was consumed as electron donor for denitrification, while 40% was consumed as a substrate for co-metabolism. The optimal dose of added glucose was also investigated, which was determined at 0.35 to 1.20 (COD glucose :COD original ).

“…However, the percentage of the volatile phenols discharged by petrochemical wastewater is over 35% (Wu et al, 2015). Many technologies, such as biological processes, advanced oxidation, membrane and adsorption methods, can be used in petrochemical wastewater treatment (Lei et al, 2010). Normally, the cost of physical and chemical technologies is relatively high; therefore, the biological wastewater treatment technology is the most promising treatment process for petrochemical wastewater treatment because of its affordable cost and high efficiency.…”

“…Member industries contributing wastewater to a CETP could be anywhere between the range of 80-500 SSIs per treatment plant. In China, a centralized wastewater treatment (CWWT) facility was demonstrated at a pharmaceutical industrial park that operated at low cost but high efficiency [4]. This concept has also been reported in Malaysia [5], Turkey [6], and Arab region [7], where combined treatment helps in lowering treatment cost, encouraging SSIs to treat their wastewater before releasing it into the environment.…”

A wastewater treatment plant controls the level of pollution reaching the environment. Yet, despite being the most common aerobic route for treatment of wastewater, the activated sludge process is not utilized to its full potential. This is mainly due to the lack of knowledge base correlating the microbial community in the activated sludge to its degradative performance. In this study, the activated biomass at the treatment site was monitored for five consecutive months. Even though operational parameters were kept constant, the microbial community was observed to change after 3 months. This shift was seen to correlate with 25 % loss of degradative efficiency. Target oxygenases were monitored at two time points, and results indicated that the dominating pathway operating in the common effluent treatment plant (CETP) is the degradation of chlorinated aromatics. This study demonstrates the change in degradative efficiency in a CETP with the change in microbial community and analyzes the parameters influencing the microbial community of activated sludge.
