The integration of the upflow anaerobic sludge blanket reactor and different posttreatment systems such as constructed wetlands, downflow hanging sponge, and downflow hanging nonwoven fabric reactor.Integrated and Hybrid Process Technology for Water and Wastewater Treatment...
Compared with animal wastewater, municipal wastewater has less nitrogen and phosphorus. However, there are often considerable amounts of heavy metals such as lead, zinc, and copper in raw municipal sewage. The traditional municipal wastewater treatment process includes three stages: primary, secondary,...
In this paper, a feasible municipal wastewater treatment process, using the upflow anaerobic sludge blanket (UASB) or the anaerobic baffled reactor (ABR) as an anaerobic pre-treatment system, and the reed bed or the stabilization pond with supporting media as a post-treatment system, is presented...
The basic control items mainly includes regular pollutants which affect water environment and can be removed out by regular municipal wastewater treatment process, as well as a part level I pollutants ( a total of 19 items). Select control items include pollutants which have a long period time ...
It thus revealed that the ecotoxicity of wastewater increased after treatment by the DAT-IAT process, which demanded more studies to address the regulation of the ecological risk. In particular, the inhibition of wheat root elongation was far more sensitive than the germination of wheat seeds under...
An Experiment was studied on the composite MUCT process used in a municipal wastewater treatment plant in Tianjin,the effects of the said process on nitrogen and phosphorus removal under different SRT conditions were primarily investigated. 采用复合式MUCT工艺在天津某城市污水处理厂进行试验研究,重点考察...
In wastewater treatment, MBR system has obvious advantages compared with other biological treatment methods:1. High remove rate of contamination, stable effluent water quality, and dispense with disinfection;2. Realized the separation of HRT (Hydraulic retention time) and SRT (sludg...
2) municipal sewage treatment plant 城市污水处理厂 1. It is hoped to provide basis for the future research and process design of odor control in other municipal sewage treatment plant. 本文介绍了其工作原理、工艺特点、影响因素以及国内外应用现状及其局限性,希望对于我国其它城市污水处理厂除臭系统的...
An Austrian research project focused on the development of process indicators for treatment with different process and operation modes. The whole treatment... S Lindtner,H Kroiss,O Nowak - 《Water Science & Technology A Journal of the International Association on Water Pollution Research》 被引量:...
Based on the experimental results of the lab-scale reactor and the operational data of the demonstration project, the wastewater treatment plant with one-stage anammox process was comprehensively evaluated and analyzed in this paper. Firstly,the mass balance of the COD and nitrogen was analyzed. The...
