Activated carbon was prepared from the sewage sludge of municipal wastewater treatment plant by chemical activation (activation reagent is ZnCl2) and was used for the adsorption of dye (reactive brilliant red K-2BP).
      
Geochemistry characteristics and evaluation of the pollution extent of arsenic in wastewater irrigated soil in the North of Tian
      
The isolation and identification of high efficient biohydrogen production anaerobic bacteria are the important foundations for the fermented biohydrogen production process by anaerobic digesting organic wastewater.
      
Development and application of some renovated technologies for municipal wastewater treatment in China
      
Wastewater discharge, especially municipal wastewater discharge, and non-point pollution sources are becoming the major water pollution source and research focus.
      
Great efforts have been made on water pollution control and a number of renovated technologies and processes for municipal wastewater treatment and reclamation as well as non-point pollution control have been developed and applied in China.
      
Acid resistance of methanogenic bacteria in a two-stage anaerobic process treating high concentration methanol wastewater
      
In this study, the two-stage upflow anaerobic sludge blanket (UASB) system and batch experiments were employed to evaluate the performance of anaerobic digestion for the treatment of high concentration methanol wastewater.
      
Classification of contaminants and treatability evaluation of domestic wastewater
      
Long-term sampling and analysis were conducted in a domestic wastewater treatment plant for the investigation on the characteristics of the representative contaminants in raw sewage such as SS, COD, BOD5, TP, and TN.
      
A treatability evaluation diagram was proposed for a rational selection of wastewater treatment process in accordance with raw water quality.
      
This work aims to explore a procedure to improve biological wastewater treatment efficiency using low intensity ultrasound.
      
The aerobic activated sludge from a municipal wastewater treatment plant was used as the experimental material.
      
Therefore, to improve the wastewater treatment efficiency of bioreactors, ultrasound with an intensity of 0.3 W/cm2 could be employed to irradiate a part of the AS in the bioreactor for 10 min every 8 h.
