It was found that when the treatment of wastewater containing anionic surfactants (LAC) was under the optimal conditions, i.e., electrodes interval of 2cm, treating voltage 8V, and the retention time of 40min,the removal rate of LAS, COD and TOC was over 94.5% ,66.2%,58.7% respectively.
While the BP neural network model after a dynamic training, it had a more precise prediction on the papermaking effluent treatment process with the average relative error of 1.9%, which indicates that the dynamic training BP neural network is greatly superior to the one without dynamic training.
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).
Development and application of some renovated technologies for municipal wastewater treatment in China
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.
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.
Consultants' meeting of IAEA on technical and economic evaluation of the radiation treatment of wastewater
Thus, a hyperthermophilic archaeon was for the first time detected in a system of anaerobic biological treatment of wastewater.
Procedure for treatment of wastewater with a coagulant (aluminum sulfate) and anionic flocculants to remove fats and proteins was studied The purification efficiency was evaluated from the flocculation parameters.
Sodium alginate and chitosan were tested in treatment of wastewater from the flotation processing of hydrobiontics.
