A combined process, demulsification-Fenton oxidation-coagulation, has been employed to treat a sort of high-strength and stable emulsion wastewater produced from a machinery factory. The influences of demulsifier species, dosage of Fenton reagents, oxidation reaction time and pH of coagulation have been investigated. The results indicate that AlCl3 is the most effective demulsifier and the optimal...
The pilot plant study comprised the sequencing batch reactor (SBR) operational mode of a contact oxidation filtration separation integrated bioreactor (CFBR) for treating municipal wastewater. The CFBR was made up of an upper biofilm reactor and a lower gravitational filtration bed. Polyacrylonitrile balls (50mm diameter, 237 m2/m3 specific surface, 90% porosity, and 50.2% packing rate) were filled...
Starch wastewater has high turbidity and COD, heavy odor after anaerobic processing. Discharging this kind of sewage could cause serious environmental pollution, and therefore it need to be treated and reached the national standard before discharge. This experiment based on the specific characteristics of starch wastewater. The process was designed as follows: after anaerobic hydrolysis prior to degradation...
A new process of enhanced dissolved air floatation (DAF) by pulsed high voltage discharge was studied in this paper. With high voltage discharges, removal rate of some normal water quality indexes were better improved, such as UV254 and CODMn from 0.145 to 0.142 and from 6.2 mg/L to 5.8 mg/L. The turbidity of water after treated with pulsed high voltage discharges was larger than that without discharges...
The orthogonal test was used to study the bactericidal capability of potassium ferrate and its influencing factors for bacteria and Escherichia coli when potassium ferrate is playing coagulation effect in treating micro-polluted water. The results showed that the order of the primary and secondary factors affecting the germicidal efficacy of potassium ferrate was oxidation time, reagent amount and...
An experiment of a reformative MBR process that a combined process of "biological contact oxidation and micro- filtration (MF) membrane" was conducted for the treatment of aquatic products processing wastewater. The experiment results showed that the combined process for waste water the reduction rates of the CODCr reached 95%, and NH4-N was in the range of 40~50%. HRT played an important...
