The development of new processes and technologies like aerobic granulation has increased the interest in recent years to cope with disadvantages observed in conventional activated sludge process for wastewater treatment. Due to the increased interest in this topic, the fundamentals and applications of ...
Aerobic treatment is a biological wastewater treatment process that takes place in the presence of oxygen. Aerobic biomass converts organics in the wastewater into carbon dioxide and new biomass. Aerobic treatment technologies can act as stand-alone systems for treating raw wastewater, or can be used...
BWG-204 is added in aerobic biological tank directly. 1st day use BWG-204, the dosage is 0.1% of daily wastewater volume, for example, when daily wastewater treatment volume is 4000m3, the first time to add BWG-204 is 4 tons(if biological water stay time is...
Thus, any improvements in reducing the quantity of sludge by virtue of efficient dewatering are always beneficial to the overall wastewater treatment process. Ultrasonic irradiations can be effective in dewatering of suspensions, such as slurries and sludges. Changes of structure and properties of ...
The internal circulation (IC) anaerobic reactor/aerobic process was used to treat the highly-concentrated organic and biodegradable starch wastewater. The great part of organic pollutants are removed in the IC reactor,which relieves pressure on the subsequent aerobic treatment. The operating results show...
Considering that tannery wastewater contained chrome tanning wastewater,the chrome tanning wastewater was separated and pretreated,and the chrome tanning sludge was recycled in the wastewater treatment project of a tannery in Zhejiang Province.The comprehensive wastewater was pretreated by pre-settling and ...
Evaluation of kinetic parameters for biological CNP removal from a municipal wastewater through batch tests Biological carbon, nitrogen, and phosphorus removal from wastewater has become an established process in wastewater treatment practice. Despite the broad k... A Pala,O Boeluekbas - 《Process Bio...
6) aerobic waste treatment 需氧废物处理补充资料:废水需氧生物处理法 利用需氧微生物(主要是需氧细菌)分解废水中的有机污染物,使废水无害化的一种废水生物处理法。废水的这种处理过程的最终产物是二氧化碳、水、氨、硫酸盐和磷酸盐等,处理彻底时,还可产生硝酸盐,这些都是稳定的无机物。 处理机理 废水同需氧微...
Biological wastewater treatment facilities are designed to emulate the purification process that occurs naturally in rivers, lakes and streams. In the simulated environment, conditions are carefully manipulated to spur the degradation of organic contaminants and stabilize the residual sludge. Whether the tre...
Anaerobic baffled reactor/modified contact oxidation tank/biofilter process was used to treat jean rinsing wastewater.The running results show that the volume loading rates of anaerobic baffled reactor and contact oxidation tank are 1.05 kgCOD/(m3·d) and 0.52 kgCOD/(m3·d) respectively.When the ...
