1) Without biomass retention Sequential Batch Reactor (WSBR)
The influences of carbon sources,C/N ratio and adding modes of carbon source on simultaneous nitrification and denitrification(SND) in a sequencing batch reactor(SBR) were investigated while treating low C/N synthetic municipal wastewater.
Two types of mature aerobic granular sludge were cultivated in sequencing batch airlift reactor (SBAR) and sequencing batch reactor (SBR),with conventional flocculent activated sludge as seeding sludge in synthetic domestic wastewater.
3) Sequence Batch Reactor(SBR)
4) without biomass retention
A new process(Without biomass retention Sequential Batch Reactor,WSBR) is proposed in which a SBR is operated without biomass retention in order to fulfill denitrification over nitrite,and then a mathematical kinetic model is established to describe nitrification and denitrification in this process.
An orthogonal program of test runs was conducted to optimize the pretreatment operation(daily aeration time,HRT,phosphate concentration of the feed,and the cycle time) of a SBR with no biomass retention,or WSIP(without biomass retention sequential intentify pretreatment) reactor,to enhance biological treatment of Chongqing Heishizi landfill leachate at low temperatures.
5) membrane sequencing batch reactor
Study on performance characteristics of membrane sequencing batch reactor;
Nitrogen removal performance was investigated using synthetic wastewater as feed without sludge discharge in an anaerobic/aerobic membrane sequencing batch reactor (MSBR) during 300 days operation.
6) sequencing batch reactor
Features and application of anaerobic sequencing batch reactor;
Hydraulic retention time of sequencing batch reactor;
The effects of dissolved oxygen concentration and influent carbon to nitrogen ratio on nitrogen removal performance of a wastewater containing strength ammonia nitrogen were investigated in a sequencing batch reactor.
