For adapting to the requirement of current emissions standard, also intrinsic for solving traditional biological dephosphorization and denitrification process contradiction,
Research worker proposes Denitrifying Phosphorus Removal Technology.I.e. refer to utilize Denitrifying Phosphate Accumulating Organisms under anoxic conditions, with nitre
Hydrochlorate is electron acceptor, synchronously completes denitrification (denitrogenation) and excess is taken the photograph at the one of phosphorus (dephosphorization) process
Reason technology.Compared with traditional biological denitrification dephosphorization technique, it is avoided or weakens above-mentioned standard biologic denitrogenation and removes
Contradiction common in phosphorus, can also make oxygen amount and sludge yield decline 30% and 50% respectively simultaneously, and subtract
Run complexity less.The present invention is theoretical for the anaerobic-aerobic-anoxia SBR work according to research with denitrification dephosphorization
Skill, is divided into the operational mode of anaerobic-aerobic-anoxia by the cycle of operation of SBR technique.This synchronous denitrification dephosphorizing
Technique has the advantage that and 1. uses single sludge system, and more double sludge systems can save energy resource consumption with anti-
Answer the occupation of land of device；2. aerobic section is set in the middle of, for the denitrifying phosphorus removal technique that relatively anaerobic-anoxic mode is run,
Sludge activity is high and is difficult to aging；3. aerobic section nitrobacteria can produce the nitrate nitrogen supply anoxia section of abundance
Denitrification phosphorus-collecting, for more traditional dephosphorization process, eliminates the nitrate nitrogen impact on poly-phosphorus reaction.
From the point of view for the treatment of effect according to the sewage treatment unit having been supplied on boats and ships, biological treatment is because of ship
Oceangoing ship rocks, jolting causes sedimentation effect bad, and effluent quality is not good enough.The present invention enters after biological treatment again
Row membrance separation, the most both ensure that effluent quality, turn avoid the frequent jams of membrane module.
BOD, SS of Sewage from Ships are much higher compared with city domestic sewage, again because of on boats and ships number few,
Load variations is obvious, and load impact is big.The present invention uses SBR technique, and in addition with pretreatment, is greatly reduced
The impact that impact load brings, treatment effect is stable, compare with other sewage-treatment plants and have great advantage.
SBR active sludge treatment process has just shown since coming out that floor space is little, anti impulsion load, process
The advantages such as effect stability, limit yet with automatization level at that time and fail to be used widely.The present invention
Can use computer that water pump, agitator and aerator etc. are realized Automated condtrol, it is not necessary to professional manages
Reason, and the sanitary sewage disposal on applicable boats and ships.
The present invention is by combining denitrification nitrogen and phosphorus removal biological treatment with membrane separation technique, and arranges
Water inlet macerator pump, cyclone sand settling device in addition pretreatment, Sewage from Ships will be had one preferable the most stable
Treatment effect, each index of water outlet all can be stably under discharge standard, and simple in construction, and equipment is less,
Easy to maintenance, operate automatization, be very suitable for Sewage from Ships and process.
