The present invention relates to a kind of sewage treatment unit, a kind of specifically electrification of processing Sewage from Ships
System.
Background technology
Ship is also brought to water ecological setting as a kind of important means of transport while creating economic value
Huge challenge.Ship toilet, clinic will usually be come from, the waste water that is excluded and waste at live animal is loaded and become
" Heisui River " i.e. sanitary sewage.
Contain a large amount of microorganism, organic matter and nitrogen phosphorus in Sewage from Ships, frequently enters natural water and have very greatly
Harm：(1) a large amount of sanitary sewages are discharged into water body, and organic matter, which is degraded by microorganisms, leads to oxygen deficit, make marine climate environment by broken
It is bad, force the marine animals such as fish dead or migration.(2) contaminated wastewater degree is very high, if being directly discharged into waters, it will influences water
Self-purification capacity, to change the entire ecological characteristic in waters.(3) after the nutritive salt in sanitary sewage enters water body, plant of swimming
Object undue growth and breeding, body eutrophication lead to wawter bloom and breakout of red tide cycle time.(4) marine flora and animal
The multistage form (such as fish) such as group is replaced by rudimentary form (such as mud worm).(5) meeting such as the bacterium in sewage, pathogen
Cause mankind's parasitics and communicable disease.
For this purpose, the United Nations's International Maritime Organization (IMO) (IMO) passed through MEPC.227 (64) resolutions on October 5th, 2012 in 2016
Resolve instead of MEPC.159 (55), newly increased the emission request of total nitrogen and total phosphorus, limitation be respectively 20 (Qi/Qe) mg/L and
1.0(Qi/Qe)mg/L。
The processing method of Sewage from Ships is broadly divided into bioanalysis and physico-chemical process, and bioanalysis is mainly bio-contact oxidation
Method, activated sludge process, SBR, MBR etc..The advantages such as bioanalysis has high treating effect, simple in structure, and operating cost is low, but have dress
It sets and starts that the time is long, and waving when being not suitable with ship's navigation, the defects of anti-load variations energy force difference.Physico-chemical process mainly has wadding
The solidifying precipitation method, membrane separation process, electrochemical process and filtration method etc., electric flocculation, electro-catalytic oxidation technology wherein in electrochemical method
Using more in terms of ship sewage treatment.It has many advantages, such as small, efficient, but operating cost is higher, and goes
It is ineffective except TN, discharge standard cannot be met.To sum up, previous conventional method is not thorough enough to the processing of sanitary sewage
Bottom is extremely difficult to the discharge standard newly resolved, and needs that previous technique is reformed and optimized.
Electric flocculation technique is to be combined with water pollutant by sacrificial anode to generate cation or hydrated cation
A kind of method of flco is generated, and cathode will produce the gases such as hydrogen, certain air supporting effect can be reached, it is dirty to be directed to life
The removal effect of phosphorus in water is preferable.
Electro-catalysis technology is divided to electrocatalytic oxidation and electro-catalysis to restore two parts, the direct oxygen that electrocatalytic oxidation passes through anode
Organic pollution in the substances indirect oxidation water such as hydroxyl radical free radical, ozone and the Active Chlorine of change and generation；And electro-catalysis is also
Original is to go back protohydrogen by the direct-reduction of cathode and generation come the reducing substances in indirect reduction water, and electro-catalysis reduction is existing
It is usually used in handling the nitrate ion in underground water, but uses conventional electrode materials, since it is to N2Selectivity it is relatively low, lead
Cause treatment effect relatively low.
