Description
Technical field
The present invention relates to ship sewage treatment technical field, particularly a kind for the treatment of unit of catalytic oxidation Sewage from Ships and method.
Background technology
Along with developing on an unprecedented scale of seafaring and ocean exploitation; the phenomenon of the sea pollution that the random discharge of Sewage from Ships causes is of common occurrence; the destruction that ocean environment suffers is more and more serious, and under the overall background of global call protection of the environment, the mankind also strengthen increasingly to the protection consciousness of ocean environment.Meanwhile, Sewage from Ships is equivalent to a kind of mobility source of pollution, and what its random discharge became the increase along with ships quantity to the impact of ocean, Water Environment in Urban Rivers and lake, reservoir can not be ignored.
The external research for Sewage from Ships treatment process and technology, approximately to start from phase late 1960s, be some some countries that stipulate that add the earliest the anti-pollution Regulation G reatT.GreaT.GT of MARPOL73/78 supplemental provisions Vl < < Sewage from Ships >, mainly Shi Yi America and Japan are representative.More conventional treatment process mainly contains biological process (activated sludge process, biomembrance process, membrane biological process), physico-chemical process (coagulating sedimentation, filtration etc.), electrochemical process etc.
Adopting boat domestic sewage treatment device that biological process is technique the most representative is the German instrument manufacturing company limited Bio mono-ComPact series of producing and " super trident machine " serial marine sewage treatment system of Britain HAMWORTHY company production.As activated sludge process, it is the widespread use of a kind of energy and effective traditional sewage treatment process, it is a sewage disposal technology with very big development prospect, it has the extensive adaptability to water quality and the water yield, there is flexile operation scheme, controlled good, can reach nitrogen, phosphorus are had to certain removal effect by the setting of anaerobism or oxygen-starved area simultaneously.Its ultimate principle is: under the condition of oxygenation, utilize oxygen consumption bacteria microorganism to carry out oxygenolysis to organism, then carry out solid-liquid separation by settling tank.Its advantage is that organism is removed to rate is high, but owing to being subject to underway the waving of hull usually to cause settling tank sedimentation effect not obvious, causes water outlet muddy.
Biomembrance process is to utilize catalytic oxidation technology to reach the processing to Sewage from Ships, it is a class waste water aerobic biologic treating technique arranged side by side with activated sludge process, utilization is attached on structures biofilm medium, and can grow thereon, breed, by cell outside the born of the same parents that stretch in extracellular polymer microbial cell is formed there is fibrous tangled structure (as the filler using) in contact oxidation technology.Adopt biomembrance process can make sludge yield large, activity is good (as is converted to MLSS, can reach 13g/L), there is Biofilm characteristics, can there is not sludge bulking phenomenon, strong to load impact ability, adopt biomembrance process can greatly reduce the volume of aeration tank, take up an area less, but the little meeting of volumetric loading makes processing efficiency not high.It is not cheap that film is vulnerable to contamination and plugging, damage, price, is not suitable for the use in the larger situation of sewage quantity.
Adopt the boat domestic sewage treatment device that physico-chemical process is technique, mainly to circulate, pulverize, precipitate by chemical agent is added in sewage, discharge after carrying out disinfection again, the advantage of this method is that treatment process is simple, device volume is little, shortcoming is not carry out biochemical reaction, to organic matter removal, will be not thorough, and need to consume a large amount of sterilizing agents, operate miscellaneous.
Adopting the Typical Representative of the boat domestic sewage treatment device that electrolytic process is technique is the Omnipure equipment series of the severn Trent De Nora company of the U.S., and electrolysis ratio juris is: by electrochemical process, sewage is oxidized, is sterilized.It is the sewage that is mixed with seawater to be sent into electrolyzer carry out electrolysis, produces NaClO as oxygenant and sterilizing agent, and under the effect of NaClO, organism in sewage is oxidized to be fallen, and bacterium is killed, to reach the object of sewage purification.The advantage of using electrolytic process is that can to reach device little, and treatment scheme is fast, but its Operation and Maintenance is complicated, and working cost is also high, and after processing, the colourity effect of water outlet is poor.
In conjunction with above-mentioned analysis, the problems such as prior art has complex structure or working cost is high, inconvenient operation, and treatment effect is not up to standard need to solve.
