Technical field
The utility model relates to environmental protection facility field, particularly a kind of platform sewage treatment unit.
Background technology
Since the nineties, membrane bioreactor (MBR) has obtained research widely and application in the state such as Japanese, French, Canadian.Along with perfect, the improvement of film purging method and the raising of sewage effluents water quality requirement of the development of film manufacturing technology, membrane separation process, MBR starts extensively to adopt at sewage treatment industry, is considered to the practical technique of 21 century sewage disposal.
Integrated film bio-reactor is a set of water treating equipment that membrane separation technique and biologic treating technique, intelligent control technology are combined, the flow process that has overcome traditional waste water treatment process is tediously long, floor space is large, the shortcomings such as operational administrative complexity, have stable, compact construction, level of automation is high, the advantages such as attended operation is convenient, and floor space is little, and expense is low.Particularly effluent quality is good, is better than middle water water quality standard.Be suitable for dirty wastewater treatment and the reuse of middle-size and small-size scale.
Referring to Fig. 1, it is the structured flowchart of existing installation.Existing installation comprises successively the fine fack, equalizing tank, anoxic pond, MBR pond, claire, tank of order spread configuration, sludge sump with the adjacent setting in MBR pond.
Shortage of fresh water and the transportation cost of offshore platform are excessive; Set up intermediate water reuse system, adopt the core technology take membrane bioreactor as main body, platform sanitary sewage is processed, reach middle water reuse requirement, flush the toilet and production re-injection for platform living quarters, reduce the fresh water transport throughput rate of platform; Slow down Marine Environmental Pollution, energy-saving and emission-reduction simultaneously.Sanitary sewage is carried out to reuse to greatest extent, avoid overlapping investment.
Realizing in process of the present utility model, contriver finds that prior art at least exists following problem:
1, in the water after existing installation sewage disposal, contained organic pollutants is more, and particularly LAS (cats product, bathing, laundry produce) is not effectively obtained processing direct row sea, can pollute ocean environment;
2, existing installation is to adopting the sewage disposal of seawater toilet-flushing to owe that up to standard (the general saltiness of seawater is 30～35g/L, general aerobic bacterial classification is when in sewage, saltiness is 2～3g/L left and right, its metabolic capacity will be suppressed and cause death, affects effluent quality);
3, existing installation is very micro-to the removal effect of the ammonia nitrogen in sewage and phosphorus, also not good to the removal effect of more complicated organic pollutant.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of platform sewage treatment unit.Described technical scheme is as follows:
The utility model embodiment provides a kind of platform sewage treatment unit, and described platform sewage treatment unit comprises successively the fine fack, equalizing tank, anoxic pond, MBR pond, claire, tank of order spread configuration, sludge sump with the adjacent setting in described MBR pond;
At described equalizing tank front end, add and put doser;
At described tank front-end configuration chlorine dioxide generator.
Particularly, in described doser, add water purification agent.
Particularly, the film in described platform sewage treatment unit uses aperture 0.4 μ m hollow fiber membrane.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
1, this device adopts aerobic, anoxic process in conjunction with platform sewage is all effectively processed, and water outlet fully recovering, has avoided ocean environment to pollute;
2, in use, water is flushed the toilet, and reduces the corrosion to platform pipeline, and assurance equipment is effective, stable;
3, the superfluous water of this device processing is squeezed into platform recycle system, realizes " zero release " target;
4, adopt the novel process of biological degradation, denitrogenation dephosphorizing, membrane separation technique reasonable combination, effectively the non-solubility material in water and macromolecule organic matter are held back and separated, SRB, TGB and FeB are had to higher removal effect simultaneously, water outlet is as clear as crystal, colorless and odorless, meets that reuse is flushed the toilet and the requirement of production re-injection;
5, MBR process using membrane separation technique realizes mud-water separation, makes biochemical system can have higher sludge concentration, makes the higher processing power of sewage disposal and capacity of resisting impact load strong, stable;
6, the technical process that this device adopts is succinct, compact construction;
7, producing water ratio is high, and after processing, water outlet can fully recovering;
8, processing efficiency is high, and effluent quality good stable is processed water outlet SS extremely low, very limpid, and sense organ is good, can be directly as reclaimed water reuse;
The mud mud of the technique that 9, this device adopts can reach 30 days age, can make nitrifier content in biochemistry pool far away higher than common process; Meanwhile, owing to adopting the mud-water separation mode of membrane filtration, the nitrifier that is difficult for precipitation in common process is all trapped within biochemical treatment tank; Due to these two reasons, make novel process there is good nitrification and denitrification ability.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
