Description
Technical field
The invention belongs to environmental technology field, relate to a kind of method and specific equipment thereof of handling oil field waste, specifically, this equipment is the semicoke biological fluidized-bed reactor.
Background technology
Along with the develop rapidly of modern industry and the raising of people's living standard, oil increases severely as its demand of main energy sources.Oil development and related industries are also brought very big threat to environment when providing energy basis for national economy.In oilfield development process, oil well produced liquid produces a large amount of oily(waste)waters after the dehydration petroleum transferring station of oil-gas gathering and transportation system carries out oily water separation, and its oil-contg height and complicated component are very serious to the pollution of environment.Be protection environment and maintenance sustainable economic development, countries in the world have given very big concern to the improvement of oil field waste.In view of adopting the conventional physical chemical process to be difficult to realize standard wastewater discharge, developed country since late 1970s the exploration of oil extraction waste water biological treating, China starts to walk a little later in this respect.At present obtained certain progress technically both at home and abroad, the treatment process of being researched and developed mainly contains activated sludge process, biomembrance process, stabilization pond method etc.Biomembrance process influences advantages such as little, that load is high, sludge yield is few because of having the salinity of being subjected to, and has been subjected to the extensive concern in oil field, various countries, studies more have blodisc, bio-contact oxidation, biological fluidized bed etc.Wherein biological fluidized bed is a kind of novel treatment technology of U.S. Ecolotrol company in the exploitation of the year seventies in last century, it uses the very big particle of specific surface area as carrier, waste water makes carrier be in fluidized state with upflow velocity faster, biological concentration and mass-transfer efficiency are all very high, are a kind of biological treatments efficiently.
Carrier in the biological fluidized bed provides the place of growth and breeding for microorganism, and its physicochemical property have material impact to the performance and the efficient of reactor, so the selection of carrier is extremely important.Theoretically, the excellent carrier that is used for biological fluidized bed should possess following characteristic: easy fluidisation, and free settling has absorption property and water absorbing properties preferably; Particle diameter is little, and specific surface area is big, and the space distributes, the shape subglobular of trying one's best; Mechanical property and chemical stability will be got well, and low price.The carrier that can be used for biological fluidized bed at present has gac, zeolite, haydite, quartz sand, granulated glass sphere, coke, organic polymer bead and some complex carriers etc., wherein gac possesses above-mentioned most of feature because of it, with the obvious advantage during as the biological fluidized bed carrier, thereby become one of biological fluidized bed carrier of greatest concern.Small-scale engineering verification has been carried out to the feasibility of granular carbon organism fluidization bed process (GAC-FBR) in recent years in U.S. part oil field, and the result shows that this technology has very high efficient, and water outlet reaches the wastewater discharge standard of offshore oil field strictness fully.Yet, because the gac price is very high, making its in recent years deep purifyings that are used for water more, the application in wastewater treatment is still not extensive.
China is maximum in the world coal production and country of consumption, and the principal mode of present domestic coal utilization is direct burning, and this causes the coal utilization inefficiency, and environmental pollution is serious.For this reason, country widelys popularize clean coal technology since the nineties in 20th century, is core with the gasification engineering again wherein.Semicoke claims blue charcoal again, is the solid product that the bituminous coal etc. of mud coal, brown coal and high volatile obtains after the low temperature pyrogenation gasification.In areas such as China Shaanxi, Inner Mongol, Shanxi, along with the enforcement of gasification engineering, a large amount of semicoke byproducts produce thereupon, and the approach that rationally utilizes at present is very limited, not only causes the wasting of resources, and contaminate environment.Therefore, the approach that utilizes again of developing semicoke has crucial meaning.Semicoke has and the similarly abundant pore texture of gac, can realize and the similar function of gac as the biological fluidized bed carrier after the direct or activated modification; Only be 600～1000 yuan and the semicoke market value is per ton, far below gac; Can directly be used as fuel after losing efficacy as carrier, and needn't consider the regeneration link of complexity, use simply relatively, and reach the purpose of the treatment of wastes with processes of wastes against one another, for the comprehensive utilization of semicoke provides a new way as gac.
Summary of the invention
The defective and the deficiency of cost an arm and a leg when gac is as the biological fluidized bed carrier in the prior art in order to overcome, processing cost is too high solve the problems of the technologies described above, and the invention provides a kind of method and specific equipment thereof of handling oil field waste.
