Technical field, realize road tank car cleaning station cycling utilization of wastewater and " zero-emission " target.
Background technology
Road tank car is to contain the important tool with transporting oil, extensively should be had in the major petrochemical refining base in China
With because the fast development road tank car quantity and capacity of highway construction are also increasing and expanded year by year.One large-scale petrochemical
Base averagely possesses tank car quantity for more than 6000, and cleaning 10 times every year of average each car, each 50 tons of water consumption, whole year will disappear
Consume 3,000,000 tons of water.About 3 yuan/ton of industrial water, is recycled after processing, and conserve water 9,000,000 yuan/year, is had very big
Economic benefit.Secondly, the raising recently as whole society's environmental consciousness and the upgrading to environmental protection standard requirement, items pollution are controlled
Reason measure dynamics is increasing, and the pollution problem of oil truck causes the extensive concern of environmental worker.Oil truck the material that changes the outfit,
Produced first in periodic cleaning and maintenance process substantial amounts of sewage, particularly tank car fill oil types difference cause sewage into
Point complexity, sewage oil content often more than 500mg/L, while may containing the toxicity such as sulfide, benzene, volatile phenol and lead tetraethide compared with
Big pollutant, cause the serious pollution of surrounding enviroment.
Processing for oily waste water, frequently with " oil removal-coagulation/air supporting-biochemistry " old three sets of handling process.But due to oil
Tank car with water is high-temperature water or high-temperature steam when cleaning, and leaving water temperature is still very high after cleaning, and 55 DEG C of average out to, rinse water is too high
Temperature be unfavorable for biochemical treatment.Secondly, after HIGH TEMPERATURE PURGE water is directly discharged into oil interceptor, oil removal effect is reduced, deepens the breast of oil
Change degree, so as to increase subsequent biochemical processing organic loading.So generally oil truck cleaning station can be set before oil interceptor it is slow
Pond is rushed, to reduce temperature, but this can cause substantial amounts of waste heat to be wasted, unfavorable in saving, while can also produce atmosphere pollution.Cause
This, oil truck rinse water water quality has particularity so that conventional coagulation and biochemical process treatment effeciency is low, it is difficult to meets that it reaches
Mark the requirement of discharge.Again, it is big to clean tank car water requirement, according to current environmentally friendly development situation, it is laggard that water process is cleaned to tank car
Row reuse is the developing direction of this wastewater processing technology.

Very big, combustion process will also result in atmosphere pollution when coal is fuel.And this can then be made up as fuel by producing methane by the use of anaerobism
A little defects.Anaerobic device and processing system are entered for all kinds of sewage caused by oil truck cleaning station and with water feature, this patent
Row particular design, oil truck rinse water waste heat effectively is utilized, significantly reduce emulsification degree oily in waste water, improve oil removal effect
Rate about more than 15%, anaerobic reactor biogas output and quality are improved by adding septic tank wastewater, biogas steams as boiler for producing
Vapour（Or hot water）The energy, while utilize steam（Or hot water）Harmless processing is carried out to septic tank wastewater, result in formation of material
With the closed cycle of energy flow, oil truck cleaning station energy consumption, material consumption are farthest reduced, saves operating cost more than 30%,
Water outlet reaches railway quality of reused water standard after processing（TB 3007-2000）, finally realize oil truck cleaning station circulation warp
Ji and the target of " zero-emission ".
