Description
Technical field
The present invention relates to Industrial Solid Waste processing technology field, specially a kind of oily sludge goes water-coal-slurry harmless treatment
Method.
Background technology
Oily sludge is a kind of suspension emulsion body, is in thick, and viscosity is larger and is difficult to settle, and property is sufficiently stable,
Have the characteristics that yield is big, oil content is high and intractability is big.Oil exploitation, transport, refining and oily waste water treatment factory
A large amount of oily sludges are generated, discharges, the soil, water body and air of surrounding can be polluted, oil-containing if without being effectively treated
Also contain the poisonous and harmful substances such as a large amount of pathogens and heavy metal in sludge, there is prodigious harm to human health.Containing greasy dirt
Mud belongs to《National Hazard waste register》In specific hazardous waste, China's clear stipulaties must not carry out arbitrary discharge and therefore contain
Greasy dirt becomes a great problem of puzzlement oil refining industry.
Certain Petrochemical Enterprises generates a large amount of oily sludges when handling oily wastewater, and yield is about 3t/d, and solid content is about 20%,
Oil content 10%-15% easily occurs corruption and generates stench.In oily sludge containing a large amount of oil emulsions, can oil slick and dissolved oil,
The combustion heat can burn in 1200-1500kcal/kg, but burning facility investment and operating cost are higher, and single oil-containing
The burning utilization rate of sludge is very low.
The conventional treatment method of oily sludge is outer committee's processing after desiccation, and expense is about 2000 yuan/ton, is not only made to enterprise
At certain financial burden, and with the raising of environmental requirement, the processing requirement of dangerous waste is stringenter, can further limitation look forward to
The development of industry.
A kind of patent " microbial treatment method of oily sludge " (application number：201610519397.4) propose a kind of oil-containing
The microbial treatment method of sludge addition microorganism renovation agent and is uniformly mixed in oily sludge, and watering is turned over until containing greasy dirt
Mud reaches discharge standard, and patent directly carries out petroleum substance using the indigenous microorganism in sludge biodegradable but time-consuming
Longer and treatment effect is unstable." utilizing the experimental study of oily sludge production oil coke slurry " (magnifies pine, oil gas field environment is protected
Shield, 2010,20 (2):18-20) thinner is utilized to reduce the viscosity of oily sludge, water-coal-slurry is directly mixed with coal dust, it is real
The harmless treatment of existing oily sludge, but oily sludge can increase the viscosity of water-coal-slurry to a certain extent.
Water-coal-slurry have good mobility and stability, its main feature is that high combustion efficiency, low stain, economize on coal and environmental protection
Deng.Solid waste with certain calorific value can be with slurry in water-coal-slurry, by water-coal-slurry high-temp combustion realize it is innoxious and
Recycling treatment.
