Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of side of milk products waste recycling
Method.
Background technology
Milk products waste is milk powder, fresh milk, modulation milk beverage, fermented yoghourt, yogurt blend, cream, ice cream, snow
The waste water discharged during cake, cheese, lactose, condensed milk and dairy products snack production, waste water is essentially from container and equipment
Rinse water, main component contains product raw material, pH value of waste water 6.5-7.0.Carbohydrate, starch, protein are rich in milk product waste
With aliphatic acid etc., it is a kind of nutritious organic wastewater.
Milk products waste is frequently with materialization treatment process and biological filters such as oil removal, precipitation, coagulation air-float, electrochemistry flocculations
The biochemical processing methods such as pond, catalytic oxidation, aeration tank, oxidation ditch, biological pond are processed.But there is technique in above-mentioned processing method
It is complicated, the shortcomings of processing cost is high, treatment effect is unstable.
If these milk products wastes are directly discharged, the resource of preciousness is not only wasted, and dealt with improperly easily
Putrefactive fermentation, makes water quality black and fouls, and causes serious environmental pollution.
Discarded oil reservoir refers to by not possessing the economic exploitation value after long period of development and stopping noting the oil reservoir for stopping adopting, discard oil reservoir
Recovery percent of reserves it is general higher, more than 40%, residual oil saturation is relatively low, less than 10%.Although such oil reservoir recovery percent of reserves is high,
Residual oil saturation is low, and abundance is low, but because such oil reservoir is large number of, oil in place is still considerable.Therefore, await adopting
The recovery percent of reserves of such oil reservoir is further improved with economically viable technology.
The content of the invention
Turn waste into wealth it is an object of the invention to provide one kind, make full use of the nutriment in milk products waste to carry
The method of the discarded oil reservoir recovery percent of reserves of height, natural gas is converted into by the residual oil in discarded oil reservoir.The method effectively reduces useless
The cost of oil reservoir exploitation is abandoned, the recovery percent of reserves of such oil reservoir is further improved；Simultaneously milk products waste is solved to be processed into
This height and discharge bring the problem of environmental pollution.
A kind of method of milk products waste recycling, it is characterised in that comprise the following steps：
(1) pretreatment of milk products waste

Bacteria concentration is more than 1.0 × 102Individual/ml.
(3) determination of pretreated milk products waste injection rate
As 8%≤SorDuring ﹤ 10%, pretreated milk products waste injection rate is discarded oil reservoir pore volume
0.4~0.6 times；As 5%≤SorDuring ﹤ 8%, pretreated milk products waste injection rate is discarded oil reservoir pore volume
0.2~0.4 times；Work as SorDuring ﹤ 5%, pretreated milk products waste injection rate be discarded oil reservoir pore volume 0.1~
0.2 times.
(4) determination of closing well incubation time
The method that the determination of closing well incubation time uses indoor static culture, the result according to indoor static culture determines to close
Well incubation time.
(5) field test
The pretreated milk products waste of above-mentioned amount is injected from the water injection well of discarded oil reservoir；Closed after the completion of injection
Well culture；Incubation time drives a well gas production after terminating.
Wherein, described acid is hydrochloric acid or acetic acid, and described alkali is NaOH or potassium hydroxide.
The method of described indoor static culture, comprises the following steps that：Choose the High Pressure Model that volume is 800~1000ml
Pipe 1, model pipe is vacuumized；It is then injected into the production fluid 200-300ml of discarded oil reservoir；Secondly the pretreated breast of injection is made
Product industrial wastewater, injection rate is 0.3~0.6 times of discarded oil reservoir production fluid；Heated during model pipe is placed into insulating box, insulating box
Setting temperature be discarded oil reservoir temperature；Model pipe is pressurizeed, the reservoir pressure of discarded oil reservoir is forced into；It is quiet after the completion of pressurization
State culture, each two month takes 1 gaseous sample, until not producing experiment untill methane gas to terminate, from beginning static culture to reality
The time for testing end is the time of closing well culture.
The speed that described pretreated milk products waste injects from the water injection well of discarded oil reservoir be 10~
20m3/h。
The present invention is using the nutriment nitrogen, phosphorus source and the discarded oil reservoir of trace element activation enriched in milk products waste
In methanogen, methanogen by the oil degradation in discarded oil reservoir turn into economic worth methane gas, both solved
Milk products waste processing cost is high and discharges the problem for bringing environmental pollution, realizes again and hides economical and effective to abandoned oil
Exploitation.
The present invention has the following advantages that and beneficial effect compared with prior art：
(1) present invention process is simple, easy to operate, therefore, be conducive to the popularization and application at scene；
(2) present invention is effectively utilized milk products waste, it is to avoid environmental pollution that discharge of wastewater brings and useless
Cost of water treatment problem high；
(3) present invention has the advantages that small investment, low cost, field test results are good.
