Abstract
The invention discloses a petroleum sewage treatment method. The method is specifically implemented with the following steps: sewage is introduced into a precipitation filtration tank, such that preliminary filtration is carried out, and various solid impurities in the sewage are removed; the treated sewage is introduced into a coarse-graining treatment tank where waste oil contained in the sewage is removed through coarse-graining treatment; a flocculation agent is added into treated sewage; flocs with absorbed waste oil are moved through filtration; wastewater is discharged into a chemical treatment tank; a coagulation agent is added, such that emulsified oil in the oil-containing wastewater is removed; and the treated wastewater is delivered to departments adopting the recycled water through pipes. With the petroleum sewage treatment method provided by the invention, problems of low efficiency and high treatment cost of petroleum sewage treatment methods in prior arts are solved.
Description
Technical field
The invention belongs to sewage water treatment method technical field, relate to a kind of petroleum waste water processing method.
Background technology
Oil field generally all adopts the development scheme of water filling, particularly much has been enter into the oil field of middle and late stage mining phase, and crude oil water content is high, causes oil recovery treatment more difficult. The comparison of ingredients contained in oil extraction-generated waste water is complicated, typically contain crude oil, Organic substance, inorganic salt, salt, microorganism etc., its water temperature, salinity, antibacterial amount are higher, and remaining has many impurity, traditional Technology to be extremely difficult to the requirement that oilfield produced water processes. The dosing of the oil recovery treatment adopted at present is very big, causes that medicament expense increases, considerably increases the cost in oil field, reduce economic benefit, develop efficiently, the task of the sewage-treating agent of low cost extremely urgent.
Summary of the invention
It is an object of the invention to provide a kind of petroleum waste water processing method, solve prior art petroleum waste water processing method efficiency low, the problem that processing cost is high.
The technical solution adopted in the present invention is, a kind of petroleum waste water processing method, specifically implements according to following steps:
Step 1, introduces sedimentation and filtration ditch by sewage, carries out preliminary filtration, thus the various solid impurities removed in sewage.
Step 2, is introduced coarse process pond by the sewage after processing in step 1, is processed by coarse and remove waste oil contained in sewage,
Step 3, to adding flocculant in the sewage after processing in step 2, wherein flocculant is mainly organic polymer flocculant and the big class of inorganic flocculant two. The flocculant thrown in and the mass ratio of sewage are 1:50��100, then pass through and filter the flco removal that will be adsorbed with waste oil;
Step 4, enters chemical treatment pool by the waste water after processing in step 3, gives and wherein add coagulant, thus the oil emulsion removed in oily waste water;
Step 5, is delivered to, by the waste water after processing in step 4, the department that can reuse by pipeline.
The feature of the present invention also resides in,
Wherein, filtering ponds are for being divided into multilamellar, and the diameter of every layer of filtrable impurity is different.
Wherein, the coarse material of use can be mineral-type materials, such as quartz sand or coal grain. Can also be Organic substance, such as lipophile material.
Wherein, the coagulant of use is aluminium salt, polyacrylamide or graft starch.
The invention has the beneficial effects as follows, select and be reasonably scheduled that multiple processing method, in conjunction with using these processing methods, make the process of petroleum waste water more efficiently, not only efficiency is fast at high speed, and its effect removing dirty impurities in water is also fine, the physical method that first use cost is relatively low, then re-uses the method needing to add chemical substance, and such arrangement can effectively reduce the cost processing sewage.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
One petroleum waste water processing method of the present invention, specifically implements according to following steps:
Step 1, introduces sedimentation and filtration ditch by sewage, carries out preliminary filtration, thus the various solid impurities removed in sewage.
Filtering ponds therein are for being divided into multilamellar, and the diameter of every layer of filtrable impurity is different.
Step 2, is introduced coarse process pond by the sewage after processing in step 1, is processed by coarse and remove waste oil contained in sewage, and the coarse material wherein used can be mineral-type materials, such as quartz sand or coal grain. Can also be Organic substance, such as lipophile material.
Step 3, to adding flocculant in the sewage after processing in step 2, wherein flocculant is mainly organic polymer flocculant and the big class of inorganic flocculant two. The flocculant thrown in and the mass ratio of sewage are 1:50��100, and much more especially the consumption of this method use flocculant is less, because in step above, has eliminated the waste oil of part, it is possible to need not flocculant. Then pass through to filter and the flco being adsorbed with waste oil is removed;
Step 4, enters chemical treatment pool by the waste water after processing in step 3, gives and wherein add coagulant, thus the oil emulsion removed in oily waste water; The coagulant used is aluminium salt, polyacrylamide or graft starch.
Step 5, is delivered to, by the waste water after processing in step 4, the department that can reuse by pipeline.
The petroleum waste water processing method of the present invention, select and be reasonably scheduled that multiple processing method, in conjunction with using these processing methods, make the process of petroleum waste water more efficiently, not only efficiency is fast at high speed, and its effect removing dirty impurities in water is also fine, the physical method that first use cost is relatively low, then re-uses the method needing to add chemical substance, and such arrangement can effectively reduce the cost processing sewage.
