Abstract
The invention provides a petrochemical wastewater treatment method and relates to the technical field of the petrochemical industry. The petrochemical wastewater treatment method comprises the following steps: step 1, collecting petrochemical wastewater and precipitating the collected petrochemical wastewater, after precipitating, filtering out floating objects on the surface of the wastewater and then performing reverse osmosis to obtain reverse osmosis concentrated water and reverse osmosis clear water; step 2, performing aerobic microorganism treatment on the reverse osmosis concentrated water obtained in the step 1; step 3, performing aerobic biological treatment on the reverse osmosis clear water obtained in the step 1; step 4, detecting the concentrated water treated in the step 2 and the clear water treated in the step 3, and if the concentrated water and the clear water did not pass the detection, performing secondary treatment; step 5, performing sterilization treatment on the wastewater treated in the step 4, filtering the wastewater by use of a filter and then discharging the treated wastewater. The petrochemical wastewater treatment method is capable of thoroughly and cleanly treating the wastewater and then discharging the treated wastewater, and further is short in operation time and energy-saving.
Description
Technical field
The present invention relates to technical field of petrochemical industry, be specifically related to a kind of petrochemical wastewater treatment process.
Background technology
Petrochemical complex is the important component part of chemical industry, plays an important role in the development of national economy, is one of mainstay industry department of China.Petrochemical complex refers to take oil and natural gas as raw material, produces the processing industry of petroleum products and petrochemicals.Petroleum products, also known as oil product, mainly comprises various oil fuel (gasoline, kerosene, diesel oil etc.) and lubricating oil and liquefied petroleum gas (LPG), oil coke, paraffin, pitch etc.The course of processing of producing these products is often called as refining of petroleum, is called for short oil refining.The further chemical process of stock oil that petrochemicals provide with oil refining process obtains.Producing the first step of petrochemicals is carry out cracking to stock oil gentle (as propane, gasoline, diesel oil etc.), the basic chemical raw materials that to generate with ethene, propylene, divinyl, benzene,toluene,xylene be representative.Second step produces multiple Organic Chemicals (about 200 kinds) and synthetic materials (plastics, synthon, synthetic rubber) with basic chemical raw materials.The production of this two steps product belongs to the scope of petrochemical complex.Organic Chemicals continues the Chemicals that processing can obtain more multi items, does not belong to the scope of petrochemical complex traditionally.In some data, with Sweet natural gas, petroleum naphtha, heavy oil for Material synthesis ammonia, urea, even produce nitric acid and also list petrochemical complex in.
It thoroughly can not process when processing and just be discharged by existing petrochemical wastewater, causes the pollution of environment, contaminate environment while waste resource.
Summary of the invention
The object of this invention is to provide a kind of petrochemical wastewater treatment process, waste water can process clean and discharge by thoroughly, and the operating time is short, saves the energy.
In order to solve the problem existing for background technology, the present invention adopts following technical scheme: its treatment process is:
Step one: petrochemical wastewater is collected, and precipitated, after precipitation, the floating matter of wastewater surface is filtered, then adopt reverse osmosis method to carry out reverse osmosis concentrated water and reverse osmosis clear water;
Step 2: the reverse osmosis concentrated water in step one is carried out aerobic microbiological process;
Step 3: the reverse osmosis clear water in step one is carried out Aerobic biological process;
Step 4: detect the dense water processed in step 2 and step 3 and clear water, when detecting defective, carries out secondary treatment;
Step 5: the waste water processed in step 4 is carried out germicidal treatment, and is discharged by metre filter.
The present invention has following beneficial effect: waste water can be processed thoroughly clean and discharge, and the operating time is short, save the energy.
Embodiment:
This embodiment adopts following technical scheme: its treatment process is:
Step one: petrochemical wastewater is collected, and precipitated, after precipitation, the floating matter of wastewater surface is filtered, then adopt reverse osmosis method to carry out reverse osmosis concentrated water and reverse osmosis clear water;
Step 2: the reverse osmosis concentrated water in step one is carried out aerobic microbiological process;
Step 3: the reverse osmosis clear water in step one is carried out Aerobic biological process;
Step 4: detect the dense water processed in step 2 and step 3 and clear water, when detecting defective, carries out secondary treatment;
Step 5: the waste water processed in step 4 is carried out germicidal treatment, and is discharged by metre filter.
This embodiment has following beneficial effect: waste water can be processed thoroughly clean and discharge, and the operating time is short, save the energy.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
