This technology is suitable for treating tank bottom sludge, landing sludge, refining "three sludge" and high-concentration petroleum hydrocarbons organically contaminated soil produced during oil extraction and refining.
After being treated by green parental deoiling and cleaning technology, the oil content can reach less than 2%. After being treated by microbial advanced treatment technology, the oil content of the cleaned sludge meets the requirements of the "Standards for the Control of Pollution in Agricultural Sludge"(GB4284-2018). The mineral oil content of agricultural land is less than 0.3%, and it can even reach the Class A agricultural land standard of less than 0.05%.
</section></section></section></section>(1) Basic principles
The green amphiphilic deoiling and cleaning technology starts from the physical and chemical properties of sludge to build a resource process system with oil, water and solid separation as the main framework. The core of this technology,"Green Biparental Deoiled Cleaning Agent", is a non-toxic, harmless, safe and degradable product. The raw materials mainly come from plants, combined with Zhihe's exclusive series of additives, at appropriate cleaning temperatures, through supporting professional equipment separates the three phases of oil, water and solid. The oil can be recycled as resources, water can be recycled in the system, and the solid phase can be deeply processed by microorganisms.
Microbial advanced treatment technology is a microbial treatment technology used to further reduce the oil content of sludge after the green amphiphilic degreasing agent cleaning technology. The introduction of green amphiphilic degreasing agent can reduce the surface tension of sludge molecules, increase the contact area between sludge and microorganisms, enhance the oxidation-reduction reaction between the two, and achieve further rapid reduction of oil content.
(2) Technical advantages
(1) Investment advantages:In view of the factors such as scattered oily sludge storage sites, small storage scale in single sites, and risks to the environment caused by oily sludge transportation, our company's professional sludge equipment adopts a skid-mounted design for easy transportation. The site only needs to be connected to water and electricity. It can be put into operation. Compared with building a station, the investment in infrastructure and transportation investment is greatly reduced.
(2) Operating expenses:The operating cost of this technology is mainly electricity and chemicals. The comprehensive cost of sludge treatment is between 650- 1,800 yuan/ton. The cost is affected by factors such as the scale of the sludge to be treated, the nature of the sludge (oil content, solid content, garbage content, etc.), and on-site construction environment., treatment target value and other factors.
(3) Operational stability:This technology is highly adaptable to the environment and runs stably.

1. The equipment is skid-mounted design, has strong adaptability to the field environment, and is convenient to transport and use;
2. It has wide technical applicability and can be used to treat various types of sludge and petroleum hydrocarbon organically contaminated soil, and has no requirements for the oil content of raw materials;
3. Waste oil in sludge can be recycled as resources, and the recovery rate can reach more than 90%;
4. The water during the treatment process can be recycled. After the system water is saturated, it can enter the water treatment system and be discharged after meeting relevant sewage discharge standards;
5. The oil content in the solid phase can be treated to a minimum of 0.5‰, which can actually be formulated according to relevant standards and owner requirements;
6. The chemicals used in this technology are green and environmentally friendly and will not cause secondary pollution to the environment.
(2) Condition requirements
1. The processing capacity of a single set of equipment is 1-15m3/h, and the actual processing capacity will fluctuate depending on the raw material conditions;
2. The site is flat and can be connected to electricity and water that meet the requirements;
3. Depending on the nature of raw materials, a pretreatment system needs to be equipped.
(3) Typical scale
The typical processing capacity of this technology is 1m3/h, 15m3/h.

The equipment included in this technology is skid-mounted design and includes: stirring system, screening system, centrifugal system, dosing system and biological advanced treatment system.
(2) Operation management
Based on the composition of the sludge and the small-scale test data in the laboratory, the operating parameters of the system and the amount of reagent added are determined. The production and operation process has a high degree of automation and low labor costs.
</section></section></section></section>1. Investment situation
The main equipment can be invested by our company, and the owner's investment can be ignored.
(2) Operating expenses
Operating expenses mainly include: chemicals, electricity, water, steam, labor, etc. The equivalent cost per ton of sludge treatment is 650-1800 yuan.
(3) Benefit analysis
1. Economic benefit analysis
(1) For areas with relevant sludge disposal standards, this technology can reduce the oil content of sludge to meet the requirements of relevant standards, saving the cost of enterprise delivery and disposal. In some areas, the cost of sludge delivery and disposal is 3500 yuan/ton;
(2) For areas where there are no relevant sludge disposal standards, sludge can be reduced to reduce delivery costs;
(3) The recycled waste oil can be utilized as resources. For example, sludge with an oil content of 10%, the value of each ton of recoverable oil is about 200 yuan.
2. Environmental benefit analysis
Oily sludge belongs to hazardous waste, its number is HW08, which is very harmful to the environment. This technology can minimize the concentration of pollutants in oil-containing sludge or petroleum hydrocarbon organically contaminated soil, reduce the harm of sludge or contaminated soil to the environment and humans in production and waste enterprises, transportation processes and temporary storage sites, and improve work and The living environment has a positive effect on the environment.
