HFEEC, the pioneer if China Oil and Gas industry, focusing on oily wastewater treatment and oily sludge treatment, service scope include industrial wastewater treatment, solid waste treatment, soil remediation, and etc., we keep innovating our process and optimizing our technical proposal.
The most severe environmental protection problems in oilfield exploration is the oil produced wastewater treatment for reuse and discharge. In China oilfield such as Daqing, Shengli, Xinjiang, Changqing and etc., The water injection is an effective method to improve oil production rate, but the water injection specification is different to meet and large water demand. The oil produced water content is increasing with the oilfield exploration, so whether the oil produced water can be treated is a constraint factor for China oilfield sustainable development.
Heavy oil wastewater reuse technology
Produced Water to Be Re-injected in Low Permeability Oil Reservoirs
High-salt wastewater reuse technology
Oily wastewater standard discharge process
The wastewater produced by refining and chemical industry contains large amount of oil, sulphur and other toxic matters, the simple process can not meet the process requirement, process combination is more suitable, such as filtration, ultrafiltration, activated carbon adsorption, RO and etc., which can get the water quality to meet the required standard. Treatment of refining and chemical wastewater, the priority is analyze the pollutants, identify the substance characteristic and interconnection, avoid direct and indirect pollutions, make sure comprehensive technical treatment of the water.
Petrochemical wastewater treatment for reuse process
Petrochemical wastewater standard discharge technology
With the developing of urbanization and industrialization, sanitary wastewater pollutions is getting worse and more, how to effectively treat the sanitary wastewater have become an important factor of city and economy development. In China, 674,000,000 people live in the country, 2,500,000 villages, 35,000,000 ton water is discharge, less than 25% water is treated, more than 96% water is place to discharge and treated. The living standard of country has become better, but the basic construction and management have been left behind, sewage pour ground surface ditch and direct emissions, rain sewage mixed flow, random pile up garbage exudate, roadside village runoff pollution is serious, the environmental quality is poor, eutrophication and serious destruction of biodiversity, ecosystem self-purifying ability is weak, has restricted the rural economy the all-round development of the ecological environment, has affected the construction of a harmonious villages, the pace of the harmonious society, also affects the "dream - beautiful countryside in China"
Rural wastewater centralized processing technology

updating....
At present the main soil pollution repair technology are physical repair, chemical remediation, bioremediation, heat treatment technology, stable/curing technology, etc.
It was a high and new tech enterprise and the first batch of university-industry cooperation demonstra -tion base of Liaoning, the key enterprise of Chinese environmental protection industry, and the first ba -tch member unit of Chinese industrial energy sav -ing and cleaner production association.
