The invention discloses an oil-containing underground water treatment device and a control method. Impurities, oil dirt and residual agents in water can be effectively removed, and domestic water which accords with the national standard is obtained. The treatment device comprises a coagulative precipitation tank, a walnut shell filter, a water purification filter and dosing equipment. According to the oil-containing underground water treatment device and the control method provided by the invention, the oil dirt in the underground water can be effectively removed, most of impurities in the water can be filtered, the standard of domestic water for residents is reached, uninterrupted water supply can be realized even if in the backwashing process, cleaning and pollution discharge can be automatically performed, the reliability is high, and the application range is wide.
Description
technical field [0001] The invention belongs to the technical field of water treatment in oil field areas, and in particular relates to a water purification device for oily groundwater and a control method for the device. Background technique [0002] Groundwater is an important water resource in inland areas. Because the underground soil and sand have a good filtering effect, groundwater itself is a renewable resource. However, groundwater renewal and self-purification are very slow and often cannot keep up with local water use. Demand, with the standardized and strict requirements of drinking water standards, it is necessary to carry out scientific and standardized water purification treatment on groundwater in order to obtain qualified water quality suitable for residents' lives. [0003] The groundwater produced near the oil field is usually mixed with a lot of oil pollution, and because a large amount of oily sewage will be discharged near the oil field, some chemic...
