Abstract

The invention provides a mercury-containing wastewater treatment method and a mercury-containing wastewater treatment device. The device comprises an oil-water-mercury separator and a gas main, wherein the gas main is connected with the bottom of a gaseous mercury adsorber, and the gas main is respectively connected with the top of the oil-water-mercury separator, an air-floated mercury removal apparatus and a mercury adsorption-filtration apparatus by pipelines; and the side wall of the oil-water-mercury separator, the side wall of the air-floated mercury removal apparatus and the top of the mercury adsorption-filtration apparatus are sequentially connected by pipelines, and the bottom of the mercury adsorption-filtration apparatus is connected with the upper part of the side wall of a purified water tank by a purified water pipeline. The method comprises the following steps that after being treated by the oil-water-mercury separator, the air-floated mercury removal apparatus, the mercury adsorption-filtration apparatus and the gaseous mercury adsorber, mercury-containing wastewater enters the purified water tank by the purified water pipeline, and exhaust gas discharged from the oil-water-mercury separator, the air-floated mercury removal apparatus and the mercury adsorption-filtration apparatus enters the gaseous mercury adsorber to carry out adsorption treatment. The method and device provided by embodiments of the invention carry out targeted treatment on mercury-containing wastewater occurring in oil and gas exploration, and the mercury content of treated mercury-containing wastewater is less than 10 ppb.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method and device for treating mercury-containing sewage. Background technique [0002] China is a water-scarce country, and sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to use urban sewage and industrial sewage for non-drinking purposes such as greening, flushing, and replenishment of ornamental water bodies after being treated by membrane bioreactors and other equipment, while using clean water for drinking and other high-quality water-required purposes. Urban sewage and industrial sewage are available nearby, which can avoid long-distance water transportation and realize the full utilization of water resources through nearby treatment. pollute groundwater sources. Sewage reuse has been widely used in many water-scarce areas in the world, and it is considered the most practical technology for sewage treatment in th...
