Abstract

The invention discloses a membrane-concentrated semi-coke wastewater treatment and regeneration and resource recovery and utilization device, including a filtration concentration unit, a coal tar recovery unit, a phenol separation and recovery unit, an ammonia nitrogen recovery unit, a desulfurization unit, a primary biochemical treatment unit, an electrolytic There are eleven units in total including unit, secondary biochemical unit, advanced wastewater treatment unit, desalination reclaimed water production unit and sludge treatment unit. The invention uses membrane filtration, coal tar recovery, dephenolization, deamination, desulfurization, anaerobic treatment, aerobic treatment, electrolysis, reverse osmosis desalination, sludge treatment and other combined devices to carry out advanced treatment of semi-coke wastewater, and finally realize the The recycling of regenerated water realizes pollution elimination and resource saving, which not only realizes the recycling of resources, but also greatly reduces the treatment cost of semi-coke wastewater.

Description

technical field [0001] The invention belongs to the field of water pollution control of environmental engineering, and more specifically refers to a membrane-concentrated semi-coke wastewater treatment regeneration and resource recycling device. Background technique [0002] Semi-coke, also known as semi-coke and coke powder, is an important raw material for ferroalloy, coal gas, and coal chemical production. It is obtained from raw coal through low-temperature dry distillation (about 650°C). Semi-coke production and gas purification process will produce wastewater, called semi-coke wastewater, which is an industrial wastewater with complex components, high concentration of pollutants, stable properties, poor biodegradability, and extremely difficult to treat. The inorganic pollutants in semi-coke wastewater mainly include sulfide, cyanide, ammonia nitrogen and thiocyanide; the organic pollutants are mainly coal tar substances, and the content of phenolic compounds is very h...
