Hengyang industrial waste _ _ rich students FIG industrial wastewater treatment project

Industrial waste detection sampling equipment: According to the characteristics to be collected in the industrial wastewater to determine the nature and analysis of project wastewater, prepare the appropriate flow measurement instruments and equipment, according to each analysis item sampling equipment required to prepare complete, require field testing and stationary items to prepare the instruments and reagents, should effectively pay attention to safety during transport equipment and reagents. Industrial Waste Water at the scene: the sampling officer may enter the factory, to fully understand the production process of raw materials and products, capacity utilization, industrial use of water, industrial wastewater discharge law and so on. Because of the test site bear relatively complete enterprise, widely distributed, although some large enterprises, but small businesses are more workshops, obsolete equipment, poor management, coupled with environmental awareness talk thin, individual enterprises to avoid detection Ming, both underground drain, therefore, the discharge of industrial waste water from the water must check links, tracking and tracing, until ascertain the whereabouts of sewage. Guangzhou-Dongguan People's Hospital Medical students Environmental Wastewater Image: Industrial Wastewater treatment of wastewater containing cyanide technology in industrial production, gold and silver wet extraction, chemical fiber production, coking, ammonia, electroplating, gas production and other industries have to use cyanide or a cyanide byproduct, the production process is bound to emit a certain amount of wastewater containing cyanide. Activated carbon is used to purify waste water has a long history, used in treatment of wastewater containing cyanide reported in the literature is also increasing. Treatment of wastewater containing methanol can be activated carbon adsorption of methanol, but not strong adsorption capacity, low methanol content only suitable for wastewater treatment. Engineering operation results show that activated carbon for treatment of low water content A drunk can be a mixture of COD from 40mg / L down to 12mg / L or less, and for methanol removal rate of 93.16% to 100% after treatment can meet back boiler water desalination system water quality requirements. Phenol Waste phenol-containing wastewater from a wide range of petrochemical plants, resin plants, coking plants and oil refinery plants. Experimental results show: good adsorption performance of activated carbon for phenol, but temperature is not conducive to absorption, adsorption capacity will decrease, but elevated temperatures can shorten the time to reach adsorption equilibrium. Activated carbon is used to dealing with wastewater, the presence of an amount and adsorption time best value in acidic and neutral conditions, the removal rate changed little, but under strong alkaline conditions, the phenol removal sharp decline, the more strongly alkaline adsorption effects worse.
