甲醛生态学资料
Data of formaldehyde ecology
1、残留与蓄积:资料记载,工业企业区土壤中吸附的甲醛含量可达180-720mg/kg干土。土壤的污染可导致地下水污染,水中甲醛含量可以比表层土高出10-20倍。
1. Residue and accumulation: according to the data, the content of formaldehyde adsorbed in the soil of industrial enterprise area can reach 180-720mg / kg dry soil. Soil pollution can lead to groundwater pollution, and the formaldehyde content in water can be 10-20 times higher than that in topsoil.
甲醛在环境中颇稳定,当水中甲醛浓度为5mg/L时(20℃),观察结果表明,5天内可以保持恒定。水中甲醛浓度为<20mg/L时,可以被曝气池河北立体车库 消防报警器塑料配件 电缆接地箱 电缆保护接地箱 塑料土工格栅 消弧线圈装置 中经驯化的微生物降解消化。而含量为100mg/L时,能抑制微生物对有机物的氧化。当水中甲醛含量为500mg/L时,生物耗氧过程全部中止,水中微生物被杀死。
Formaldehyde is quite stable in the environment. When the concentration of formaldehyde in water is 5mg / L (20 ℃), the observation results show that it can be kept constant within 5 days. When the formaldehyde concentration in the water is less than 20mg / L, it can be degraded and digested by the domesticated microorganism in the aeration tank. When the content is 100mg / L, it can inhibit the oxidation of organic matter by microorganisms. When the formaldehyde content in the water is 500mg / L, the process of biological oxygen consumption stops completely, and the microorganisms in the water are killed.
