通过水泥厂粉尘污染的监测和实地调查表明:水泥厂粉尘粒径小于2微米的占61.0%,小于5微米占92.9%,可见尘粒小,分散度高,对人群健康危害性大,灰尘自然沉降量夏秋高于冬春,均以立窑点含量(分别为240.4550吨/平方公里·月和227.0514吨/平方公里·月)最高,其次是窑尾点(分别为214.5139吨/平方公里·月和153.4192吨/平方公里·月).大气 TSP(总悬浮微粒)一次最高浓度与日平均最高浓度均越过国家大气环境二级标准.一日时点变化以8时和18时浓度最高,13时最低;空间分布仍以立窑点浓度最高.调查发现,该地区人群中上呼吸道疾病占67.5%,其余为眼疾、慢性鼻炎,慢性咽喉炎、中耳炎、肺功能低下等疾患,表明该厂粉尘已危害人群健康,故发展水泥生产的同时,应千方百计防止环境污染.
Through the cement factory dust pollution monitoring and field surveys show that: cement plant dust particle size less than 2 microns accounted for 61.0%, less than 5 microns accounted for 92.9%, showing small dust particles, high dispersion, harmful to human health, dust and natural The amount of settlement was higher in summer and autumn than in winter and spring, with the maximum content of shaft kiln (240.4550 t / km 2 and 227.0514 t / km 2, respectively), followed by the kiln tails (214.5139 t / And 153.4192 tons per square kilometer per month respectively.) The maximum concentration of air TSP (total aerosols) and the daily average maximum concentration both surpassed the national atmospheric environment Class II standard, and the change of the first day was the highest at 8:00 and 18:00. At 13:00 The lowest, the spatial distribution is still the highest concentration of shaft kiln.Study found that 67.5% of the population in the upper respiratory tract diseases, the rest of the eye disease, chronic rhinitis, chronic pharyngitis, otitis media, pulmonary dysfunction and other diseases that the plant has been dust Endanger people’s health, so the development of cement production at the same time, should do everything possible to prevent environmental pollution.
