饲料工业在我国是一个新兴的工业部门,近年来发展很快。据不完全统计,目前全国已经建成和正在筹建年产3000吨以上的饲料厂有220余家,总生产能力150万吨以上。但是,由于建设饲料厂时,选用的机械设备质量不一,负荷不协调,生产运行时噪声很大。全国已建成的饲料厂产生的噪声几乎都超过我国的《工业企业噪声卫生标准》(试行草案)的规定,高达100分贝(A)左右。噪声已成为饲料工业的一大公害,引起了人们的严重关注。治理饲料厂的噪声危害已成为我国饲料行业的重要任务。
Feed industry in our country is a new industrial sector, developed rapidly in recent years. According to incomplete statistics, at present there are more than 220 feed mills in the country that are already under construction and are planning to build an annual output of over 3,000 tons with a total production capacity of over 1.5 million tons. However, due to the construction of feed mill, the quality of the selected machinery and equipment, the load is not coordinated, the production noise is very large. Almost all of the noise produced by feed mills in the country has surpassed the provisions of the “Noise Standard for Hygiene in Industrial Enterprises” (Provisional Draft) in our country, reaching as high as 100 dB (A). Noise has become a public nuisance in the feed industry, causing serious concern. Managing the noise hazards of feedstuffs has become an important task for feed industry in our country.
