Chemical industry in three wastes
Posted: Mon Jan 24, 2011 7:08 pm
Now the era of rapid industrial growth of times, with the development of industry, will bring on the pollution also nots allow to ignore, such as chemical industry pollution, but we also take some corresponding effective protective measures referred to as the "three wastes";
1. Waste gas processing produce a small number of toxic gases experiment should be in in the fume hood exhaust equipment, through a gas platoon to arrive outdoor air, be diluted to generate a lot of toxic gases experiment must have absorbed or processing equipment. As of nitrogen oxide, sulfur dioxide etc acidic gas with lye absorption.
2. Wastewater treatment 1, the laboratory shall be equipped with storage residual liquid container, experiments of environmental pollution is produced from residual liquid shall be classified into and designated container storage. 2, acid, alkali liquid according to its chemical properties, separately neutralization post-processing. Make PH reached in 6 ~ 9 between after discharge.
3. Waste destroyed 1, able to natural degradation toxic waste, concentration is buried deep processing. 2 insoluble waste chemicals into the wastewater pipeline ban, must concentrate to incinerators incineration or chemically treated to No harmful. 3, broken glass and other have edge sharpness waste, can't throw into the wastepaper basket inside, to collect in special waste bins processing.
