A PRELIMINARY STUDY ON THE ECOLOGIC DISTRIBUTION OF MICROBES AND MAIN HARMFUL MICROBES IN RECIRCULATING COOLING WATER SYSTEMS OF LUZHOU NATURAL GAS CHEMICAL PLANT

Abstract

Abstract: In wooden cooling tower, the fungi isolated belong to 9 genera: Aspergillus, Penicillium, Trichoderma, Mucor, Cladosporium, Fusarium, Alternaria, Neurospora and Curvularia. And in recirculating cooling water, the heterotropic bacteria belong to Pseudomonas, Micrococcus, Staphylococcus. Bacillus, Sarcina, Xanthomonas and Aerobacter. Among them, Pseudomonas, Xanthomonas and Bacillus are major populations. The ecological distribution of S-reducing bacteria and their errosion effect on metal are also investigated.

Key words: Helicoverpa armigera, Damage, Economic threshold
