| Zusammenfassung: | A method of using concentrated pretreatment to detect comprehensive toxicity of water body includes sending original water in original water box to Millipore filter by lifting pump, returning outlet water from said filter back to said water box and flowing water being processed cyclically by said filter to intermediate water box, sending water in intermediate water box to reverse osmosis membrance unit being used to process said water cyclically to obtain water sample being concentrated by 10-100 times, determining loss rate of luminous bacteria in concentrated water sample for obtaining comprehensive toxicity comparison of water body under the same condition. |
