Water quality health risk assessment and counter-measure for drinking water source;

Distribution of algae and the establishment of prediction model of cyanophyta cell density in some surface water source of Zhengzhou;

Analysis of water source from the collapse column of Changcun coalmine;

Feasibility of the permenent water resource in Fenxiao mine area;

Application of integer planning in optimal allocation of drinking water resources in the rural area;

Based on hydrochemical data of water samples from each water-bearing stratum, a discernment model of mine shaft water resource outburst is established using fuzzy comprehensive evaluation.

Three causes are found,that is,the water resources,the passages and the power.

Analyses the make-up of the ground water resources system ,in the same time ,points out the importance of exploiting the ground water resources, studies the water quality, the water quantity, the water pressure of the surface water of collapse zone.

The average amount of water resources apiece inTianjin is 160m3 , which is one fifteenth of our country .

The inhibition of low light intensity on the growth of Microcystis aeruginosa in raw water;

The influence extent and reason of suspended solid (SS) on polluted raw water bio pretreatment operation were studied in this article.

In this paper is introduced the principle of biological contact oxidation technology (BCOT) to treat polluted raw water.

Analysis on water quality purifying effect in biofilm formation and start process of Dongshen source water biological pretreatment project;

Pilot test was made on the improvement of source water quality in Meiliang Bay through the use of enriched microbes in Taihu Lake by artificial media.

The method of HPLC was applied to examine exactly the contents of trace intracellular and extracellular LR, YR, RR microcystin in source water and treated water, of which the samples were collected from August 1998 to June 1999 and concentrated by ODS silica gel column.
