Abstract
Although rainwater collection can alleviate water shortages in seasonally water-deficient area, the water’s sanitary condition is usually very poor. By 4 factors 3 levels orthogonal experiment, this paper studied the coupling effects of temperature, nutrient, suspended solids and total phosphorus on the bacteria content of storage water, and analyzed their variance and regression. The mechanism of how environmental factors affected storage water’s quality were explored, and a binary first-order linear correlation equation of bacterial content with temperature and nutrients was established. The research results can provide reference for the safe utilization of storage water in water-deficient area.
