Embodiment Construction

[0011] The present invention is further described in conjunction with the following examples:

[0012] (1) Description of water intake point

[0013] The effluent of a reclaimed water plant enters a landscape lake (reclaimed water is the only water source). There are several fountain facilities built in the center of the lake and surrounding water-friendly platforms, which are open irregularly during holidays. A certain amount of water samples were taken at the lakeside, the sampling time was May 12, 2005, and the water temperature at the sampling point was 24.2°C.

[0014] (2) Water sample pretreatment

[0015] The skin sensitivity is low, so the skin irritation test water sample is concentrated, and the concentration method is as follows. Each 500ml water sample was extracted three times with 50ml, 20ml, and 10ml of analytically pure ethyl acetate to increase the recovery rate. Get about 600ml of extract per 9L of water sample. Concentrate after the extraction is complet...

Abstract

This invention discloses one safety evaluation technique by use of recycle water as contact amusement water. The technique uses different concentration times water sample to process test on large ear rabbit skin and eyes through observing tested part reaction evaluation to generate water contact safety.

Description

Technical field: [0001] The invention belongs to the water body safety evaluation technology, in particular to the contact safety evaluation technology of regenerated water. Background technique: [0002] Since reclaimed water may contain a certain amount of organic pollutants, heavy metals and other chemical substances, the environmental and health problems caused by the use of reclaimed water have attracted more and more attention. Some cities have reused recycled water for landscape and entertainment water bodies, such as ornamental lakes, small fountains, waterfalls, etc. People will inevitably have physical contact with water bodies during hydrophilic activities (such as boating and children's water play), and even water will enter the eyes. Whether the various chemical substances in reclaimed water will cause contact hazards to the hydrophilic population, there is currently no such evaluation method and standard in China. The contact safety evaluation technology for ...
