Water purifying agent for storing Yellow River pumping water and collected rainwater in cellar

Abstract

The invention discloses a water purifying agent for storing Yellow River pumping water and collected rainwater in a cellar. The water purifying agent is prepared from 30-70 parts of flocculating agent, 25-85 parts of sterilization and disinfection agent and 30-40 parts of adsorbent. According to the water purifying agent, components of the water purifying agent and the weight ratio of all the components are preferably selected through a large quantity of experiments; an experimental result shows that each component proportion is scientific and reasonable; flocculation, sediment, sterilization and disinfection and adsorption can be simultaneously carried out on the Yellow River pumping water and the collected rainwater by using the he water purifying agent, so that suspension matters, bacteria, organic pesticide residues, heavy metal and the like can be effectively removed; a try result shows that the water purifying agent has a very good treating effect on pollutants in the water; after the water is treated, the water is clean and the mouth feel is good; after the water is detected, a national domestic drinking water standard can be met; and the water purifying agent is convenient to operate and easy to popularize and implement and has important meanings on guaranteeing the drinking water safety of the masses of national irrigated areas of Yellow River and drought mountain areas.

Description

[0001] technical field [0002] The invention relates to a water purifying agent, in particular to a non-toxic water purifying agent capable of realizing flocculation, precipitation, sterilization and adsorption to quickly purify water sources, and belongs to the technical field of drinking water treatment in vast rural areas in my country. Background technique [0003] Yellow River water pumping irrigation area mainly refers to the area irrigated by water from the Yellow River. In my country's Gansu, Ningxia, Qinghai, Shanxi, Shandong and other provinces, almost all drinking water sources in irrigation areas come from the Yellow River. Due to the relatively scattered rural settlements, it is difficult to implement centralized water treatment. Local townships, village governments, schools and farmers all use the Yellow River The water is directly stored in the water cellar as daily drinking water. Due to the high turbidity and serious pollution of the Yellow River water, aft...

AI Technical Summary

Problems solved by technology

[0005] The current water purifiers are mainly used for secondary treatment of tap water. Due to the high turbidity of the Yellow River water for filling cellar water and the collection of rainwater for cellar water, it is too The water treatment capacity of the micro-filtration water purifier is too small, and it is easy to block

Reverse osmosis micro water treatment, unusable due to no pressure in the water cellar, and the cost is too high

The water purifier is mainly supplied to large and medium-sized water treatment plants. For the water treatment of only 20-100m3 water cellars, it has multiple functions of flocculation, sedimentation, sterilization, decolorization, and removal of organic matter and heavy metals. agent has not been reported
