Method for preparing compound water purifying agent for emergency treatment of water pollution of drinking water source

Abstract

The invention discloses a method for preparing a compound water purifying agent for emergency treatment of water pollution of a drinking water source, which comprises the following steps of: grinding concave soil raw ore into fine powder, and sieving by using a sieve with 100 to 300 meshes to obtain concave soil powder; calcining the concave soil powder at the temperature of between 350 and 500 DEG C for 1 to 5 hours, or radiating the concave soil powder by using microwaves with the power of 300 to 600W for 5 to 15 minutes to obtain modified concave soil; and mixing the modified concave soil and an inorganic polymer coagulant accounting for 5 to10 weight percent of the modified concave soil and potassium permanganate accounting for 1 to 5 weight percent of the modified concave soil in aqueous solution, stirring for uniform dispersion, drying, and grinding to obtain the water purifying agent finished product. The compound water purifying agent can obviously reduce the content of organic matters, algae toxins, heavy metals and the like in the water of the polluted drinking water source, the manufacturing cost is low, the operating process is simple, the sedimentation velocity is high, the sludge volume is small, the residues of inorganic reagents are a few, and the compound water purifying agent has chemical and biological safety and is a novel environment-friendly and high-efficiency water purifying agent for emergency treatment of the water pollution of the drinking water source.

Description

technical field [0001] The invention relates to the technical field of water supply treatment, in particular to a method for preparing a composite water purifier for emergency treatment of drinking water source water pollution. Background technique [0002] With the obvious acceleration of industrialization and urbanization in our country, the water quality of the river network has seriously exceeded the standard, and sudden water pollution incidents have occurred from time to time, such as phenol pollution in water source water, algae blooms, and heavy metal pollution. At the same time, problems such as unsafe drinking water in rural areas have also emerged. More and more, in some areas, it has not only become a bottleneck restricting the sustainable development of economy and society, but also an important factor affecting the health of residents. Therefore, water quality emergency treatment and safety measures need to be improved urgently. To solve the problem of drinkin...
