Abstract

The invention provides a moringa oleifera water purifying agent. The water purifying agent is characterized in that: the water purifying agent is prepared from components of, by mass: 90% to 100% of moringa oleifera extract, and 0 to 10% of a chemical water purifying agent. According to the invention, moringa oleifera oil extraction residuals are adopted; moringa oleifera effective components areextracted; and a complete and comprehensive utilization of moringa oleifera seeds is realized. The moringa oleifera water purifying agent is a pure plant extract. When the moringa oleifera water purifying agent is used for purifying water, no toxicity or harm is brought in. Therefore, harms to human and secondary pollutions to the environment brought by chemical water purifying agents can be solved from the source. The moringa oleifera water purifying agent is suitable for rural water purification. With the water purifying agent, a problem of drinking-water safety of rural population can be solved. The water purifying agent is applied in the purifications of turbid waters such as river water, lake water and rainwater, and brings better purification effects than chemical water purifying agents. The moringa oleifera water purifying agent can be blended with chemical water purifying agents for purifying urban sewage. Therefore, adoption amount of chemical water purifying agents is greatly reduced.

Description

technical field [0001] The invention relates to a water purifying agent, in particular to the preparation and water purifying technology of a Moringa oleifera water purifying agent, and belongs to the technical field of water purifying agent production. Background technique [0002] The purification of drinking water is now a topic of common concern all over the world. In developing countries, the quality of drinking water is often not guaranteed. In developed countries, due to the long-term use of chemical water purifiers, the chemical substances remaining in the water may cause damage to the human body, and the environmental problems caused by the residue after water purification cannot be ignored. Aluminum salt is the most widely used chemical flocculant for water treatment in the world. Its flocculation effect is good, but there are also significant defects at the same time, that is, aluminum ions will remain in the water after aluminum salt treatment, and the residual ...
