Abstract

The invention discloses a novel environment-friendly water treatment agent, and relates to the technical field of a water treatment agent. The novel environment-friendly water treatment agent is prepared from the following raw materials in parts by weight: 15 to 22 parts of tannin, 8 to 17 parts of polyaspartic acid, 18 to 25 parts of polyaluminum sulfate, 10 to 16 parts of lime cream, 8 to 14 parts of chitin, 8 to 14 parts of seaweed glue, 5 to 12 parts of arabic gum, 9 to 12 parts of sodium hypochlorite, 5 to 10 parts of active carbon and 6 to 12 parts of quartz sand. The water treatment agent contains various ingredients; impurities in the sewage can be effectively treated; the influence of the sewage on the living environment of people can be reduced; no toxic substance is contained; green and environment-friendly effects are achieved; the preparation process is simple; the cost is low; the effect is good.

Description

technical field [0001] The invention relates to the field of water treatment agents, in particular to a novel environment-friendly water treatment agent and a preparation method thereof. Background technique [0002] The human demand for water resources is expanding at an alarming rate, and at the same time, the increasingly serious water pollution is eroding a large amount of water resources available for consumption. Human beings all over the world are paying attention to environmental protection and environmental governance. Water pollution is also one of the environmental problems that people consider, because it seriously threatens human daily life and their own health. About 200 tons of garbage are dumped into rivers, lakes and streams around the world every day, and all rivers that flow through cities are polluted. [0003] With the continuous improvement of people's living standards, human water consumption is also increasing, and domestic sewage is also increasing....
