Abstract

The invention discloses a biological composite water treatment agent and a preparation method and application thereof. The biological composite water treatment agent consists of 30-40 parts by weightof a compound A agent and 60-70 parts by weight of a compound B agent. First of all, the agent A and agent B are prepared, then the agent A and agent B are mixed evenly and subjected to ultrasonic treatment and low-temperature polymerization reaction to obtain the biological composite water treatment agent, which is applied to sewage treatment, and the treated water quality reaches the sanitary standard of domestic drinking water. The agent A and agent B are not only independent compound water treatment agents, but also raw materials for preparing the biological compound water treatment agents, and can be used singly, jointly or made into the biological compound water treatment agents for sewage treatment. The application method of the biological composite water treatment agent is simple and convenient, the application link does not depend on complicated facilities and equipment for water treatment, and compared with the investment of the current conventional water treatment facilitiesand the dosage of the medicament, the investment of the water treatment equipment can be reduced by more than 80%, the dosage of the sewage treatment medicament can be reduced by 30-50%, and the biological composite water treatment agent is economical, environment-friendly and green and efficient.

Description

technical field [0001] The invention belongs to the field of water treatment and environmental engineering, and in particular relates to a biocomposite water treatment medicament and its preparation method and application. Background technique [0002] The shortage of water resources is a major issue that our country faces that is related to the livelihood of the people in the world, and the control of water pollution is the top priority. my country is one of the countries with serious water shortage and pollution. From the perspective of the national situation, various industries The severe water shortage has caused serious economic losses and social and environmental problems. Water conservation, sewage treatment and development of new water sources are equally important. Vigorously developing water treatment chemicals plays an important role in water conservation and sewage treatment. [0003] Water treatment chemicals are chemical agents that must be used in the process o...
