Abstract

The invention discloses corrosion and scale inhibition biodegradable bactericide used for water treatment. The bactericide is prepared from 5-30% of hexadecyl dimethyl (2-sulphurous) ethyl ammonium, 5-20% of acrylic acid-allyloxy polyether-acrylate copolymers, 5-30% of polyquaternium, 2-25% of polyaspartic acid and 25-50% of water. The 28-day degradation rate of the bactericide reaches 90%, and the bactericide has a good bactericidal effect on microorganism soil bacteria, sulfate reducting bacteria, iron bacteria and heterotrophic bacteria, has the corrosion and scale inhibition functions, has a good dispersion effect on calcium carbonate scale and is environment-friendly bactericide used for water treatment.

Description

technical field [0001] The invention relates to the technical field of water treatment agents, in particular to a biodegradable bactericide for water treatment with scale and corrosion inhibition. Background technique [0002] With the rapid growth of my country's economy, the shortage of water resources has become one of the important factors restricting my country's economic development. my country's industrial water consumption accounts for one-fifth of the national water consumption, but the reuse rate of industrial water is far lower than that of developed countries. Among them, industrial circulation cooling water is a large part of industrial water, so new water treatment methods are developed and researched. Products and processes, improving the reuse rate of industrial circulating water is crucial to alleviating and solving the contradiction between water shortage and waste of water resources. [0003] In addition, the chlorine-containing oxidizing fungicides in the...
