Problems solved by technology

The chroma of printing and dyeing wastewater is particularly serious, and it is difficult to remove it with general biochemical methods
Colored water will also affect the transmission of sunlight, which is not conducive to the growth of aquatic organisms
When chemical oxidation is used to remove chroma, although the chromophoric group of water-soluble dyes can be destroyed and faded, the influence of its residues still exists

Abstract

The invention discloses a cassava-dreg-based printing and dyeing wastewater treatment agent, which is prepared from the following components in parts by weight: 80 to 120 parts of cassava dreg, 20 to 30 parts of activated carbon, 30 to 50 parts of kaolin, 20 to 30 parts of lime, 1 to 5 parts of barium salt, 10 to 15 parts of silica gel, 20 to 30 parts of polyalumina, 10 to 15 parts of calcium sulfite, 5 to 10 parts of sodium polyacrylate and 1 to 5 parts of 2-sucrose acrylate. The cassava-dreg-based printing and dyeing wastewater treatment agent is wide in pollutant treatment range, low in cost, stable in performance and high in effluent quality, and has good effects and precipitation effects; after the agent is added into sewage, suspended matters are immediately flocculated and rapidly precipitated, the treated sewage can reach a discharge standard, and the agent is high in agglomeration intensity and hydrophobicity.

Description

technical field [0001] The invention relates to a wastewater treatment agent, in particular to a printing and dyeing wastewater treatment agent based on cassava residue. Background technique [0002] The printing and dyeing industry is an industry that consumes a large amount of water in the textile industry, and water is used as a medium to participate in the entire dyeing and finishing process. Printing and dyeing wastewater has a large amount of water, high chroma, and complex components. The wastewater contains dyes, pastes, additives, oils, acids and bases, fiber impurities, and inorganic salts. In the structure of dyes, nitro and amino compounds and copper, chromium, Heavy metal elements such as zinc and arsenic have high biological toxicity and seriously pollute the environment. Printing and dyeing wastewater contains a large amount of organic pollutants, which will consume dissolved oxygen, destroy the ecological balance of water, and endanger the survival of fish a...
