Environment-friendly water treatment flocculation material and preparation method thereof

Abstract

The invention discloses an environment-friendly water treatment flocculation material and a preparation method thereof. The environment-friendly water treatment flocculation material comprises a Chinese herbal medicinal active antibacterial component and a chemical adsorption component; the Chinese herbal medicinal active antibacterial component is prepared from the following raw materials in parts by weight: 6 to 12 parts of radix angelicae, 4 to 10 parts of mint, 2 to 8 parts of lonicerae japonicae flos, 4 to 10 parts of folium artemisiae argyi, 6 to 12 parts of broom cypress fruit, 8 to 14 parts of pomegranate peel and 10 to 16 parts of castor oil; the chemical adsorption component is prepared from the following raw materials in parts by weight: 20 to 32 parts of polyacrylamide, 16 to 28 parts of activated carbon, 10 to 22 parts of lignin, 4 to 10 parts of aluminium oxide, 6 to 12 parts of polyferric chloride, and 4 to 10 parts of polyferric sulphate. The environment-friendly water treatment flocculation material can effectively remove high-concentration organic pollutants and suspended solids in a wastewater treatment system; the chemical adding amount is small; the decolouration performance is excellent; the decolouration rate is high; the floc settling velocity is high; the floc size is small; the environment-friendly water treatment flocculation material is safe and environment-friendly, is low in wastewater treatment energy consumption, low in treatment cost, and is helpful to improve the current situation of wastewater treatment in China.

Description

technical field [0001] The invention relates to the field of water treatment environment-friendly materials, in particular to an environment-friendly water treatment flocculation material and a preparation method thereof. Background technique [0002] The main causes of water pollution in my country are: 1. Industrial pollution sources. Industrial wastewater is an important source of pollution in water areas. It has the characteristics of large volume, wide area, complex composition, high toxicity, unsuitable purification, and difficult treatment; 2. Agricultural pollution sources. Agricultural pollution sources include Livestock manure, pesticides, chemical fertilizers, etc.; China is one of the countries with the fastest soil erosion in the world. The annual topsoil loss is about 5 billion tons, and two thirds of the lakes are affected by eutrophication in varying degrees, causing algae and other biological Abnormal reproduction, causing changes in water transparency and dis...

[0003] Coagulation sedimentation is currently the most commonly used physical and chemical treatment method in the water treatment process, and it is a key link in the treatment process. Its treatment effect is closely related to the type and performance of the coagulant; coagulants can be divided into inorganic low molecular Coagulants, inorganic polymer coagulants and organic polymer coagulants, these types of coagulants have certain de
