Environment-friendly medicament for industrial sewage treatment and preparation method thereof

Abstract

The invention discloses an environment-friendly medicament for industrial sewage treatment. The environment-friendly medicament is prepared from the following raw materials in parts by weight: 1.5 to 3 parts of organic alcohol, 12 to 24 parts of city sludge, 1 to 4 parts of soybean meal, 2 to 6 parts of straw, 5 to 9 parts of folium ginkgo, 0.5 to 3 parts of activated carbon, 2 to 5 parts of graphite, 12 to 20 parts of polyferric sulfate, 6 to 10 parts of kieselguhr, 3 to 6 parts of epoxy resin, 8 to 18 parts of acetic acid, 1 to 3 parts of vitamin C, and 8 to 15 parts of metacrylic acid ester. The invention also discloses a preparation method of the medicament. According to the environment-friendly medicament for the industrial sewage treatment and the preparation method thereof provided by the invention, the raw materials are wide in source and low in cost, the preparation process is simple, and the production cost is low; the city sludge and the straw are adopted, so that the aims of recovering and recycling wastes are achieved; the components play a synergic effect, so that the medicament can be used for flocculating and settling heavy metal ions, COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand), the settling speed is fast, the corrosion of discharged water on the equipment is reduced, and the medicament has favorable economic benefit and social benefit.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an environmental protection agent for industrial sewage treatment. Background technique [0002] Sewage treatment technology plays a very important role in water saving, energy saving and other issues, but at the same time, the use of environmental protection chemicals for sewage treatment also has a certain impact on the environment. In the cooling water system, in various occasions where the water temperature is higher than the ambient temperature, the scaling of calcium carbonate and other inorganic salts will bring serious consequences. In recent years, in the field of water treatment, the application of alkaline water treatment technology that does not adjust the pH value is increasing. Among them, the addition of corrosion and scale inhibitors, low-phosphorus, and phosphorus-free formulations are more and more widely used. Phosphorus-free green Environmentally friendly chem...

Problems solved by technology

[0003] Existing water treatment technology has treated harmful substances such as heavy metals in industrial wastewater, but it cannot achieve a good removal effect on harmful substances other than heavy metals in wastewater, especially when there is industrial circulating water that is difficult to remove. The problem of harmful substances, the existing sewage treatment chemicals have slow treatment speed, poor treatment effect and high cost of use, all of which have brought inconvenience to the enterprise
