Chemical law of wastewater treatment:
A chemical substance is added to the sewage, and a chemical reaction is used to separate and recover certain pollutants in the sewage or convert them into harmless substances. Commonly used methods include chemical precipitation, coagulation, neutralization, redox (including electrolysis), and the like.
1. Chemical precipitation method
A chemical substance is added to the sewage to cause it to exchange with a dissolved substance in the sewage to form a precipitate which is hardly soluble in water to reduce dissolved substances in the sewage. This treatment is commonly used in the treatment of industrial production wastewater containing heavy metals, cyanides and the like. Depending on the precipitant used, the chemical precipitation method can be divided into a lime method (also known as a hydroxide precipitation method), a sulfide method, and a bismuth salt method.
2. Coagulation method
Adding a coagulant to the water can make the colloidal particles in the sewage lose stability and condense into large particles and sink. Finely dispersed solid particles, milk oil and colloidal substances in sewage can be removed by coagulation. The method can be used to reduce the turbidity and chromaticity of sewage, remove a variety of high molecular substances, organic matter, certain heavy metal poisons (mercury, cadmium, lead) and radioactive substances, and can also remove eutrophic substances such as phosphorus. Soluble inorganic substances, in addition, can improve the dewatering performance of the sludge. When the coagulant alone can not achieve the desired water purification effect, in order to strengthen the coagulation process and save the amount of coagulant, it is often possible to add a coagulant at the same time.
3. Neutralization method
Used to treat acidic wastewater and alkaline wastewater. Alkaline substances such as lime, sodium hydroxide, limestone, etc. are added to the acidic wastewater to make the wastewater neutral. The alkaline wastewater can be neutralized by blowing flue gas containing CO2, and other acidic substances can be used for neutralization.
4. Redox method
Oxidizing and decomposing harmful substances in wastewater into harmless substances by using strong oxidizing agents such as liquid chlorine, ozone, potassium permanganate or by anodic reaction during electrolysis; using harmful substances in the waste water or cathodic reaction during electrolysis Reducing to harmless substances, the above methods are collectively referred to as redox methods.
