Problems solved by technology

In coagulation treatment, the coagulant used for different types of sewage is the key to the treatment, so many researchers are actively researching and developing new composite coagulants or flocculants, while the existing treatment of general industrial Various coagulants for sewage, domestic sewage and drinking water mainly use iron salts or aluminum salts, and do not make a good distinction for general industrial sewage, domestic sewage and drinking water; at the same time, the compounding process in sewage treatment is also a As an important unit, there are some problems with the compounding time and dosage in the compounding process. For example, in the process of treating general industrial sewage, domestic sewage and drinking water, there are coagulants and general industrial sewage, domestic sewage and drinking water. Problems such as the slow reaction and the coagulant not reacting with the suspended solids in the water caused the metal elements in the coagulant to remain in the water, resulting in secondary pollution. At the same time, the incomplete reaction of the coagulant also caused the waste, which increases the cost of sewage treatment

Embodiment Construction

[0012] Embodiments of the present invention, because different types of coagulants such as polyaluminum chloride, cationic polyacrylamide, diallyl dimethyl ammonium chloride or acrylic acid amine copolymers can react in a short time when mixed , to form an inorganic polymer form, so the coagulant and composite element (or composite substance) used in the present invention can be similar substances, but in specific use, the same substance cannot be used in the dosing pipeline 2 and the additional pipeline 3 at the same time As coagulant and compounding element.

[0013] Set a dosing pipeline on the sewage pipeline of flowing general industrial sewage, domestic sewage and drinking water, connect an additional pipeline on the side of the dosing pipeline, add coagulant through the dosing pipeline, and the added coagulant is polymerization Aluminum chloride may also be cationic polyacrylamide, diallyldimethylammonium chloride or acrylamine copolymer. And add composite elements thr...

Abstract

The invention relates to a general industrial sewage, domestic sewage and drinking water treatment method. According to the method, a coagulant is added into the sewage pipeline or at the outlet position through an agent spraying pipeline. The method is characterized in that the agent spraying pipe is connected to at least an additional pipeline, an composite element for improving the coagulant efficiency is added into the coagulant through the additional pipeline, the composite element and the coagulant are mixed, and the obtained mixture enters the sewage inside the sewage pipeline or at the outlet position, wherein the coagulant is poly aluminium chloride, cationic polyacrylamide, diallyl dimethyl ammonium chloride or acrylamide copolymer, and the composite element is cationic polyacrylamide, diallyl dimethyl ammonium chloride, acrylamide copolymer, activated silicic acid, calcium chloride or hydrochloric acid, and phosphoric acid or sulfuric acid.

Description

technical field [0001] The invention relates to a treatment method for general industrial sewage, domestic sewage and drinking water, and belongs to the technical field of sewage treatment. Background technique [0002] In general industrial sewage, domestic sewage and drinking water treatment and water purification, coagulation is one of the very important units. It uses coagulants to change the state of particles in water, so that suspended components and colloidal components in water are separated. Under certain conditions, flocs that can be separated by precipitation or air flotation are formed, and then this part of flocs is separated by precipitation or air flotation. In coagulation treatment, the coagulant used for different types of sewage is the key to the treatment, so many researchers are actively researching and developing new composite coagulants or flocculants, while the existing treatment of general industrial Various coagulants for sewage, domestic sewage an...
