Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide a coagulant for industrial water pretreatment in view of the deficiencies of the above-mentioned prior art. The water quality requirements have better solved the problems caused by the slow hydrolysis speed of the coagulant, many hydrolysis intermediate products, small floc particle density, and high content of metal ions in the effluent when conventional aluminum salts, iron salts and other coagulants are used in water treatment. The problem of poor coagulation effect

Embodiment Construction

[0028] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] There are also some patents in the prior art aimed at providing coagulants for water treatment. For example, the application number is 201310569471.X, and the invention name is a patent for a sewage treatment agent, which contains aluminum sulfate and aluminum phosphate as inorganic coagulant. When the effluent is used for drinking water, aluminum salts will introduce excessive aluminum ions into the tap water,...

Abstract

The invention relates to equipment for pretreating industrial water. The equipment comprises a flocculating agent blending tank, a flocculating sedimentation tank and a water reservoir, wherein the flocculating agent blending tank is connected with the flocculating sedimentation tank by a pipeline I; the water reservoir is connected with the flocculating sedimentation tank by a pipeline II; a flow sensor I is arranged at one port, which stretches into the flocculating sedimentation tank, of the pipeline II; and a flow sensor II is arranged at one port, which stretches into the flocculating sedimentation tank, of the pipeline I. The water inlet pipelines are provided with the sensors so that the adding amount of a flocculating agent is controlled; two feeding holes are formed in the flocculating agent blending tank so that two main components of a flocculating agent are blended according to the amounts and the flocculating agent added into the flocculating agent blending tank is adjusted, and the working amount of manual labor is saved; the sensors are used for working and are used for monitoring the adding amount of the flocculating agent so that the whole treatment work can be continuously operated; and furthermore, the waste caused by manual errors is reduced and the working period is prolonged, the production efficiency is improved and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of industrial water pretreatment, in particular to equipment for industrial water pretreatment. Background technique [0002] Industrial water usually includes process water, boiler water, washing water, and cooling water, but mainly boiler water and cooling water. The water quality requirements of boiler water vary according to the working pressure and temperature of the boiler. No matter what kind of boiler water is used, it has strict restrictions on the hardness of water. Anything that can cause corrosion, scaling and Most or all of the impurities such as dissolved oxygen, soluble silicon dioxide, iron and residual chlorine that cause the phenomenon of soda and water to poison the ion exchange resin should be removed. [0003] The average industrial cooling water consumption accounts for about 67% of the total industrial water consumption, among which the petroleum, chemical and steel industries are the...
