Problems solved by technology

However, most of the inorganic and organic flocculants currently used are water treatment agents with a single function, such as aluminum-based flocculants such as polyaluminum, aluminum sulfate, and aluminum trichloride, and iron-based flocculants such as polyferric and ferric chloride. It only has coagulation and flocculation efficiency in water, but does not have such functions as oxidation and sterilization. It cannot effectively reduce COD, BOD, etc. in wastewater, and it is also difficult to remove heavy metal ions in wastewater. At the same time, the efficiency of coagulation and sedimentation is also very low. Also easily redissolved

Embodiment 1

[0028] The purification treatment agent for alkaline wastewater consists of three components A, B, and C, wherein the A component is calcium dihydrogen phosphate, aluminum sulfate, polyaluminum chloride, and polyferric sulfate, and the B component is Magnesium oxide, calcium sulfate, sodium silicate, the C component is polyacrylate, polyacrylamide, and the percentages of A, B, and C are 60%, 30%, and 10%.

[0029] In the A component, the weight ratio of calcium dihydrogen phosphate: aluminum sulfate: polyaluminum chloride: polyferric sulfate is 1: 1.5: 0.15: 0.25, and the particle diameter of the A component is 10-50 μm, and wherein 10 -20 μm accounts for 20%, 20-40 μm accounts for 50%, and 40-50 μm accounts for 30%; in the B component, the weight ratio of magnesium oxide: calcium sulfate: sodium silicate is 1:2:1, and The particle size of component B is 10-100 μm, and wherein 10-40 μm accounts for 20%, 40-70 μm accounts for 50%, and 70-100 μm accounts for 30%; In the C compon...

Abstract

The invention provides a purification treatment process for an industrial waste liquid. The process is characterized by comprising: adding a high-energy multiple-effect purification treatment agent in an amount of 3-5g for each litre of a to-be-treated industrial waste liquid; and stirring and purifying the industrial waste liquid in 3-7 minutes after being added, wherein the purification treatment agent is composed of three components in percentage by weight: 50-60% of A, 30-40% of B and 5-10% of C; the component A comprises calcium dihydrogen phosphate, aluminum sulfate, polyaluminum chloride and polymeric ferric sulfate; the component B comprises magnesium oxide, calcium sulfate and sodium silicate; the component C comprises polyacrylate and polyacrylamide. The treatment process not only can be used for efficiently and accurately adjusting the pH value of the wastewater, but also can be used for effectively oxidizing and removing organic or inorganic pollutants in the wastewater and can be further used for quickly and efficiently realizing flocculation and eliminating heavy metal ions in the wastewater.

Description

technical field [0001] The invention relates to the technical field of purification treatment of industrial waste water and waste liquid, in particular to an alkaline waste water purification treatment agent used in the purification treatment process of industrial waste liquid. Background technique [0002] In recent years, with the continuous development of our society and the rapid progress of science and technology, people's exploration in the field of chemical industry has become more and more in-depth, and various complex and high-concentration industrial production wastewater has also been produced. For example, in industries such as metallurgy, electroplating, and batteries, high-concentration alkaline wastewater is often produced, which also contains high-concentration inorganic salts and heavy metal ions. Especially in the technical fields of metallurgy, electroplating and painting, the industrial wastewater often contains a large amount of organic resins, surfactan...
