Abstract

The invention provides a high-efficiency phosphorus removing flocculant for sewage. The high-efficiency phosphorus removing flocculant for the sewage comprises the following components in parts by weight: 10-20 parts of ferric chloride, 22-30 parts of ferrous sulfate, 5-8 parts of triethanolamine, 5-10 parts of hydrogen peroxide and 40-50 parts of deionized water, and the sum of the parts by weight is 100. The high-efficiency phosphorus removing flocculant for the sewage, provided by the invention, has strong adaptability, a wide application range and a superior phosphorus removing effect; a large amount of hydroxide floc precipitate produced during hydrolysis has very large specific surface area and adsorption capacity and has a very strong adsorptive effect on negatively charged phosphate, hydrogen phosphate and dihydrogen phosphate contained in the sewage; through adsorption and bridging, colloids in the sewage can be condensed together, so that the phosphorus removing efficiency isguaranteed; in addition, the product performance is stable.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-efficiency flocculant for phosphorus removal for sewage and a preparation method thereof. Background technique [0002] Phosphorus is an essential element in living organisms, and at the same time, it is the main cause of eutrophication in water bodies, which will cause the loss of the purification function of water bodies and affect the production and living environment of human beings. High phosphorus content in wastewater will cause serious pollution, so it needs to be treated before discharge to reduce the phosphorus content in wastewater. [0003] In recent years, due to the gradual improvement of water quality standards and the further control of pollutant discharge, the state has further refined the first-level standards in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB 18918-2002) into first-level A and first-level B....
