Abstract

The invention discloses a novel water treatment agent and a preparation method and application thereof. The water treatment agent consists of a water quality conditioning agent and a magnesium-iron composite decoloring flocculating agent; the water quality conditioning agent is prepared by the following formula which comprises the components in parts by weight: 50-90 parts of calcium oxide, 10-40parts of aluminium potassium sulfate and 10-30 parts of magnesium sulfate heptahydrate; and the magnesium-iron composite decoloring flocculating agent is prepared by the following formula which comprises the components in parts by weight: 5-30 parts of ferrous sulphate, 60-90 parts of magnesium sulfate heptahydrate and 0.1-5 parts of flocculation increasing agent. The water treatment agent can beused for waste water treatment of industrial waste water, especially in the leather industry, the fur industry and the textile printing and dyeing industry with serious pollution. When being used forsewage treatment, the water treatment agent has little investment, fast effect, good treatment effect and no secondary pollution; and the water treatment agent has low cost, and the production methodis simple and convenient and has no pollution.

Description

technical field [0001] The invention relates to a new type of water treatment agent, which includes a new iron-magnesium composite decolorizing flocculant and its matching water quality regulator; the invention also relates to a preparation method of the water treatment agent, and the The application of water treatment agent in sewage treatment, especially in the treatment of acidic colored industrial wastewater. Background technique [0002] Sewage treatment, especially the treatment of heavily polluted leather, fur and textile wastewater has always been a problem that plagues the development of these industries. At present, the world's water treatment chemicals are developing in the direction of high efficiency, low toxicity, no secondary pollution, specialization, compounding, and multifunctionality. [0003] Traditional flocculants are divided into inorganic and organic. Inorganic flocculants mainly include polyaluminum chloride, ferric chloride, etc., while organic flo...
