Flocculating agent

Abstract

The invention relates to a flocculating agent; the usage amount of the flocculating agent is less than that of the marketing products; and the flocculated deposits can be chemical substances for executing refuse treatment; the treated drain satisfies the environmental standard (BOD and COD). The flocculating agent is characterized by comprising 1 to 3 weight % of natural organic acids, 40 to 55 weight % of ammonium aluminum sulfate, 7 to 10 weight % of aluminum sodium sulfate, 8 to 15 weight % of acrylamide polymer with average molecular weight being 9 million to 10 million, 20 to 25 weight % of sodium carbonate (treated pH being set between 6.71 to 7.70); wherein, the natural organic acids are selected from natural organic acids of citric acid, lactic acid and ferrous lactate.

Description

technical field [0001] The present invention relates to a flocculant that flocculates and precipitates a small amount of drainage from engineering sites, domestic drainage from factories or households using food raw materials, and makes the treated drainage comply with environmental standards (BOD and COD). Background technique [0002] Currently, there is an environmental regulation law for the treatment of wastewater from construction sites and domestic wastewater from factories and households using food materials, but it is still the status quo that relies on public institutions such as sewers for treatment. [0003] In particular, there are drainage containing soil sludge from construction sites, drainage from factories such as noodle factories, rice washing water from households, drainage containing gorgon starch, etc., as domestic drainage using food raw materials. [0004] Therefore, although various flocculants are commercially available, there is still a problem tha...
