Description

technical field [0001] The invention relates to a water treatment device, in particular to a foundation pit yellow water treatment device. Background technique [0002] In recent years, with the construction of high-rise buildings, while meeting the needs of social and economic construction, a large amount of foundation pit yellow water has also been produced. The foundation pit yellow water contains a large amount of sulfate, iron ions, manganese ions, calcium ions, magnesium ions, Ammonia nitrogen, suspended solids, and organic matter, etc., have high turbidity and chromaticity. The ionic component is the product of dissolved mineral salt in water. Ammonia nitrogen is the reduction of nitrate to nitrite and ammonia under the action of microorganisms under anaerobic conditions, resulting in an increase in ammonia nitrogen. , sulfate and suspended solids are the sand exploration companions in the process of pumping yellow water from foundation pits. A large number of pollut...
