Abstract

The invention relates to a kind of wastewater depurator and its manufacturing method and application, which involves in sewage disposal environment. The wastewater depurator contains blend concave-convex stick soil, inorganic filling containing silicon dioxide, acidifying high-chemical valence metal salt and so on. After acidifying to PH 1-3, high-chemical valence metal salt solution evenly mixes with other components and dries, then it can be acquired. The wastewater depurator can make condensation and absorption function in a whole, and can make treating effictiveness basically not influenced by factors such as water-body condition, pollution extent, wastewater category and so on. And also it has stable treating effictiveness, wide scope of application, especially adapts to preliminary purifying treatment for industrial wastewater with bad pollution. The manufacturing method and the industrial art for water treatment are simple so that it is easy for operation, and in a result, it has wider extending application prospect.

Description

technical field

[0001] The present invention relates to a kind of water treatment agent, more specifically, relates to a kind of waste water purification agent containing clay mineral, its preparation method and the application of waste water treatment. Background technique

[0002] In the modern water treatment process, coagulation-flocculation treatment technology is still the technical solution with the highest utilization rate and better treatment effect. The core of the process is to make various fine impurities or toxic dissolved substances in the sewage It precipitates in the form of adsorption and aggregation, so it is easy to separate it from the water body by solid-liquid separation or filtration technology to achieve water purification. Under normal circumstances, the efficiency of this scheme is relatively high, but if it encounters sewage with complex pollution components and relatively large pollution load, the implementation of this process will encounter man...
