Abstract

The invention discloses a phosphorus polluted wastewater treatment adsorbent as well as a preparation method and application thereof. The phosphorus polluted wastewater treatment adsorbent is preparedfrom the following raw materials in parts by weight: 20 to 30 parts of maca powder, 15 to 20 parts of docusate sodium, 10 to 20 parts of fly ash, 6 to 15 parts of calcium formate, 6 to 11 parts of ethylene glycol salicylate, 18 to 28 parts of mannitol, 5 to 11 parts of malic acid and 40 to 65 parts of water. The phosphorus polluted wastewater treatment adsorbent disclosed by the invention can beused for treating phosphorus polluted wastewater and treating heavy metal wastewater relatively well; the raw materials do not easily cause secondary pollution and the phosphorus polluted wastewater treatment adsorbent has phosphorus removal and heavy metal adsorption functions; energy-saving and environment-protection requirements can be met relatively well and the phosphorus polluted wastewatertreatment adsorbent has relatively high popularization value.

Description

technical field [0001] The invention relates to an adsorbent, in particular to an adsorbent for treating phosphorus-polluted wastewater and its preparation method and application. Background technique [0002] Excess phosphorus in water mainly comes from fertilizers, agricultural waste and urban sewage. According to data, the phosphate content of surface water has increased by 25 times in the past 15 years, and 60% of the phosphate entering water bodies in the United States comes from urban sewage. The main source of phosphate in urban sewage is detergent. In addition to causing eutrophication of water bodies, it also makes many water bodies produce a lot of foam. On the one hand, the excess phosphorus in the water body is also the most important aspect, which comes from external industrial wastewater and domestic sewage. On the other hand, it also has its endogenous effect, that is, the sediment in the water body will release phosphate in the reduced state, thereby increa...
