Abstract

The invention discloses a comprehensive type sewage treating agent with a phosphorus removing and ammonia-nitrogen removing compound function. The comprehensive type sewage treating agent is preparedfrom the following materials in mass percent: 3% to 15% of oxidizing agent, 3% to 10% of ammonia-nitrogen biological nitrification carbon source synergist, 1% to 5% of ammonia-nitrogen flocculation remover, 70% to 90% of phosphorus and ammonia-nitrogen removing compound inorganic flocculant and 1% to 5% of organic flocculant. The comprehensive type sewage treating agent disclosed by the inventioncan effectively remove phosphorus and ammonia-nitrogen in the sewage through a combined comprehensive mode of chemical oxidation ammonia-nitrogen removal of the oxidizing agent, synergistic biologicalnitrification ammonia-nitrogen removal of a carbon source and physical flocculation phosphorus removal and ammonia-nitrogen removal as well as synergistic effect of all the components. Furthermore, the comprehensive type sewage treating agent has the advantages of good comprehensive treatment effect, quick reaction speed, remarkable reduction of comprehensive treatment cost, simpleness in use, wide use range, ability in achieving effective treatment on aggregative indicators of the sewage and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a comprehensive sewage treatment agent with compound functions of phosphorus and ammonia removal. Background technique [0002] With the increase of human development and utilization of environmental resources and the acceleration of industrial and agricultural production scale, a large amount of domestic sewage and industrial sewage containing phosphorus and ammonia nitrogen are discharged into natural water bodies, which increases the eutrophication of water bodies and brings great harm to industries, The water used in agriculture, aquaculture, tourism and daily life has brought great harm. The removal of ammonia nitrogen and phosphorus has also become the most critical control index in the field of water treatment. How to effectively and comprehensively reduce the impact of ammonia nitrogen and phosphorus in sewage on Environmental protection and water tre...
