Self-cleaning type ammonia-nitrogen wastewater treatment set device

Abstract

The invention relates to a high-concentration ammonia-nitrogen wastewater treatment set device, which comprises a dissolved medicine dissolution box, a wastewater flow stabilizing and flow guiding tube, a sand and stone exchange cleaner, filter materials, a sand blocking water distributor, sand and stone air stripping pipe, an air compressor output pipe, an air input pipe, a monitoring probe, an automatic control system and the like. The invention can treat the high-concentration ammonia-nitrogen wastewater which can not be treated by a physical chemical and biochemical method, at the same time, the defect that alkali addition, acid addition or temperature raising is needed during the high-concentration ammonia-nitrogen wastewater treatment by other methods for reaching the treatment effect can be avoided, the operation cost is reduced, and the area of the occupied ground is saved. The saturated filtering materials can be used as slow-release fertilizers for plants after being pulverized, and no secondary pollution is caused after the whole equipment operates to the filter material recovery.

Description

technical field [0001] The invention relates to wastewater treatment equipment, in particular to ammonia nitrogen wastewater treatment equipment capable of meeting the requirements of sewage discharge without adjusting the pH value, in particular to a self-cleaning ammonia nitrogen wastewater treatment complete set of filter media capable of self-cleaning. Background technique [0002] At present, with the growth of world population and the rapid development of industry, agriculture and animal husbandry, especially the wastewater discharged from production plants such as petroleum, chemical industry, food processing, animal husbandry, landfill leachate, chemical fiber, synthetic ammonia and urea, its composition is complex , and the content of ammonia nitrogen is high, if it is directly discharged into rivers, rivers, lakes, and seas without treatment, it will poison fish and aquatic organisms in the water, and even die in large numbers, and at the same time cause the lake to...
