Abstract

The invention discloses a percolation biochemical treatment system for enhancing denitrification of a percolation system, which comprises a nitrification water collecting tank, a nitrification percolation biochemical unit, a denitrification water collecting tank and a denitrification percolation biochemical unit, wherein inorganic ammonia-nitrogen wastewater in the nitrification water collecting tank is intermittently, regularly and quantitatively or continuously lifted to the nitrification and percolation biochemical unit and the denitrification and percolation biochemical unit through a lifting pump for uniform water distribution, flows into the denitrification water collecting tank through a nitrification water outlet pipe, and then enters the denitrification and percolation biochemical unit through the lifting pump; zeolite powder in ceramsite in the nitrification percolation biochemical unit adsorbs ammonia nitrogen, calcite provides an alkali source, and cerium oxide is used as an oxygen storage material, so that the unfired ceramsite has the characteristics of adsorbing ammonia nitrogen, slowly releasing the alkali source and quickly reoxygenating, a biological membrane is easily hung on the ceramsite, and each ceramsite can be used as an independent nitrification unit to form a nitrification coupling effect; the nitration reaction time is shortened, and the nitration rate is increased.

Description

technical field [0001] The invention relates to the field of waste (sewage) water treatment, in particular to a diafiltration biochemical treatment system applied to enhanced denitrification of a diafiltration system. Background technique [0002] In recent years, with the rapid development of my country's economy and the in-depth advancement of industrialization, urbanization and agricultural modernization, more and more waste (sewage) water has been generated, seriously affecting the living environment. There are two main types of ammonia nitrogen in wastewater, one is ammonia nitrogen formed by ammonia water, and the other is ammonia nitrogen formed by inorganic ammonia, mainly ammonium sulfate and ammonium chloride. Generally divided into four types: organic nitrogen, ammonia nitrogen, nitrite nitrogen (NO 2 - ) and nitrate nitrogen (NO 3 - ). Nitrate nitrogen (NO 3 - ) mainly. The general formation of high ammonia nitrogen wastewater is caused by the coexistence...
