NITROGEN REMOVAL METHOD OF ORGANIC WASTEWATER WITH HIGH CONCENTRATION IN LIQUID PHASE CORROSIVE METHOD

摘要

The present invention effectively removes nitrogen compounds in the effluent by treating liquid parts to be purified water according to the water quality standard after solid-liquid separation of manure, livestock manure or other high-concentration organic sewage, which takes a large part as environmental pollution sources. It relates to a nitrogen removal method of high concentration organic sewage to be treated and removed.;In one bioreactor (liquid corrosion bath), agitation (oxygen treatment) and aeration (aerobic treatment) are performed alternately, but operate two cycles to several cycles a day, and high concentration organic sewage (raw water) input is stirred every time (oxygen treatment). At the same time, and at least before the stopping of the stirring, the input amount at each stirring is the total amount of high concentration organic sewage to be treated per day divided by the number of cycles per day. The present invention relates to a nitrogen removal method of high concentration organic sewage, which is discharged during aerobic treatment (aeration) at a time 24 hours a day.
