Denitrification collaborative bio-doubling process

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a denitrification collaborative bio-doubling process. The bio-doubling process comprises a main system and an auxiliary system and is characterized in that the main system comprises an inflow water distribution system, a liquid level changing water outlet system, a variable frequency air blowing accurate aerating system, an independent stirring system, a pre-arranged denitrification selection tank, a main biochemical reaction pond, a reflux pump and a sludge discharging pump; the auxiliary system comprises an accurate aerating electric control system, an independent stirring system, a special-type agent feeding system, a temperature monitoring system, a PH monitoring system and a dissolved oxygen monitoring system. According to the denitrification collaborative bio-doubling process, chemical waste water can be effectively purified, an excellent water outflow effect can be achieved, hazard-free treatment is carried out on the sewage, environment benefits are created, reclaimed water is reused and certain economic efficiency is created.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a denitrification synergistic biological multiplication process. Background technique [0002] Chemical wastewater itself is a difficult problem in the environmental protection water treatment industry. At present, the main methods for treating refractory organic wastewater include chemical oxidation, extraction, adsorption, incineration, catalytic oxidation, biochemical methods, etc., but physicochemical methods and advanced oxidation solutions Facing the high cost of infrastructure and operation, only the biochemical process has mature technology, simple equipment, large processing capacity, and low operating cost, while the traditional biochemical process faces problems such as the effluent quality not meeting the direct reuse standard. Contents of the invention [0003] The purpose of the present invention is to provide biochemical treatment technology ...
