Head loss monitoring-controlling system for aeration biofilter

Abstract

The invention provides a head loss monitoring-controlling system for an aeration biofilter. The system comprises a monitoring module, a controlling module and a backwashing system, the monitoring module comprises a first monitoring device for monitoring the pressure of the water inlet of an aeration biofilter in real time and a second monitoring device for monitoring the pressure of the water outlet of the aeration biofilter in real time; and the controlling module receives pressure signals collected by the first monitoring device and the second monitoring device. According to the analysis andprocessing results of the pressure signals transmitted to the controlling module by the first monitoring device and the second monitoring device, the backwashing system is controlled to carry out backwashing action on the aeration biofilter, so that the head loss of the aeration biofilter returns to normal. According to the invention, real-time on-line monitoring and identification control on thehead loss abnormity of the aeration biofilter can be easily realized, and the purposes of timely, accurate and intelligent judgment and efficient and reasonable control processing on the head loss abnormity of the aeration biofilter are achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and more specifically relates to a head loss monitoring and control system for biological aerated filters. Background technique [0002] Biological aerated filter is a sewage treatment equipment that uses biofilm method to treat sewage, and integrates biodegradation and solid-liquid separation. At present, when using the biological aerated filter as the sewage treatment equipment, the granular filler with a relatively high specific area is usually filled in the biological aerated filter as the carrier of the biofilm growth, and the lower part of the biofilm filter layer is aerated. It can provide oxygen source for the microorganisms on the particle packing carrier, so that the organic pollutants in the sewage can be biodegraded under the action of the biofilm on the surface of the particle packing, so as to achieve the purpose of sewage purification. However, with the extension of the wo...
