An analysis method of an intelligent analysis system for sludge nitrification activity

Abstract

The invention provides an intelligent analysis system of the sludge nitrification activity, and an analysis method thereof. The system comprises a control panel, a PLC controller, and a reaction device arranged in a cabinet body, the bottom of the reaction device is connected with a water discharge tube, a water discharge solenoid valve, an aeration tube, an aeration head and an aeration solenoid valve respectively, the upper portion of the reaction device is sequentially connected with a water feeding tube, a water feeding solenoid valve, a water feeding pump, a dosing tube and a dosing pump, one end of the aeration tube is connected with the aeration head, and the other end of the aeration tube is connected with the solenoid valve and the aeration pump. The analysis method adopting the system comprises the following steps: calculating the sludge nitrification activity number by continuously monitoring the ammonia nitrogen value change within a period of time, and carrying out analysis calculating by adopting data analysis software on the basis of a least squares technique and a simulated approaching technique. The system is suitable for determining the nitrification activity of active sludge in the biological pool of a municipal sewage treatment plant, and the ammonia nitrogen nitrification rate of the active sludge, and substantially improves the detection rate and the real time monitoring efficiency of the ammonia nitrogen nitrification rate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an analysis method of an intelligent analysis system for sludge nitrification activity. Background technique [0002] The problem of eutrophication of water bodies has become increasingly prominent, and the discharge standards for nitrogen and phosphorus have become increasingly stringent. my country promulgated in 2002 the "Urban Sewage Treatment Plant Pollutant Discharge Standards" to increase the emission concentration limits of total nitrogen and total phosphorus. At present, the development level of my country's sewage treatment industry still lags behind developed countries. The main problems currently faced by my country's sewage treatment industry are the low energy efficiency of sewage treatment facilities and the low compliance rate of sewage treatment. Statistics show that as of 2009, China has built about 1993 sewage treatment plants. In additi...
