Problems solved by technology

[0005] The purpose of the present invention is to overcome the defect of judging whether dosing is needed in the sewage treatment tank based on the single factor of effluent water quality in the prior art, and to provide a monitoring method for automatically monitoring the dosing sewage treatment system and the content of the medicine. Fluorescence monitoring equipment is organically combined to judge whether it is necessary to add chemicals to the sewage treatment tank through the dual results of water quality analysis and fluorescence monitoring, which avoids the accident of judging only by a single factor, improves the accuracy of dosing, and improves the efficiency of sewage treatment

Abstract

The invention discloses a dosed sewage treatment system with an automatic monitoring function. The system comprises a computer, a PLC, a sewage treatment tank, a dosing pump for dosing in the sewage treatment tank, an automatic sampler, an automatic grabbing arm, a water quality tester and fluorescence monitoring equipment, wherein a stirring device is arranged in the sewage treatment tank; a sampling port is formed in the sewage treatment tank, a water outlet pipe connected with the sampling port conveys a water sample to a sampling bottle, the automatic sampler and the automatic grabbing armare connected with the computer through leads, and automatic sampling is realized through a program installed on the computer; a sample outlet is arranged at the bottom of the sampling bottle; the sample outlet is connected with the water quality tester through a guide pipe, and the automatic grabbing arm is used for carrying a sample storage device to the fluorescence monitoring equipment for fluorescence intensity analysis. The system has the benefits as follows: the agent addition accuracy is improved, the agent waste is reduced and the cost is reduced; meanwhile, a stirring sheet device with an agent outlet is adopted, so that agents are mixed more uniformly in the sewage treatment tank, and the treatment efficiency and the effluent quality are improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for automatically monitoring a chemical-adding sewage treatment system and the content of the chemical. Background technique [0002] With the acceleration of urbanization and industrialization in our country, the discharge of waste water in the country has also increased year by year, resulting in the continuous deterioration of natural water bodies and the severe situation of water resource pollution. The contradiction between my country's water resources shortage, severe water pollution control situation and the sustained growth of the national economy and the gradual improvement of people's living standards has become increasingly prominent. Water pollution and water resource shortages have become serious constraints to the sustainable development of my country's economic society. With the rapid development of my country's economy, environmental protection h...
