Embodiment Construction
[0027] In order to make up for the deficiencies of the existing automatic control system, the intelligent monitoring system in the following embodiments of the present invention combines the supporting equipment (water production pump, backwash water pump, ozone generator, etc.) The washing cycle and other equipment involved in this process are precisely controlled, so as to achieve the purpose of stable discharge of effluent water quality. Its control mode has three modes: local, remote and one-button automatic. In the one-button automatic mode, the operator only needs to set the corresponding parameters on the Chinese interface of the monitoring system according to the influent flow and water quality parameters, and then start it with one button, and can observe the dynamic display process flow chart, complete historical data records and equipment Alarm status reports, etc., and at the same time, remote monitoring of the system can be realized through the Internet or 4G netw...

The invention discloses an intelligent control system and a control method for an integrated sewage treatment device. The intelligent control system is used for achieving control of controlled devicesincluding a raw water lifting pump, an ozone generator, a nano ceramic membrane module, a nano ceramic membrane suction pump, a nano ceramic membrane backwashing pump, an activated carbon backwashing pump, a nano ceramic membrane chemical cleaning dosing pump, an electric valve and the like; the intelligent control system uses an STM32F107VBT chip as a core processor, and the control requirements are achieved by designing a peripheral circuit of the processor and inserting a process logic program in the processor. The high-efficiency control of a nano ceramic membrane sewage treatment systemis achieved, the stability of the operation of a nano ceramic membrane is greatly improved, the sewage treatment efficiency is improved, and meanwhile the energy consumption and the operation cost are reduced.
Description
Technical field: [0001] The invention relates to the field of automatic control of sewage treatment, in particular to an intelligent monitoring system for sewage treatment based on ceramic membrane nano-reactors, in particular to an intelligent control system and control method for sewage treatment integrated equipment. Background technique: [0002] At present, the water quality of sewage treatment in many areas in China is not up to standard, and the pipeline network in some areas is not perfect or the treatment capacity is less than the storage capacity of the sewage pipe network, which leads to the direct discharge of sewage. The integrated sewage treatment equipment meets the needs of the market. It has the advantages of convenient installation and transportation, Small footprint, fully automatic and unattended, etc., are favored by the majority of users in the field of small-scale sewage treatment. [0003] At present, my country's sewage treatment integrated assembly ...
