Description

An intelligent automatic sewage treatment system

technical field

The utility model relates to a sewage treatment system, in particular to an intelligent automatic sewage treatment system.

Background technique

Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment according to the degree of treatment. Generally, the degree of sewage treatment is determined according to the water quality and the whereabouts of the treated water. Primary treatment refers to the removal of suspended solid pollutants in sewage, and most physical treatment methods can only meet the requirements of primary treatment. After primary treatment, BOD can generally be removed by about 30%, which does not meet the discharge standard. Primary treatment belongs to the pretreatment of secondary treatment. Secondary treatment refers to the removal of colloidal and dissolved organic pollutants (BOD, COD substances) in sewage. The removal rate can reach more than 90%, so that organic pollutants can meet the discharge standards. Currently, short fibers are widely used. The removal rate of suspended matter reaches 95%, and the water effluent effect is good. Tertiary treatment refers to the further treatment of refractory organic matter, nitrogen and phosphorus and other soluble inorganic matter that can lead to eutrophication of water bodies. The main methods are biological nitrogen and phosphorus removal, coagulation sedimentation, sand filtration, activated carbon adsorption, ion exchange and electrodialysis.

The basic characteristics of intelligent automation technology are intelligence and integration. Intelligentization refers to the use of artificial intelligence, knowledge engineering, neuron network theory, large system theory, etc., to make the system have some human intelligence, which can replace or expand human mental work, and realize the automation of mental work; integration refers to the integrated Information technology, system control technology, software technology, microelectronics technology, optoelectronics technology, communication technology, sensing technology, robotics technology and expert system and other technology groups are integrated to achieve integration or synthesis.

The existing sewage treatment system has the shortcomings of intelligence, low automation level, low sewage treatment efficiency and poor effect. Therefore, it is urgent to develop an intelligent, high automation level, high sewage treatment efficiency and good effect intelligent automatic sewage treatment system. processing system.

Working principle: When the device is working, the sewage is put into the sump first, and the sewage enters the sump and is first filtered through the coarse grid plate, and then filtered through the fine grid plate. After filtering for a period of time, some large pieces of floating or suspended matter remain on the coarse grid plate and the fine grid plate, then the upper and lower cylinders are controlled to work, and the upper and lower cylinders first drive the second-stage telescopic rod to move upward. The second-stage telescopic rod drives the fine grid plate to move upwards, and then the coarse grid plate moves upward again, and the coarse grid plate and the fine grid plate move out of the sump. Just clean up some floating or suspended matter remaining on the coarse and fine grid plates. The operator controls the lifting pump I to start working, and the lifting pump I lifts the filtered sewage in the sump to the air flotation tank through the sewage pipe I.

At the same time, the fan is started to work, and the fan pours gas into the inlet pipe I and the inlet pipe II through the main inlet pipe, and then the aerator head I injects the gas into the aerobic area. The microorganisms in the aerobic zone further decompose the organic matter in the sewage. When the liquid level of the treated sewage in the aerobic zone is higher than the partition II, it will automatically overflow into the sedimentation zone. The sewage is settled again in the sedimentation area, and the sludge pump III is controlled to start working, and the sludge pump III discharges the sludge deposited at the bottom of the sedimentation area into the sludge thickening tank through the sludge discharge pipe II. After the sedimentation treatment in the sedimentation area is full, the sewage enters the filter tank through the sewage pipe III, and the aeration head II injects gas into the filter tank, and the sewage and the gas react again.
