Description

Sewage automatic allocation system and its allocation method

The present invention provides an automatic sewage allocation system and an allocation method thereof, in particular, the use of an automatic sewage adjustment device to adjust the outflow of sewage from a plurality of buffer tanks, so that the water quality sensing value of the sewage in the mixing tank is maintained within a preset range, and then Reduce the burden of subsequent sewage treatment equipment treatment, thereby extending the life of the sewage treatment equipment.

According to the fact that with the rapid development of technology and industry, the environmental pollution problem has become more and more serious. Among them, water pollution is the most serious problem. Therefore, industries such as electroplating, food processing, dyeing and finishing, traditional industries, semiconductor industries, or high-tech industries will be more and more serious. Waste sewage is treated through the sewage treatment plant. When the sewage treatment plant treats the sewage, it will first distinguish the inflow pipelines according to the industry, and measure the inflow water quality and water quantity, and then combine multiple sewage sources. After the sewage is converged, the purification process such as sedimentation, mixing, aeration or filtration can be carried out. Finally, the purified water quality can be tested. If the measured water quality meets the discharge standard, it can be discharged to the external waters.

However, the amount of sewage discharged by various industries and the degree of pollution cannot be predicted. If a highly polluting industry suddenly discharges a large amount of highly polluted sewage to the sewage treatment plant, the sudden inflow of the highly polluted sewage is likely to cause the sewage treatment plant The purification equipment inside is damaged, and in order to cope with the sudden high pollution sewage, it is necessary to allocate manpower to add the dosage in the purification equipment, so that It adds a lot of extra manpower and drug administration costs. Moreover, since most of the high-polluting industries discharge sewage during the daytime, however, since the high-polluting industries do not discharge high-polluting sewage at night, the purification equipment should be used in the evening. During the period, only low-polluting sewage could be purified, resulting in a low utilization rate of the purification equipment, which could not be used effectively, and a lot of costs were spent in vain.

Therefore, how to try to solve the above-mentioned deficiencies and inconveniences of conventional use is the direction that relevant industries in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the inventor collected relevant information, and through multiple evaluations and considerations, he designed this automatic sewage water allocation system and its allocation method as the patentee of the invention.

The main purpose of the present invention is that the sewage automatic adjustment device can sense the water quality sensing value of the sewage in the multiple buffer tanks through a plurality of sensing modules, and transmit the sensed multiple water quality sensing values to the sewage automatic adjustment device The control module, and the control module will send a deployment signal to the multiple water flow regulators of the sewage automatic adjustment device according to the multiple water quality sensing values, so that the multiple water flow regulators can adjust the buffers respectively according to the received deployment signals The amount of sewage flowing out of the tank to the blending tank, so that the water quality sensing value of the sewage from the multiple buffer tanks into the blending tank is maintained within the preset range, and the sewage in the blending tank can be used by sewage treatment equipment. Purification work is carried out to meet the sewage discharge standards, because the water quality sensing value of the sewage in the mixing tank can be stably maintained within the preset range through the automatic sewage adjustment device, so as to avoid sudden high or excessive confluence in the mixing tank. Sewage with low water quality sensing value can further reduce the burden of sewage treatment equipment during processing, so as to extend the life of the sewage treatment equipment, and because the water quality sensing value of the sewage in the blending tank is stably maintained within the preset range, the subsequent follow-up can be stabilized The dosage of sewage treatment equipment during purification treatment, by This achieves the purpose of reducing the cost of sewage treatment.

The secondary purpose of the present invention is that the plurality of buffer tanks can automatically adjust the water output through the sewage automatic adjustment device, so as to extend the time for the high-concentration water quality sensing value sewage to be discharged into the mixing tank, thereby extending the sewage treatment equipment In order to increase the utilization rate of sewage treatment equipment, it can achieve efficient operation and reduce operating costs.

Another object of the present invention is that the plurality of buffer tanks can automatically adjust the water output through the sewage automatic adjustment device, so that the water quality sensing value of the sewage in the mixing tank is stably maintained within the preset range, and then the subsequent sewage treatment equipment purification is fixed. The dosage of the medicine during the treatment can save manpower for the treatment, so as to achieve the purpose of improving the purification operation, reducing the operating cost and operating convenience.
