Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and relates to a comprehensive pool wastewater treatment system and method based on pH intelligent control. Background Art

[0002] The incoming water of the power plant industrial wastewater system generally includes regular wastewater and non-regular wastewater. The incoming water of the industrial wastewater treatment system varies from power plant to power plant, and generally includes various production wastewaters such as equipment cooling water, slag system overflow water, demister flushing water, circulating water, and unit drainage tank collected water. Generally, for industrial wastewater with unqualified pH value and suspended solids, the general process is "wastewater storage tank (box) → pH adjustment tank (box) → mixing tank (box) → clarifying tank (box) → final neutralization tank → clean water tank → recycling or discharging" or "wastewater storage tank (box) → pH adjustment tank (box) → mixing tank (box) → clarifying tank (box) → final neutralization tank → clean water tank → filter → recycling". However, in actual pH value adjustment, acid and alkali are usually added according to experience by metering pumps, and finally the pH value of the wastewater is controlled within a reasonable range and then recycled to each water use system. In addition, general adjustment tanks, neutralization tanks, pre-sedimentation tanks, clarifying tanks, etc. are all set separately, and equipment connections such as pipelines, pumps, and valves are used to complete the entire treatment process. The traditional treatment methods and process equipment layouts have large equipment floor areas, are not concentrated, a certain number of lift pumps and long-distance pipelines will be set between each treatment unit, and there is no liquid level interlock protection mechanism between each treatment unit, and overflows and other situations may occur; furthermore, the pH value adjustment unit in the industrial wastewater treatment process is crucial. The traditional treatment method is generally to add acid and alkali by metering pumps and then regularly and frequently sample and measure the pH value of the wastewater to check whether the amount of acid and alkali added is sufficient. At the same time, there is also a risk of excessive addition of acid and alkali in this operation, further causing waste of chemical drugs and increase in labor costs.

[0003] Based on the above problems, there is a need to design a comprehensive pool wastewater treatment system based on pH intelligent control, which is used to automatically and accurately control the acid addition and alkali addition operations in the industrial wastewater treatment process, intelligently adjust the pH value of the wastewater, and better supply the downstream water use system. Moreover, by using the staggered layout, the effluent from the previous treatment unit can flow into the next treatment unit by gravity, saving the cost of lift pumps that must be set in the conventional layout. This method can provide a theoretical basis for treating industrial wastewater with unqualified pH value and suspended solids, and reduce the large number of repeated tests of experimental personnel, thereby saving manpower, energy, and drug consumption. Summary of the Invention

[0004] The purpose of the invention is to overcome the above-mentioned disadvantages of the prior art, and provide a comprehensive pool wastewater treatment system and method based on pH intelligent control. This system and method can accurately control the acid addition and alkali addition operations of wastewater, and the amount of acid and alkali added is controlled relatively accurately.

[0048] Embodiment 2

[0049] Reference Figure 1 and Figure 2 According to the present invention, the comprehensive pool waste water treatment method based on pH intelligent control includes the following steps:

[0050] The influent wastewater enters the pre-sedimentation tank 2, and the residence time is set to 30 minutes. The sediment after pre-sedimentation is discharged through the sludge discharge port of the pre-sedimentation tank 2 and merged to go to the sludge treatment unit of other water use systems for further treatment. Inside the pre-sedimentation tank 2, there is a first partition plate 3-1 and a first pH meter 4-1. The first partition plate 3-1 is used to protect the pH meter from being damaged. The pre-sedimented wastewater output from the pre-sedimentation tank 2 flows into the first regulation tank 6 by gravity. A second pH meter 4-2 is arranged in the first regulation tank 6 to measure the pH value of the wastewater in the first regulation tank 6 and determine whether the pH value of the wastewater in the first regulation tank 6 is within the set range of 6-9. When it is within the set range of 6-9, the wastewater is directly sent to the second regulation tank 8, and the wastewater pH value measurement program of the second regulation tank 8 is started by controlling the feedback system 1. The wastewater pH values of the pre-sedimentation tank 2, the first regulation tank 6, and the second regulation tank 8 are automatically read every 3 minutes. The pH value of the wastewater in the second regulation tank 8 is measured by the third pH meter 4-3, and the measured pH value of the wastewater in the second regulation tank 8 is compared with the set range of 6-9 to determine whether it is within the set range. If the wastewater pH value in the second regulation tank 8 is within the set range of 6-9, the wastewater is directly sent to the clear water tank 10, and the wastewater pH is measured every 20 minutes in the clear water tank 10, and the measured value is used as the influent reference index for downstream water use systems. When the measured pH value of the wastewater in the first regulation tank 6 or the second regulation tank 8 is not within the set range of 6-9, the acid and alkali addition program is automatically started to make it within the set range of 6-9. For example, when the wastewater pH value is less than the lower limit of the set range, the required amount of alkali is automatically calculated according to the wastewater volume and the measured pH value, and the alkali solution is accurately added through the second metering pump 12-2 until the wastewater pH value is within the set range. When the measured pH value of the wastewater is greater than the upper limit of the set range, the required amount of acid is automatically calculated according to the wastewater volume and the measured pH value, and the acid is accurately added through the first metering pump 12-1 until the measured wastewater pH value is within the set range.

[0051] It should be noted that the whole process of the present invention is controlled by the control feedback system 1, which is used for the opening and closing of various valves and metering pumps, can accurately control the acid and alkali addition operations in the industrial wastewater treatment process, intelligently adjust the wastewater pH value, better supply the downstream water use systems, provide a theoretical basis for treating industrial wastewater with unqualified pH value and suspended solids, and reduce a large number of repeated test times of test personnel, thereby saving manpower, energy and drug consumption.
