Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment, and in particular relates to a movable lime coagulation and clarification treatment device and method based on intelligent dosing. Background Art

[0002] Industrial wastewater treatment and reuse has become a growing trend in wastewater treatment. Lime coagulation and clarification technology is the mainstream technology for treating and reusing high-hardness water and industrial wastewater. Lime coagulation and clarification removes hardness, alkalinity, organic matter, microorganisms, colloids, suspended solids, mud, and sand from raw water through a combination of chemical coagulation, flocculation, sedimentation, and clarification. Currently, this technology is the primary treatment process for boiler feed water treatment systems in power plants.

[0003] Chinese patent application publication number CN105776472A discloses a dosing control device and method for a sewage treatment production line. The device includes an inlet suspended solids sensor located at the inlet of a coagulation reaction tank, an outlet suspended solids sensor located at the outlet of a sedimentation tank, and a dosing control system. The inlet suspended solids sensor and the outlet suspended solids sensor are both connected to the dosing control system and transmit inlet and outlet suspended solids concentration signals, respectively, to the dosing control system. The dosing control system is connected to a coagulant delivery pump and a coagulant aid delivery pump, respectively, and controls the output of the coagulant and coagulant aid based on the inlet and outlet suspended solids concentration signals. However, the device still has deficiencies in intelligent control, lacking the ability to comprehensively monitor water quality parameters and adaptively control them. Chinese patent application publication number CN111635053A discloses a zero-discharge desulfurization wastewater treatment system and method. The system includes a regulating tank, an integrated pretreatment unit, a microfiltration unit, a nanofiltration unit, a high-pressure reverse osmosis unit, an ultra-high-pressure reverse osmosis unit, a horizontal tube falling film concentration unit, and an evaporation crystallization unit. These components are connected sequentially according to the treatment direction of the desulfurization wastewater, achieving zero wastewater discharge, reducing the scale of the evaporation system, lowering the energy consumption of the evaporation crystallization process, and improving the purity of the crystallized salt. However, the system still needs to be improved in terms of treatment efficiency and quality, especially in terms of the concentration and crystallization of the nanofiltration product water.

[0004] However, traditional lime coagulation-clarification treatment technology suffers from numerous challenges. First, it relies on manual experience to adjust dosage, resulting in low dosage accuracy and lags in manual adjustments. This can easily lead to overdosing (wasting 15%-30% of the reagent) or underdosing (impairing treatment effectiveness), resulting in low efficiency and large sludge volumes. Second, existing lime softening treatment equipment is primarily a steel-concrete structure with decentralized processes. Lime addition, coagulation, and clarification require multiple units, occupying a large area and being immobile. Third, the investment is high and the system automation is low. The control system relies solely on a single parameter (such as pH), making it difficult to adapt to complex water quality fluctuations. Furthermore, the high unit investment and operating cost per ton of water used for treating small water volumes hinder its widespread application. To address these issues, a small, intelligent, high-precision, and adaptive integrated lime coagulation-clarification treatment device suitable for small water volumes is urgently needed. Such a device should feature real-time water quality monitoring, intelligent dosage decision-making, and convenient water volume control. It should enable automated treatment without human intervention, improve treatment efficiency, reduce operating costs, and address many of the shortcomings of traditional technologies.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a movable lime coagulation and clarification treatment device based on intelligent dosing. The first-level rapid coagulation tank realizes the rapid neutralization reaction of lime milk and wastewater. The second-level slow flocculation and concentration tank strengthens the floc sedimentation through a two-stage series overflow structure. The tubular membrane filtration device controls the circulation flow through the pressure difference to prevent membrane pollution, ensure that the turbidity, hardness and other indicators of the produced water meet the standards, and can be directly reused. The circulation design of the tubular membrane filtration and the second-level flocculation tank improves the solid-liquid separation efficiency, reduces the residual suspended matter, colloids and calcium and magnesium precipitates, and reduces the sludge discharge. The three modules of monitoring, dosing control and treatment work together to achieve dynamic response and solve the waste of reagents caused by manual adjustment lag. All treatment units are integrated in a standard container, without the need for civil construction, shortening the installation time, and can be moved as needed, which is suitable for emergency water supply, temporary projects and other scenarios. The modular structure supports flexible expansion and can be stacked with modules such as ozone oxidation and activated carbon adsorption to deal with complex pollution such as heavy metals and organic matter. It can be used for industrial wastewater treatment, rural drinking water softening, and circulating cooling water bypass treatment. Through intelligent dosing and modular expansion, it can adapt to different water quality treatment requirements. Through the technical combination of "intelligent monitoring - adaptive control - efficient treatment - modular integration", this device solves the problems of extensive dosing, large space, difficult mobility, and complex operation and maintenance in traditional lime coagulation treatment. It has significant technical advantages and economic value in small water volume treatment scenarios.

[0017] Furthermore, the intelligent monitoring module collects water quality data (alkalinity, hardness, pH value) in real time through sensors such as alkalinity meters, hardness meters, and pH meters in the water inlet / water production pipelines, providing a basis for precise regulation for the intelligent control unit, avoiding the lag problem of traditional manual adjustment and reducing chemical waste by 15% to 30%.

[0019] Furthermore, the tubular membrane intelligent filtration device automatically adjusts the circulation flow through the inlet and outlet pressure difference, preventing pollutants from clogging the membrane pores, extending the service life of the membrane assembly, and reducing operation and maintenance costs.

[0020] Furthermore, a sludge discharge port is set at the bottom of the secondary flocculation tank to automatically discharge sludge regularly; the membrane component circulation flushing design reduces the frequency of manual cleaning, the cost of steel structure equipment is lower than that of traditional concrete equipment, and the operation and maintenance costs are significantly reduced.

[0021] Furthermore, the device size is adapted to 1~50m 3 / h processing capacity, and the floor space occupied is only 1 / 3 of the traditional steel-concrete structure. It is particularly suitable for decentralized small water volume scenarios such as drinking water softening in villages and towns, circulating cooling water bypass treatment, etc., reducing the unit price of project investment and the operating cost per ton of water.

[0022] The present invention also discloses a method for using the above-mentioned movable lime coagulation and clarification treatment device based on intelligent dosing, which automates the entire process from sterilization and coagulation to membrane separation and pH adjustment, saves operators, reduces labor costs, reduces effluent hardness, and improves reuse rate.

It supports cloud-based data upload and remote parameter correction, allowing operators to monitor equipment status in real time, reducing on-site inspection workload. When the turbidity of the produced water exceeds the standard, an alarm is automatically triggered and the dosing amount is adjusted, reducing the risk of failure and improving system reliability.

[0024] Furthermore, historical data is used to train a dosing prediction model to respond to sudden changes in water quality in advance, avoid accidents involving exceeding standards, and replace manual experience-based judgment.

After entering the secondary slow flocculation and concentrating tank, the wastewater flows slowly within the concentrating tank. The first and second slow flocculation and concentrating tanks overflow into the second slow flocculation and concentrating tank, and then into the tubular membrane intelligent filtration device. The tubular membrane intelligent filtration device controls the system circulation flow by monitoring the turbidity of its produced water and the pressure difference between the inlet and outlet of the device. The softening treatment effect is monitored by the tubular membrane intelligent filtration device's water pipe meter. The monitoring data is collected and transmitted to the intelligent control module to calibrate the amount of dosing in the system's softening stage. At the same time, sulfuric acid is added to the water pipe through the acid dosing device to adjust the pH of the produced water to meet reuse requirements. The sludge at the bottom of the second and second slow flocculation and concentrating tanks is discharged for treatment. The entire system continuously monitors the water quality of the incoming water and the system's produced water, matches the softening and dosing settings, detects the softening effect of the dosing, continuously accumulates data, and continuously adapts the dosing.
