Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a comprehensive utilization device and utilization method for white pulp wastewater treatment. Background Art

[0002] White pulp wastewater is a special polluting wastewater generated in the papermaking process, mainly originating from the bleaching and washing stages in the pulp and paper making process. It contains a large amount of organic matter and inorganic salt components and cannot be directly discharged, so it needs to be treated.

[0003] In the prior art, for the treatment of white pulp wastewater, large particulate impurities need to be removed first through a grille, and then small particulate matter in the white pulp wastewater is removed by air flotation and sedimentation methods to obtain clear liquid. The organic matter in the clear liquid is degraded into inorganic matter through subsequent biochemical treatment methods, and then wastewater meeting the discharge standards is obtained through subsequent secondary sedimentation, filtration and other steps for subsequent reuse. In the sedimentation step, several kinds of mixed precipitants need to be added thereto. There are real-time changes in the flow rate of the slurry to be precipitated and the particulate concentration, which will cause an error between the delivery amount of the precipitant and the delivery amount of the slurry. When the precipitant is less, the precipitation reaction is likely to be incomplete. When the precipitant is more, more inorganic salts in the slurry need to be removed, and it is difficult to realize the intelligent control of the sedimentation tank. Summary of the Invention

[0038] Embodiment 2: A detection and control module is provided in the treatment box body 1. The detection and control module includes a flow rate detection and processing unit and a concentration detection and processing unit. The flow rate detection and processing unit is used to obtain the real - time flow rate data f of the flow rate sensor at the electric control valve 6 and the standard flow rate data entering the treatment box body 1 and process and analyze them. According to the analysis results, control the rotating grid plate 201 and the scraper 202 to achieve automatic adjustment of grid plate filtration to maintain a stable filtration effect; the concentration detection and processing unit is used to obtain the real - time particulate matter concentration data c1 of the first concentration sensor in the storage liquid tank 113 and the real - time particulate matter concentration data c2 of the second concentration sensor at the gate valve 3. According to the analysis results, control the ratio of the feeding pipe 109 and the rotation speed of the motor 110 to achieve automatic adjustment of the operation of the sedimentation tank 101 to maintain a stable treatment effect of the slurry;

[0039] The processing method of the flow rate detection and processing unit includes the following steps:

[0040] Step 1: Calculate the ratio parameter F by calculating the ratio of the flow rate data f to the standard flow rate data, and perform data analysis on the ratio parameter F. If the ratio parameter F is within the standard flow rate range, generate a continuous detection instruction; if the ratio parameter F is less than the minimum value of the standard range, generate a detection control instruction;

[0041] Step 2: According to the continuous detection instruction, maintain the operation rates of the first control cylinder 4 and the second cylinder 5, respectively, so that the rotating grid plate 201 operates at the standard rate and the scraper 202 operates at the standard rate; according to the detection control instruction and the ratio parameter F, adjust the cleaning rate of the rotating grid plate 201, and trace the adjusted ratio parameter F until the adjusted F is within the standard flow rate range, then generate a detection recovery instruction, and adjust the cleaning rate of the rotating grid plate 201 back to the standard rate according to the detection recovery instruction; the adjusted cleaning rate is obtained by multiplying the standard rate by the ratio parameter F;

[0042] By analyzing the ratio parameter F to regulate the operating rate of the filtering component 2, the flow rate output from the liquid storage tank 113 can be regulated in real time, improving the autonomous monitoring and control effect of the filtering component 2;

[0043] The processing method of the concentration detection and processing unit includes the following steps:

[0044] Step 1: Detect and obtain the first real-time particulate matter concentration data c1 of the liquid storage tank 113, detect and obtain the second real-time particulate matter concentration data c2 at the gate valve 3, and analyze the obtained data;

[0045] Step 2: Calculate the concentration monitoring value C by passing the obtained first real-time particulate matter concentration data c1 and the second real-time particulate matter concentration data c2 through the formula ; cb is the standard concentration error. Perform data analysis on the concentration monitoring value. If the concentration monitoring value is greater than 1, it is determined that the sedimentation tank 101 operates abnormally and a concentration anomaly label is generated; otherwise, it is determined that the sedimentation tank 101 operates normally and a concentration normal label is generated;

[0046] Step 3: Maintain the existing operating speed of the motor 110 and the conveying amount of the feeding pipe 109 in the existing sedimentation tank 101 according to the concentration normal label;

[0047] And, obtain the preset adjusted speed of the motor 110 in the sedimentation tank 101 according to the concentration anomaly label, control the motor 110 to operate at the adjusted speed, and perform retrospective analysis on the concentration monitoring value after the speed adjustment of the motor 110. If the adjusted concentration monitoring value is greater than 1, a concentration adjustment invalid label is generated; if the adjusted concentration monitoring value is not greater than 1, a concentration adjustment effective label is generated;

[0048] Obtain the preset adjusted conveying amount of the feeding pipe 109 according to the concentration adjustment invalid label, control the feeding pipe 109 to convey through the adjusted conveying amount and perform secondary retrospective analysis on its adjusted concentration monitoring value. If the concentration monitoring value after the secondary adjustment is greater than 1, a secondary concentration adjustment invalid label is generated and the adjusted conveying amount is increased until the concentration monitoring value after the secondary adjustment is not greater than 1;

[0049] If the concentration monitoring value after the secondary adjustment is not greater than 1, a secondary concentration adjustment effective label is generated;

[0050] Set the adjusted speed of the motor 110 to the median speed 1.5 between the standard speed 1 and the limit speed 2;

[0051] When the adjustment of the rotational speed of the motor 110 is ineffective, further adjust the conveying volume of the feeding pipe 109, and conduct a retrospective analysis on the conveying of the adjusted feeding pipe 109. Set the standard conveying volume to 1. If a secondary concentration adjustment invalid label is generated, the conveying volume can be adjusted to 1.2. If the secondary concentration adjustment invalid label continues to be generated, the conveying volume can be gradually increased by 0.1 times. By gradually increasing the conveying volume of the precipitant conveyed by the feeding pipe 109 until a secondary concentration adjustment valid label is generated;

[0052] By monitoring the real-time particulate matter concentration c1 in the liquid storage tank 113 and the real-time particulate matter concentration c2 at the gate valve 3, analyzing and calculating the concentration monitoring value, and judging the state of the sedimentation tank 101 through the concentration monitoring value, controlling the operation of the feeding pipe 109 and the motor 110 through the judged state, the treatment effect of the sedimentation tank 101 on wastewater is improved, and the intelligent operation of the sedimentation tank 101 is realized.

Check the treatment box (1): check the gate valve (3) to make sure it is in a closed state, check the electric control valve (6) to make sure it is in an open state, and check the filter component (2) to make sure it is in an initial state; S2, introducing the slurry to be treated; opening the electric control valve (6), introducing the slurry to be treated into the sedimentation tank (101), making the liquid level at the liquid level controlled by the water level pipe (112), closing the electric control valve (6), and filling the liquid storage tank (113) with a certain amount of slurry; S3, pre-start: adding a precipitant in an amount suitable for the slurry in the sedimentation tank (101) through the feeding pipe (109), and precipitating the particles in the slurry through the sedimentation component. After the precipitation reaction is completed, the gate valve (3) is opened to gradually introduce the slurry into the flotation tank (102) until the liquid level in the flotation tank (102) is equal to the liquid level in the sedimentation tank (101); S4, start the treatment component: open the electric control valve (6), control the operating speed of the filter component (2), maintain the filtering effect of the rotating grid plate (201) so that the flow rates of the control storage tank (113) and the feed pipe (103) are equal, start the flotation tank (102), and add a precipitant in a proportion to the amount of precipitant entering the sedimentation tank (101) per unit time until the liquid levels of the sedimentation tank (101) and the flotation tank (102) are at the water level pipe (112), and continue to treat the slurry.
