Description
Technical Field
[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an industrial wastewater resource regeneration treatment system and a process thereof. Background Art
[0002] In the process of industrial production, a large amount of water resources are often needed to clean and cool equipment or products, which leads to the mixing of heavy metals, organic matter, acid-base substances, oil and other harmful substances in the used water. Since these processes use a large amount of water, the discharge after treatment will still have an adverse impact on the environment, and re-extracting clean water for the above treatment process will waste too much water resources. Therefore, an industrial wastewater resource regeneration treatment system is needed to regenerate the wastewater, so that the factory can reuse the water.
[0003] After searching, the prior art publication number is CN118005220A, which is an industrial wastewater resource regeneration system and process. The invention automatically puts the precipitation agent into the wastewater by setting an automatic medicine delivery component, and stirs and aerates the wastewater with the precipitation agent through a high-mix aeration component. However, the bubbles generated during aeration may adhere to some small-volume sediments or some suspended solids that are not combined with the precipitation agent for precipitation, causing these sediments and suspended solids to float and cover the water surface, blocking the medicine delivered by the automatic medicine delivery component, so that some medicines cannot enter the wastewater, resulting in a decrease in the wastewater treatment rate;
[0004] After searching, the prior art publication number is CN118063050A, which is a device for treating industrial high-salt wastewater. The device can clean and collect water-insoluble impurities on the surface of the filter plate while filtering the high-salt wastewater through the filter component; at the same time, flocculants and coagulants are added to the wastewater treated by the filter component, and aeration treatment is carried out, and then the scum floating on the water surface during aeration is cleaned by the impurity removal component; but the scraping component in the impurity removal component cannot be adjusted according to the liquid level of the wastewater, so when the water level is too low or too high, the scraping component is likely to have residue when cleaning the scum. Summary of the invention
[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an industrial wastewater resource regeneration treatment system and process thereof. The stirring device in the present invention can expand the range of aeration of the wastewater while stirring and mixing the wastewater and the reagent, thereby increasing the rate at which the device treats the wastewater; at the same time, the scum collecting device cooperates with the residue collecting device to clean the scum to prevent scum from remaining.
[0006] In order to achieve the above object, the technical solution adopted by the present invention is:
[0007] An industrial wastewater resource regeneration treatment system and process thereof, the specific process steps are as follows:
[0008] 1) Pretreatment: Filter out the larger particle impurities in the wastewater through a screen with a pore size of 5-20mm, then add a neutralizing agent to the wastewater at a dosage of 0.3-2.2g / L to adjust the pH value of the wastewater to between 6.7-8.5;
[0009] 2) Sedimentation and filtration: The sediment and other small particles carried by the wastewater are removed by sedimentation for 1.5-3 hours. The surface load rate of the sedimentation tank is 1.5-2.7m³ / (m²·h). Then, the suspended matter and dissolved matter in the wastewater are further removed by the combination of activated carbon and sand filter. The dosage of activated carbon is 0.8-1.7 g / L, and the filtration rate of the sand filter is 8-15 m / h.
[0010] 3) Aeration treatment: The wastewater treated by step 1) and step 2) is transported to the aeration tank in the industrial wastewater resource regeneration treatment system, and then the coagulant and flocculant are added to the wastewater and stay in the aeration tank for 6-9 hours, wherein the dosage of the coagulant and flocculant is 20-60 mg / L and 0.7-2.3 mg / L respectively, and the aerator is turned on to aerate the wastewater with an air intake of 20-42 L / h, and the dissolved oxygen concentration in the aeration tank is maintained at 2-4 mg / L; then the stirring device controls the sliding seat I and the sliding seat II to slide reciprocatingly along the support plate I and the support plate II through the cooperation of the motor IV and the screw II, so that the stirring mechanism and the aeration mechanism move with the sliding seat I and the sliding seat II, and the wastewater is reciprocatedly aerated while being stirred reciprocally at a speed of 25-60 rpm for 35-50 minutes;

[0012] When the displacement mechanism drives the skimmer to move, the skimmer will be separated from the water surface, causing the scum to lose its obstruction and start to float around; at this time, the residue collection device controls the rotating box to rotate toward the collection box, thereby scraping up some of the scum scattered on the water surface, and at the same time, the scum scraped up by the rotating box is scraped into the rotating box through the material blocking mechanism; and while the rotating box rotates, the waste water can be guided to the collection box, so that some of the scum enters the collection box, and then the sewage pump pumps the scum in the collection box and the rotating box into the storage box through the transport pipe and telescopic pipes I and II;
[0013] 4) Post-treatment: After step 3), the treated wastewater enters the water storage tank through the outlet I, and the sludge settled at the bottom of the aeration tank is cleaned out through the sewage outlet; then the water entering the water storage tank is disinfected, and the dosage of the disinfectant is 2-7 mg / L, and it is tested by the detection equipment.
