Description

Technical Field

[0001] The invention relates to the technical field of polyether production wastewater treatment, in particular to a multi-stage wastewater treatment device for polyether production. Background Art

[0002] The process of treating wastewater from polyether production is as follows: the wastewater is first collected in a receiving and regulating tank for preliminary mixing and adjustment to balance the flow and adjust the pH value; then, the wastewater flows out to a grease trap to remove floating oil and some heavy oil; the treated wastewater enters a coagulation sedimentation tank, where suspended matter and some colloidal substances are precipitated after the addition of coagulants; the wastewater continues to flow to the flotation separation equipment to further remove emulsified oil and suspended solids; then, the wastewater flows into a hydrolysis acidification tank to improve the biodegradability of refractory organic matter; then, the wastewater enters a biological filter tank to degrade organic pollutants using microorganisms on the filter media; then, the wastewater flows into an activated sludge aeration tank, where organic pollutants are further degraded by microorganisms in the activated sludge; the wastewater after biological treatment enters an advanced oxidation treatment unit, such as an ozone oxidation tower, an ultraviolet light oxidation device or a Fenton oxidation tank, to degrade refractory organic pollutants; finally, the wastewater is adsorbed by activated carbon to remove residual organic matter and color. However, after being used for a period of time, activated carbon needs to be replaced due to its reduced adsorption capacity. In the prior art, the replacement process of activated carbon is often complicated and must be carried out by stopping the machine, which not only interrupts the continuity of wastewater treatment and reduces the treatment efficiency. In addition, in the prior art, wastewater usually flows directly out of the water pipe and contacts the activated carbon. The impact force of the water flow is too large, which may cause the displacement of activated carbon particles and cause uneven distribution of the activated carbon layer. This unevenness may cause local voids or accumulation in the activated carbon layer, thereby affecting the adsorption effect and the overall performance of wastewater treatment.

[0036] In actual use, in order to ensure the activated carbon adsorption effect, the wastewater needs to undergo pretreatment, primary treatment and intermediate treatment before entering the activated carbon adsorption unit, which mainly includes the steps of removing suspended matter, adjusting water quality, coagulation and flocculation, biodegradation and oxidation. The wastewater after the above treatment is transported to the water inlet pipe 5 by a water pump, and the wastewater enters the diversion pipe 2, and then flows out from the two water diversion connecting pipes 3.

When the blocking cone 8 drives the water receiving fixed plate 91 to move downward through the fixed connecting rod 11, the water diversion inclined plate 93 is driven to approach the activated carbon inside the adsorption sliding box 4. The wastewater can flow out through the unblocked water diversion connecting pipe 3, and the outflowing wastewater falls on the blocking cone 8 below. The wastewater is then dispersed on the water receiving fixed plate 91, and then flows out from multiple strip outlet pipes 92, passes through multiple water guide grooves 94 on the two water diversion inclined plates 93, and finally drips from multiple drip short pipes 95, avoiding the impact of water flow impact on the activated carbon. When the activated carbon is saturated, the fixed motor 75 is controlled to reverse, which can drive the middle gear 78 to rotate, and the middle gear 78 can drive the two T-shaped tooth plates 72 to move, and then drive the blocking cone 8 in the blocked state to move downward, and the blocking cone 8 at the bottom moves upward to block the water diversion connecting pipe 3 above it, so as to facilitate the replacement of the activated carbon in the adsorption sliding box 4.When the blocking cone 8 moves upward to block the water diversion connecting pipe 3, the blocking cone 8 drives the water receiving fixed plate 91 to move upward, and the water receiving fixed plate 91 drives the fixed drive block 96 to separate from the supporting sliding plate 97, and drives the supporting sliding plate 97 to move upward under the elastic action of the first return spring 99, and releases the restriction of the supporting sliding plate 97 on the moving connecting block 913, and drives the moving connecting block 913 to move upward under the elastic action of the second return spring 914, and the moving connecting block 913 drives the two first sliding blocks 911 to approach each other through the two first push plates 912, and the first sliding block 911 drives the L-shaped plug plate 916 to move out of the limiting slot 918 through the second push plate 915, and releases the restriction of the limiting slot 918 on the L-shaped plug plate 916, so that the adsorption sliding box 4 can be moved out of the sliding installation slot 12, so as to facilitate the replacement of the activated carbon in the adsorption sliding box 4.
