Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water distribution well integrating filtration, overflow, mud discharge and emptying. Background Art

[0002] In modern society, people's lives and production will generate a large amount of wastewater. These wastewaters cannot be directly discharged into natural water sources and must be treated before they can be discharged. Wastewater often needs to be distributed during the treatment process. The so-called water distribution is the process of distributing the total incoming water of the previous unit to the subsequent two or more groups of units as needed. As a flow distribution structure, the water distribution well is one of the important structures and equipment in the field of sewage treatment. It is widely used in urban sewage treatment plants, water treatment plants and other places where flow distribution is required. Its main function is to distribute raw water, especially in water treatment plants. Almost every water plant needs to be equipped with a water distribution well for even flow distribution.

[0003] In order to ensure the reliability of the municipal water supply pretreatment system and the convenience of building maintenance, multiple groups of structures in parallel are usually set up so that some structures can be inspected in turn without stopping production. This requires the water distribution well to reasonably distribute the water to the subsequent structures. If the water cannot be reasonably distributed, some structures will often operate at full load or even overload, while some structures will be underloaded, and all structures cannot be in the optimal operating state and play their full role. In order to achieve the requirement of water distribution on demand for water purification structures, the design of water distribution wells is particularly important. Some water distribution wells have also been reported in public literature, such as:

[0004] 1. Chinese Patent: A water distribution well system with flow rate distribution on demand, Application No.: 201720514407.5, Application Date: 2017.05.10, Abstract: A water distribution well system with flow rate distribution on demand, comprising a water distribution well, wherein the lower part of the water distribution well is a water distribution well shaft, a flow stabilizing grid is arranged on the top of the water distribution well shaft, and water in the water distribution well shaft can enter the upper well cavity of the water distribution well through the flow stabilizing grid; a water distribution trough is arranged on the upper part of the water distribution well, an adjusting weir gate is arranged between the water distribution trough and the upper well cavity of the water distribution well, and a downward electric hoist connected to the adjusting weir gate is also arranged, and the height of the weir gate is adjusted by the downward electric hoist, so as to control the amount of water overflowing into the water distribution trough; a water distribution well outlet pipeline is arranged at the bottom of the water distribution trough, and one end of the water distribution well outlet pipeline is connected to the water distribution trough.

[0005] 2. Chinese Patent: Water Distribution Well and Water Distribution System, Application Number: 202321445817.0, Application Date: 2023.06.08, Abstract: The present disclosure provides a water distribution well and a water distribution system in an embodiment. The water distribution well includes a civil engineering part and a water distribution part. The civil engineering part includes a bottom plate, an outer wall, a plurality of water distribution weirs and a plurality of partition walls arranged at intervals. The outer wall, two adjacent partition walls and the water distribution weir located between the two partition walls together form an outlet channel. The side of the water distribution weir away from the outlet channel includes an inlet channel, and the inlet channel is connected to the outlet channel through the water distribution weir. The water distribution part includes a plurality of weir plates, and the plurality of weir plates are arranged on the plurality of water distribution weirs. The height of the weir plates can be adjusted to adjust the amount of water passing through the outlet channel. Through the scheme disclosed in the present disclosure, the total incoming water of the inlet channel can be distributed to the plurality of outlet channels in unequal amounts, and the flow rate of each outlet channel can be adjusted.

[0006] Through applied research, it is found that the above-mentioned and existing water distribution wells mainly consider the use of overflow manual adjustment weirs to distribute the flow, which is difficult to achieve precise control. In addition, the water distribution wells do not have the functions of filtering, overflowing and sludge discharge at the same time. If the water distribution well is not equipped with an overflow port, when the raw water exceeds the design value, the subsequent flocculation sedimentation tank and filter tank will be overloaded, and the final treated clean water will overflow from the clear water tank. This will affect the normal and stable operation of the water plant, and waste the dosage and energy consumption, and fail to achieve the purpose of energy saving and emission reduction, and increase the treatment cost of the water plant; some water distribution wells are not equipped with filtering facilities. Generally, a coarse grid is set in the water intake pump room or a fine grid is set behind the water distribution well. The front grid can only intercept larger garbage, and the smaller ones will still enter the water plant, resulting in blockage of the flocculation sedimentation tank and filter tank; and the grid is set at the rear end, the investment is relatively high and more complicated. Therefore, it is necessary to redesign a water distribution well that integrates water distribution, filtration, overflow, and sludge discharge. Summary of the invention

[0007] The purpose of the utility model is to provide a water distribution well integrating filtration, overflow, sludge discharge and emptying. The water distribution well integrating filtration, overflow, sludge discharge and emptying can accurately and automatically adjust the water distribution volume of each part of the water distribution well, reduce labor costs and increase adjustment accuracy; avoid overload operation of subsequent structures and increase unnecessary processing costs and energy consumption; effectively reduce the probability of clogging of the inclined tube sedimentation tank and filter tank of subsequent processing structures, and facilitate maintenance and management.

When the sediment in the mud bucket reaches a certain amount, the mud discharge valve on the mud discharge pipe is opened to discharge it. When the water distribution well needs to be repaired, the mud discharge valve is also opened to completely empty the water distribution well to facilitate maintenance personnel; when the raw water volume exceeds the design value, it overflows out of the main inlet shaft through the overflow port and enters the overflow channel.
