Compact gravity type uniform water distribution device and water distribution method of underground sewage plant

Abstract

The invention provides a compact gravity type uniform water distribution device and water distribution method for an underground sewage plant. A water distribution tank is arranged on the side wall of a water distribution channel and connected with a water outlet pipe; a water inlet pipe is arranged at the front end of the water distribution channel, and an overflow weir is arranged at the rear end and connected with an overflow pipe; an ultrasonic liquid level instrument is further arranged in the water distribution channel, and the bottom of the water distribution channel is connected with an emptying pipe through an emptying electric valve; and the ultrasonic liquid level instrument controls the emptying electric valve in a linkage manner. According to the invention, two thirds of space can be saved; the water distribution tank is of a light structure, the height can be properly adjusted according to the condition of a water inlet of equipment, and on-site installation and actual construction are convenient; and the device is easy to implement, low in cost, good in effect, easy and convenient to operate and maintain and suitable for being popularized and used in underground sewage plants.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a compact gravity-type uniform water distribution device for an underground sewage plant and a water distribution method thereof. Background technique [0002] From a global perspective, underground sewage treatment plants started in developed countries in Europe. In recent years, with the acceleration of my country's urbanization process and the continuous improvement of environmental requirements, underground sewage treatment plants have ushered in new opportunities for development in my country and have developed rapidly. In the past ten years, newly-built sewage plants in economically developed areas mostly use underground structures . At present, domestic underground sewage treatment plants mainly have three layout forms: semi-underground double-layer covering, fully underground double-layer covering, and fully underground single-layer covering...

AI Technical Summary

Problems solved by technology

[0007] 1. Most of the underground sewage plants are designed with two or three layers of cover, and the water distribution system is located on the second or third layer. The heavy weight of the civil engineering channel for water distribution requires more columns to support, which will greatly increase the civil engineering cost;

[0008] 2. Concrete structure is used for water distribution in civil engineering channels, which requires a large design space, which is not conducive to the actual use of underground sewage plants;

[0009] 3. According to the calculation at the early stage of design, the water distribution of civil engineering channels cannot change the water distribution volume and situation after completion, and cannot be well connected with the back-end treatment process structures.

[0010] 4. It is inconvenient to clean up the silt at the bottom of the water distribution channel of the civil engineering channel
