Lift pump house and post-ozone contact pool combined structure

Abstract

The invention discloses a lift pump house and post-ozone contact pool combined structure. The lift pump house and post-ozone contact pool combined structure is characterized in that a lift pump house suction well which is connected with a water inlet pipe is arranged on the lower layer of a lift pump house, a water outlet confluence channel is arranged on the upper layer of the lift pump house, a lift pump is arranged between the upper layer and the lower layer of the lift pump house, the water outlet confluence channel is communicated with a post-ozone contact pool, an ozone pool is communicated with a water outlet well, and the water outlet well is connected with a water outlet pipe. An ozone generator room is constructed on the upper portion of the post-ozone contact pool in a combined mode, an ozone generator is arranged in the ozone generator room, and the ozone generator is connected with an ozone gas distributing pipe in the contact pool. According to the lift pump house and post-ozone contact pool combined structure, a plurality of structures are compactly and reasonably combined, a water outlet pipeline system of the lift pump house is omitted, an ozone conveying system and an electric transmission line system are simplified, engineering occupied land and investment are saved, and operation fees are reduced; and simultaneously, the storage capacity of the lift pump house suction well is increased, frequent opening times of the water pump are reduced, production management is convenient, and operation safety is guaranteed.

Description

Technical field [0001] The invention relates to a structure in the advanced treatment process of ozone activated carbon in a water supply plant, and specifically relates to a combination of a lifting pump house and a rear ozone contact pool, an ozone generator (containing ozone exhaust gas destruction device) and a configuration in the advanced treatment process The electric room is combined into an integrated lifting pump room and rear ozone contact pool combined structure. Background technique [0002] At present, most advanced treatment processes in water plants use post-ozone biological activated carbon processes, and it is most common to add ozone activated carbon after existing conventional treatment processes. Due to the limitation of the hydraulic elevation of the water plant, the water after conventional sand filter processing often needs to increase the water level before entering the post-ozone activated carbon process. The current conventional practice is to lift the ...

AI Technical Summary

Problems solved by technology

Due to the limitation of the hydraulic elevation of the water plant, it is often necessary to increase the water level once after the water after the conventional sand filter enters the post-ozone activated carbon process. Structures such as electric rooms are set up separately. This conventional method has defects such as high investment, large land occupation, multiple equipment, and high operation and maintenance costs. The biggest defect is that the pump room needs to be equipped with a water outlet pipeline, and its water head loss accounts for about half of the pump lift. , high energy consumption, and pipelines and equipment are easily corroded by ozone

The post-ozone activated carbon process is added on the basis of the original conventional process of the waterworks. The available land in the waterworks is very tight. The lifting pump room, the post-ozone contact pool, the ozone generator room and the power distribution room are set up separately. The land utilization rate is not high. In order to arrange other structures, the design must sacrifice the storage volume of the pump room, which will bring great trouble to the operation of the water plant in the future and is not conducive to the safe operation of the water plant.

The actual operation of the current water plant using the conventional ozone activated carbon advanced treatment process has exposed these unfavorable problems
