Integrated automatic flow adjusting and intercepting well equipment and intercepting process thereof

Abstract

The invention discloses an integrated automatic flow regulating and intercepting well equipment, which includes an equipment box, the equipment box is made of glass fiber reinforced plastic, and the inside of the equipment box is divided into four parts by cross-shaped glass fiber reinforced plastic partitions, and the four parts are divided into four parts according to Confluent sewage wells, overflow sewage wells, anti-sewage backflow wells and valve wells are arranged clockwise. The integrated automatic flow regulating and intercepting well equipment of the present invention adopts structural equipment, and introduces a swirl flow limiting valve and a duckbill valve at the same time, avoiding the long construction period of traditional intercepting wells, the difficulty of accurately controlling the amount of intercepted sewage, and the inability to prevent backflow Defects. The invention also discloses a flow closure process of the integrated automatic flow regulation and closure well equipment.

Description

technical field [0001] The invention relates to a combined sewage interception device, in particular to an integrated automatic flow regulation and interception well device and its interception process. Background technique [0002] Many old cities at home and abroad have almost always adopted combined drainage systems in the past. This system is a system that mixes domestic sewage, industrial wastewater and rainwater in the same pipe. The earliest combined drainage system was to discharge the mixed sewage into the nearby water body without treatment. Since the sewage was discharged without harmless treatment, the receiving water body was seriously polluted. In order to solve this problem, if all urban domestic sewage, industrial wastewater and rainwater are sent to sewage treatment plants for treatment, it is necessary to lay large-diameter drainage pipe networks and build large-scale sewage treatment plants, which will increase construction and operating costs , in addit...
