Abstract

The invention relates to a rainwater runoff pollution sewage interception facility and a sewage interception operation method. An integrated facility main body is in a barrel shape. Two sides of the upper part of the facility main body are provided with a water inlet pipe and a water outlet pipe. The water inlet pipe has an inclination angle and is inserted in the facility main body, and is tangent with the peripheral body of the facility main body and is inserted into an inner wall. A supporting frame in the facility main body is provided with a guide cylinder. Rainwater forms an eddy state between the inner wall of the facility main body and the guide cylinder, to generate centrifugal force. Foreign matters in rainwater fall into a sediment collecting region from a lower ventage of a guide plate, and the foreign matters are discharged after a slag-drip opening is opened. The facility is simple in structure, good in reliability, and simple in installation and maintenance. Improvement on an original initial rainwater sewage interception device improves interception and processing efficiency of rainwater runoff pollution, and a filter layer in a water outlet pipe can fully filter surplus pollutants, and the improved facility main body still keeps integrated. The facility is convenient in installation and overhaul, and just needs regular checking and dredging and pollution discharge.

Description

technical field [0001] The invention relates to an improved rainwater runoff pollution interception device, in particular to a rainwater runoff pollution interception facility and a sewage interception operation method. Background technique [0002] China is one of the most water-scarce countries in the world. my country is rich in rainwater resources, and the collection and utilization of rainwater has become particularly important. Due to the serious pollution of the initial rainwater, it cannot be directly discharged into the receiving water body. At present, most of the initial rainwater interception devices can only simply intercept suspended solids, oil pollution and other pollutants in the initial rainwater, and the treatment efficiency is not high, especially for pollutants with small particle sizes, and the initial rainwater carries a large amount of air. Pollutants in and on the ground. Contents of the invention [0003] The main purpose of the present inventio...
