Abstract

The invention provides an initial rainwater pollutant interception facility and an interception operation method. The whole main body of the facility is in 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 is inclined and is inserted in the facility main body and is connected with a peripheral body tangent insertion inner wall of the facility main body. A supporting frame in the facility main body is provided with a diversion cylinder. Rainwater forms an eddy state between a porous inner wall main body and the diversion cylinder, to generate centrifugal force. Foreign matters in rainwater fall in a sediment collection region from a lower ventage of a guide plate, and are discharged by opening a discharge hole. Pollutants intercepted in the porous inner wall are eliminated through microbial decomposition. The facility is simple in structure, good in reliability, and simple in installation and maintenance, and improves an original initial rainwater pollutant interception device, and interception and treatment efficiency on rainwater runoff pollutants is improved. The pollutants intercepted in the porous inner wall are fully decomposed and treated by microorganism, and a filter layer in the water outlet pipe can fully filter rest pollutants. The improved facility main body still maintains to be integrated, and installation and overhaul are convenient, and just regular checking and desilting and pollution discharge are needed.

Description

technical field [0001] The invention relates to an improved initial rainwater sewage interception device, in particular to an initial rainwater sewage 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 invention i...
