Problems solved by technology

[0008] If according to the traditional method, the rainwater pipes containing the waste water are directly sent to the sewage pipe network and treatment system, on the one hand, the existing residential area is tight and the renovation work is difficult. After the renovation, if there is a large amount of rainwater, it will give urban sewage The treatment plant brings a large load impact, which affects the normal operation of the sewage treatment plant
[0009] Under the current technical conditions, the construction cost and operating cost of the equipment for treating impurities in rainwater will increase inevitably. The existing traditional process and treatment method have the disadvantages of long process flow, complicated control, large land occupation and high treatment cost.

Abstract

The invention discloses a flow-discarding deep circulation purification device for rainwater and its purification process, which is composed of a fixed leg, a rainwater purification body chamber, an air intake pipe, an air outlet pipe, a circulation return pipe, a rainwater input system, a drainage pipe, and a control center. . The upper surface of the fixed leg is provided with a rainwater purification body warehouse, the air intake pipe and the air outlet pipe are arranged on the upper surface of the rainwater purification body warehouse and communicate with the interior of the rainwater purification body warehouse, and the air inlet pipe and the air outlet pipe The rainwater input system is located on one side of the fixed leg and communicates with the rainwater purification body compartment through the circulation return pipe. The number of the drainage pipes is 2 groups, and the drainage pipes are symmetrically arranged on the outer walls of both sides below the rainwater purification body compartment. The control center is located at the bottom of the fixed outriggers. The waste flow type rainwater deep circulation purification device described in the present invention has a novel and reasonable structure, is convenient to operate, has high efficiency in removing impurities in rainwater, and is suitable for purification treatment of different kinds of impurities in rainwater.

Description

technical field [0001] The invention belongs to the field of rainwater purification devices, and in particular relates to a flow-discarding deep circulation purification device for rainwater and a purification process thereof. Background technique [0002] With the increasing rate of urbanization and the hardening of roads, it is difficult for rainwater to infiltrate, resulting in frequent urban waterlogging. The government has proposed to vigorously build the concept of "sponge city" with natural accumulation, natural infiltration and natural purification. The Ministry of Housing and Urban-Rural Development issued the "Technical Guidelines for Sponge City Construction". Under the vigorous call of the country, the construction of sponge cities has gradually been recognized and familiarized by everyone. The construction of a sponge city is to reduce the runoff of rainwater and reduce the pressure of drainage pipes through "stagnation, storage and use", thereby reducing the p...
