Abstract

The invention discloses a reaction system applied to urban initial rainwater and black and odorous water treatment, which comprises a reaction tank, a submersible stirrer and a flocculant adding device, the submersible stirrer is arranged in the reaction tank, and the flocculant adding device comprises a dilution tank, a first connecting pipe, a second connecting pipe, a chemical pump and a dispensing pipe. The dilution box comprises a box body, a feeding hopper, stirring blades and a stirring motor, the stirring blades are arranged in the box body, the stirring motor is connected with the stirring blades, the feeding hopper is arranged at the top of the box body and communicated with the interior of the box body, a connecting port is formed in the box body, the first connecting pipe is connected with the connecting port and the pesticide pump, and the second connecting pipe is connected with the pesticide pump and the dispensing pipe. The dispensing pipe is horizontally arranged above the reaction tank, and a plurality of medicine outlets are formed in the bottom of the dispensing pipe. Compared with the prior art, the flocculating agent can be added.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reaction system applied to the treatment of urban initial rainwater and black and odorous water bodies. Background technique [0002] Initial rain, as the name suggests, refers to the rain at the beginning of the rain. Usually, the amount of rainfall in the initial period of 15-30 minutes of rainfall, or the amount of rainfall with a thickness of 20-30 mm in the initial period of rainfall, is defined as initial rainfall. In the early stage of the rainfall, the rainwater dissolves a large amount of polluting gases such as acid gas, automobile exhaust, factory exhaust gas, etc. in the air. After landing on the ground, due to the scouring of the roof and asphalt concrete roads, the initial rainwater contains a large amount of pollutants, such as SS (Suspended solids), COD (Chemical Oxygen Demand), BOD5 (Biochemical Oxygen Demand) and other pollutant indicators are relati...
