Description

First heavy processing system for sewage

Technical field

The utility model belongs to technical field, more particularly, to a kind of first heavy processing system for sewage.

Background technology

The first heavy processing system of sewage is currently used for, in the running of reality, following weak point be present：Sewage with Coagulated agent mixing, which need to be set, mixes pond, space-consuming；Sludge interface in pond is not required so that precipitating sludge is formed Embryonic particle is smaller, easy water outlet band mud, to reduce water outlet band mud phenomenon, certainly will increase coagulated agent dosage, cause to handle Cost increase.

Utility model content

The utility model is for overcome the deficiencies in the prior art, there is provided a kind of processing cost is low, and sedimentation effect is good to be used for The first heavy processing system of sewage.

To achieve these goals, the utility model uses following technical scheme：A kind of first heavy processing system for sewage System, including sedimentation basin, the cloth hydroecium in the middle part of sedimentation basin, the water inlet pipe for being communicated in the cloth hydroecium, radome fairing, located at cloth hydroecium On delivery port, scrape mud part, the storage mud chamber positioned at sedimentation basin bottom, be communicated in the discharge pipeline of the storage mud chamber, positioned at sedimentation basin Top water leg and the outlet pipe being connected with the water leg;The radome fairing bottom is set for opening, the radome fairing lower openings It is less than the height h2 of sludge in sedimentation basin with the distance h1 of sedimentation basin bottom surface；The delivery port and the distance h3 of sedimentation basin bottom surface are big In the height h2 of sludge in sedimentation basin.The height h2 of sludge is controlled to be higher than radome fairing lower openings and sedimentation basin in the utility model The distance h1 of bottom surface, the circulation upwards again after sludge blanket in advance after sewage is flowed out by the opening of radome fairing bottom so that warp The little particle sludge or impurity crossed after flocculation are deposited in sludge blanket in the case where the filtering of sludge blanket catches double action with net, will not As sewage discharges, sludgd deposition rate is improved, water outlet band mud rate is reduced, reduces the use of coagulant, reduce cost.

Further, the sedimentation basin connection one is used for the sludge interface instrument for detecting the height h2 of sludge in sedimentation basin；Can Mud height in detection sedimentation basin in real time, when sludge is too high, worker can carry out appropriate spoil disposal operation to sedimentation basin, prevent Mud height is too high, while sludge is maintained in h2 height；Preferably, h2 for 3/4 of the depth of water in sedimentation basin.

Further, a pipe-line mixer is connected on the water inlet pipe, a chemical feed pipe is connected on the pipe-line mixer;It is logical Cross chemical feed pipe to add flocculant in pipe-line mixer, flocculated to entering the sewage in pipe-line mixer.

Preferably, the chemical feed pipe encloses outside the pipe-line mixer in the shape of a spiral, pipe-line mixer side wall be provided with The dosing mouth that the chemical feed pipe is connected；So that flocculant can be sprayed into pipe-line mixer by the different angle of pipe-line mixer Interior, the mixing with sewage is more abundant, and flocculating effect is more preferable.

Further, the sedimentation basin bottom surface is pyramidal structure, and the mud part of scraping is included on sedimentation basin bottom surface Cleaning shoe, the drive link being connected with the cleaning shoe, the drive shaft that is connected with the drive link and for driving the drive shaft turns Actuator；Drive shaft rotates under the drive of actuator, by drive link drive to cleaning shoe drive cleaning shoe using drive shaft as Center is rotated, and cleaning shoe loosens the sludge scraping on sedimentation basin bottom surface during rotating；Because sedimentation basin bottom surface is cone Shape structure so that the face contacted with cleaning shoe is inclined-plane, is easy to sludge to be slipped into automatically and stores mud intracavitary.

Or it is further, the drive link is L-shaped structure；Drive shaft is allowd to be arranged on the position of sedimentation basin central part Put, ensure that cleaning shoe is rotated around sedimentation basin center, it is good to scrape mud effect.

In summary, the utility model is by controlling the height h2 of sludge higher than radome fairing lower openings and sedimentation basin bottom surface Distance h1 so that enter sludge blanket after wastewater influent, double action caught by the filtering of sludge blanket and net, improves sludgd deposition Rate, water outlet band mud rate is reduced, reduces the use of coagulant, reduces cost.
