Description
Technical field
The present invention relates to sewage treatment field, more particularly to a kind of municipal sewage system.
Background technology
Sanitary sewage, industrial wastewater and runoff sewage in the range of urban area are the three categories type of municipal wastewater, generally
Collected by city pipe duct and water body should be discharged into after municipal sewage plant is handled, removed in municipal sewage containing a large amount of organic
Object and germ, virus, the processing of municipal sewage are related to many aspects, it is necessary to sewer system, the position of sewage treatment plant and
Treatment process, after processing sewage using and emission request etc. carry out unified plan.
In the prior art, the Authorization Notice No. that can refer to is the Chinese patent of CN204588727U, and it discloses the present invention
It is related to efficient screen drum grid sewage-removing machine.Including screen drum grid, the screen drum grid is mounted on by a live spindle in babinet,
Driving device, which is equipped with, on the right side of babinet live spindle to be driven to rotate, and the screen drum grid gap is 0.5mm ~ 3mm, screen drum grid

Clean brush is rack-mount by a shaft, and box back is equipped with water inlet, and lower end is equipped with discharge outlet, babinet four in the middle part of babinet
Angle is respectively equipped with installation foot, is connect in babinet equipped with overflow ducts with discharge outlet.The configuration of the present invention is simple, it is outside by using diameter
Narrow interior broad gap is the screen drum grid of 0.5mm ~ 3mm, it is impossible to detach the fine impurities of below 3mm, and water amount is big, screen drum
Grid outer surface sundries is convenient to clean, and is not easy to plug, and filter efficiency is high, gives up more suitable for industries such as textile printing and dyeing, chemical industry, papermaking
The fiber-likes impurity such as water pretreatment is thin, short, broken separation.
Current grid sewage-removing machine by many a grid teeth on screen drum grid by sewage suspended solid pollutant, have
Some things such as machine pollutant and noxious material are pulled out, then handle the thing pulled out, but due to two neighboring grid
Tooth has no small gap, and grid tooth is when dragging for slag, it is difficult to pull the smaller dirt in sewage out, the dirt in such sewage is pulled out
It is unclean, if these dirts are discharged, will rivers and lakes be caused with very serious pollution.
Invention content
The object of the present invention is to provide a kind of municipal sewage systems, have the size dirt in sewage is more abundant
The purpose pulled out.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of municipal sewage system, its key points of the technical solution are that transmission device including frame body, in frame body and being located at
Waste-removing device is removed at transmission device rear, and the transmission device includes carrying out the connecting rod of shuttling movement, the outside of the connecting rod
Multiple fishing slag plates are installed with, multiple filter openings being uniformly arranged are offered on the fishing slag plate, the fishing slag plate is located at the outer of frame body
Portion, the outer end of the fishing slag plate turn down to form hook.
By using said program, the reciprocating motion of multiple connecting rods progress back and forth, Jin Erlian are driven by transmission device
Extension bar drive fishing slag plate slowly moved on frame body, when drag for slag plate run to the bottom of frame body when hook by sewage dirt drag for
Go out, filter opening can filter out sewage, and since filter opening is smaller, dirt can not be flowed out from filter opening, and such sewage is walked through dragging for slag plate fishing
Dirt residual is less afterwards.
