Abstract
The invention belongs to the technical field of water treatment, and particularly relates to a rain and sewage flow diversion system for a steel-making plant. The rain and sewage flow diversion system for the steel-making plant comprises a rainwater collecting system and a sewage collecting system. The sewage collecting system is sequentially provided with a sewage collecting canal I, a sewage collecting canal II and a lift pump in the sewage flow direction. The sewage collecting canal I is connected with the sewage collecting canal II through a collecting pipe and a valve. A water outlet of the sewage collecting canal II is connected with an inlet of the lift pump through a collecting pipe and a valve. A water supply pipeline is arranged on an outlet of the lift pump and connected to a sewage treatment plant. The flow diversion system is reasonable and practical in design, rainwater and sewage can be separately and independently treated, especially during the rainy season, the phenomenon of sewage treatment overload is avoided, and the problem that the sewage is drained along with the rainwater is solved.
Description
Technical field
The invention belongs to the technical field of water treatment, be specifically related to the dirty separate system of a kind of rain for steel mill.
Background technology
The existing water treatment system of current steel mill adopts drainage pattern sanitary sewage, rainwater and production waste drainage being carried out combined system, and as the final Rendezvous Point of all sewage draining exits, under normal production status, the rear reuse of composite wastewater treatment plant process is delivered to, fraction sewage standard discharge after most of sewage pressurization after collecting.But in rainy season, because the total Water being pooled to final Rendezvous Point exceedes composite wastewater treatment plant disposal ability, part producing waste water and rainwater overflow together, cause environmental protection to exceed standard.
Summary of the invention
The object of the invention is to occur because of sewage treatment capacity overburden in rainy season for current steel mill, the phenomenon causing sewage to be arranged with rainwater outward and provide a kind of rain for steel mill dirty separate system, the practicality reasonable in design of this separate system, what achieve rainwater and sewage separates independent process, especially in rainy season, avoid the phenomenon of sewerage treatment overburden, thus solve the problem that sewage arranges with rainwater outward.
Technical scheme of the present invention is: the dirty separate system of a kind of rain for steel mill, comprises rain water collecting system and sewage
Gathering system, wherein sewage collection system includes sewage collecting water channel I, sewage collecting water channel II and lift pump along effluent stream to setting gradually; Sewage collecting water channel I is connected with sewage collecting water channel II with valve by collecting pipe, and the delivery port of sewage collecting water channel II is connected with the import of lift pump with valve by collecting pipe; The exit of lift pump is provided with water supply line, and this water supply line is connected to Wastewater Treatment Plant.
Described sewage collecting water channel I and sewage collecting water channel II are equipped with manhole.
Headstock gear is provided with between described rain water collecting system and the import of lift pump.
The diameter of described collecting pipe is 1.2m.
The length of described sewage collecting water channel I and sewage collecting water channel II is 2m, is widely 2m.
The length of described headstock gear is 2m, and wide is 2m.
The diameter of described water supply line is 0.8m.
The storm sewer that diameter is 0.5m is arranged with in described rain water collecting system.
Described storm sewer is in parallel with water supply line to distribute.
Beneficial effect of the present invention is: the dirty separate system of the rain for steel mill of the present invention, rainwater and the process of sewage is thoroughly separated independent operating, improves region closed cycle level, region improvement up to standard and blowdown decrement.First be collect the sewage that exceeds standard, closed conveying directly enters composite wastewater treatment plant, stops to enter river course.By the dirty separate system of described rain, the equal qualified discharge of waste water of all directly outer rows, in non-rainy season, rain water collecting system can be used as the breach of comprehensive dirty disposal ability deficiency; In rainy season, all rainwater collected are not collected, and the sewage of centralized collection still discharges for collaborating rainy season.
Wherein adopting sewage collecting water channel I and sewage collecting water channel II two collection water channels to the design of sewage collection system, greatly reducing the impact load of sewage to system like this, greatly extending the application life of system and enhancing the disposal ability of system.Described valve switch all realizes gravity flow according to the change of respective row water pressure, and lift pump achieves automatic control.
In sum, the dirty separate system of this rain solves rainwater and production waste dual disposal and the problem of environmental pollution that causes.System is rationally simple, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation for the dirty separate system of the rain of steel mill in the specific embodiment of the invention.
Wherein, 1 is rain water collecting system, and 2 be sewage collecting water channel I, 3 be sewage collecting water channel II, 4 is lift pump, and 5 is collecting pipe, and 6 is valve, and 7 is water supply line.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
As can be seen from Figure 1, the dirty separate system of rain for steel mill of the present invention, comprise rain water collecting system 1 and sewage collection system, wherein sewage collection system includes sewage collecting water channel I 2, sewage collecting water channel II 3 and lift pump 4 along effluent stream to setting gradually; Sewage collecting water channel I 2 is connected with sewage collecting water channel II 3 with valve 6 by collecting pipe 5, and the delivery port of sewage collecting water channel II 3 is connected with the import of valve 6 with lift pump 4 by collecting pipe 5; The exit of lift pump 4 is provided with water supply line 7, and this water supply line 7 is connected to Wastewater Treatment Plant.
Described sewage collecting water channel I 2 and sewage collecting water channel II 3 are equipped with manhole.
Headstock gear is provided with between described rain water collecting system 1 and the import of lift pump 4.
The diameter of described collecting pipe 5 is 1.2m.
The length of described sewage collecting water channel I 2 and sewage collecting water channel II 3 is 2m, is widely 2m.
The length of described headstock gear is 2m, and wide is 2m.
The diameter of described water supply line 7 is 0.8m.
The storm sewer that diameter is 0.5m is arranged with in described rain water collecting system 1.
Described storm sewer is in parallel with water supply line 7 to distribute.
In non-rainy season: after all production wastes are collected by sewage collecting water channel I 2 and sewage collecting water channel II 3, sewage is delivered to Wastewater Treatment Plant by lift pump 4; And the rainwater collected by rain water collecting system can enter Wastewater Treatment Plant by headstock gear and lift pump, as the breach of comprehensive dirty disposal ability deficiency.
In rainy season: after all production wastes are collected by sewage collecting water channel I 2 and sewage collecting water channel II 3, sewage is delivered to Wastewater Treatment Plant by lift pump 4; And the rainwater that rain water collecting system is collected directly is disposed to river course, Wastewater Treatment Plant can not be affected.
