Description
Technical field
The present invention relates to water-treatment technology field, especially relate to the treatment facility of waste water or sewage, specifically a kind of rectangular sedimentation tank of processing heavy metal wastewater thereby.
Background technology
Heavy metal wastewater thereby refers to the waste water that contains heavy metal of discharging in the industrial processes such as mining and metallurgy, machine-building, chemical industry, electronics, instrument.Heavy metal (as containing cadmium, nickel, mercury, zinc etc.) waste water is the most serious to an environmental pollution and the mankind endangered one of maximum industrial wastewater, and its water quality and quantity is relevant with production technology.Heavy metal in the waste water is that various common methods can not be decomposed destruction, and can only shift their location and change their physics and chemistry form.For example, after chemical precipitation was processed, the heavy metal in the waste water was transformed into insoluble chemical compound and precipitates from the ionic condition of dissolving, transfers in the mud from water.Existing sedimentation basin is generally the slope fluidal texture, and its sedimentation effect is bad, and the precipitation material also easily is flushed away, and in use often can and situation not up to standard occur service time in later stage owing to artificial installation factor, and processing cost is high.
Summary of the invention
The objective of the invention is the defective for prior art, provide a kind of simple in structure, cleaning is convenient and effective rectangular sedimentation tank.
The objective of the invention is to solve by the following technical programs:
A kind of rectangular sedimentation tank, comprise the pond body, be respectively equipped with water inlet and delivery port on the two ends sidewall of pond body, the inside of pond body is divided into the cloth pool, settling zone and advection district, wherein the water distribution district be positioned at water inlet at one end the pond body and separate mutually by the settling zone of next door and its downside and the advection district of its side, the bottom in cloth pool is provided with the limbers that is connected with the settling zone of its downside, cloth pool and settling zone are positioned at the homonymy in advection district, the bottom in described advection district is horizontal plane, the bottom of settling zone is provided with the sludge-tank on plane of living in, bottom, downward protrusion advection district, and the sidewall of described sludge-tank is provided with mudhole.
The vertical section of described sludge-tank is right-angled trapezium.
The hypotenuse of described sludge-tank and the angle between the vertical curve are 50 °-60 °.
Described mudhole is positioned on the sidewall at right-angle side place of sludge-tank.
Described mudhole is positioned at the downside of water inlet.
The ratio of the width of described cloth pool and settling zone is 1:1.5-3.
Described water inlet is positioned on the pond body sidewall at place, cloth pool.
The upside in described advection district is provided with overflow area, is provided with the overflow launder that is connected with delivery port in the overflow area.
The present invention has the following advantages compared to existing technology:
Rectangular sedimentation tank of the present invention has been avoided the troublesome operation of inclined tube filler, have simple in structure, cleaning is convenient and effective characteristics.
Size between overall structure of the present invention and each subregion can greatly reduce occupation of land space and equipment cost according to the design for the treatment of capacity and processing speed, and suitable all kinds of blowdown enterprise uses.

Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-pond body; 2-water inlet; 3-delivery port; 4-cloth pool; 5-settling zone; 6-advection district; 7-next door; 8-limbers; 9-sludge-tank; 10-mudhole; 11-overflow area; 12-overflow launder.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of rectangular sedimentation tank, comprise pond body 1, be respectively equipped with the water inlet 2 of introducing sewage and the delivery port 3 that flows out supernatant on the two ends sidewall of pond body 1.The inside of pond body 1 is divided into cloth pool 4, settling zone 5 and advection district 6, wherein cloth pool 4 and settling zone 5 are positioned at the homonymy in advection district 6, cloth pool 4 be positioned at 2 of water inlets at one end pond body 1 and water inlet 2 be positioned at 4 places, cloth pool pond body 1 sidewall on, also separate mutually by next door 7 and the settling zone 5 of its downside and the advection district 6 of its side in cloth pool 4, the bottom in cloth pool 4 is provided with the limbers 8 that is connected with the settling zone 5 of its downside, in order to obtain better sedimentation effect, the ratio of the width of cloth pool 4 and settling zone 5 is 1:1.5-3, so that the sewage that falls under gravity into settling zone 5 by limbers 8 is better precipitated; 5 bottom also is provided with the downward sludge-tank 9 that the bottom is the plane of living in, 6 bottoms, advection district of horizontal plane that protrudes in the settling zone, the vertical section of this sludge-tank 9 is right-angled trapezium, angle between its hypotenuse and the vertical curve is 50 °-60 °, also be provided with mudhole 10 on the sidewall at the right-angle side place of sludge-tank 9, mudhole 10 and water inlet 2 are positioned on the same sidewall of pond body 1 and are positioned at the downside of water inlet 2.In order to obtain preferably supernatant of water quality, the upside in advection district 6 is provided with overflow area 11 in addition, is provided with the overflow launder 12 that is connected with delivery port 3 in the overflow area 11.
The present invention in use, heavy metal wastewater thereby flows into cloth pool 4 from water inlet 2, in cloth pool 4, be added with incessantly coagulant and flocculation aid, the heavy metal wastewater thereby that is added with coagulant and flocculation aid falls in the settling zone 5 by limbers 8 under action of gravitation, in the decline process, precipitation in the waste water constantly falls in the sludge-tank 9 and by mudhole 10 and discharges, current then constantly circulate between settling zone 5 and advection district 6, water in the advection district 6 is from top to bottom then by clear extremely turbid, turbid liquid constantly is circulated to settling zone 5 interior precipitations, the supernatant then crest of weir of the overflow launder 12 in the overflow area 11 is spilled over to delivery port 3, enters next step treatment process.
The technology that the present invention does not relate to all can be realized by prior art.
