Description of drawings
Fig. 1 is the longitdinal cross-section diagram of the second pond of the utility model.
Fig. 2 is the vertical view of the second pond of the utility model.
The specific embodiment:
The preferred implementation of the utility model is described below in conjunction with accompanying drawing.
Fig. 1 is the longitdinal cross-section diagram of the second pond of the utility model, and Fig. 2 is the vertical view of the second pond of the utility model.
Referring to Fig. 1 and Fig. 2, comprise pond 1, effluent trough 2 and mud scum baffle plate 5 according to the second pond of the utility model embodiment.
Effluent trough 2 by the sidewall in pond 1, from the pond the extend internally base of equal length and form clear water output 4 and effluent trough 2 fluid communication of 1 sidewall from the cylindric overflow plate that the inward flange on base extends upward equal altitudes.Shown in the arrow among Fig. 13, clear water is crossed the top edge of cylindric overflow plate, gets into effluent trough 2, and goes out 4 through clear water and be discharged to 1 outside, pond.
Mud scum baffle plate 5 comprises cylindrical section that is positioned at effluent trough 2 inboards and the up-small and down-big round platform section that is connected the cylindrical section lower end; Wherein, The top edge of cylindrical section is higher than the overflow plate height of effluent trough 2, and the distance between the sidewall in the lower limb of round platform section and pond 1 is 3 to 8 centimetres.
Because the top edge of cylindrical section is higher than the overflow plate height of effluent trough 2, so the floating thing on the water surface in the zone that cylindrical section limits is blocked by mud scum baffle plate 5, the top edge that can not cross cylindrical section flows near the effluent trough 2, has therefore guaranteed effluent characteristics.
Because the distance between the sidewall in the lower limb of round platform section and pond 1 is 3 to 8 centimetres; When so any possible floating thing from the bottom, pond floats; To be directed on the water surface that cylindrical section limits by the round platform section, and be unlikely to float near the effluent trough 2 on 3 to 8 centimetres of gaps between the sidewall in lower limb and pond 1 through the round platform section.This is because mostly the supernatant in the sewage is the thin slice bulk, and wherein comprises a large amount of bubbles, in water, is rendered as floating state, and its minimum dimension is generally all greater than 8 centimetres.When the distance between the sidewall in the lower limb of round platform section and pond 1 during less than 3 centimetres; When passing through sewage import 7 to pond 1 water filling; The water flow velocity that gap between the sidewall in the lower limb of round platform section and pond 1 is passed through is very fast; The dirt that size is less is brought near the effluent trough 2 easily, influences effluent characteristics easily.More preferably 5 to 6 centimetres of distances between the sidewall in the lower limb of round platform section and pond 1.Shown in the arrow among Fig. 16, the floating thing of come-up tilts to move up along the inwall of the round platform section of mud scum baffle plate 5, finally gets into the water surface of the cylindrical section localized area of mud scum baffle plate 5.
In an embodiment of the utility model, sewage import 7 is connected with Aerobic Pond through pipeline, and sewage import 7 is guided to the position of underwater apart from 800 to 1000 millimeters of the waters surface through pipeline.Because the position of sewage import 7 between at the bottom of the water surface and the pond so be unlikely to the floating thing and the mud at the bottom of the pond of the water surface are produced too much influence through the sewage in the sewage import 7 entering ponds 1, helps the sedimentation effect in pond.
In an embodiment of the utility model; Second pond also comprises through striking off the mud scraper plate 13 of pond 1 bottom mud and the sludge pump (not shown) that is connected through pipeline 12 with 1 bottom, pond around 1 center, pond rotation, and sludge pump is discharged mud when striking off the mud of 1 bottom, pond at mud scraper plate 13.
In the embodiment of the utility model; Second pond also comprises from the upwardly extending bearing of sewage import 7 14, the mud scraper arm 8 that is arranged on the rotary power system 15 on the bearing and driven by rotary power system 15; Mud scraper arm 8 from the pond 1 central horizontal leading thread to the edge that extends to pond 1; And support by the roller bearing on 1 edge, pond 16, thereby when it rotates around 1 center, pond, strike off the lip-deep dirt of sewage in the pond.
In an embodiment of the utility model; Mud scraper arm 8 is provided with from mud scraper arm 8 to the froth paddle that extends below 9 near the inboard position of the cylindrical section top edge of mud scum baffle plate 5; And second pond comprises the foam whereabouts mouth 10 that exceeds the sewage surface on a position corresponding to froth paddle 9 on the radial dimension, its underpart is guided 1 outside, pond into through foam efferent duct 11.
In an embodiment of the utility model, mud scraper plate 13 flexibly connects through flexible connecting member and the mud scraper arm 8 such as steel wire rope.
In an embodiment of the utility model; Mud scraper arm 8 also from the pond 1 center flatly radially extend certain length going up in the opposite direction; And mud scraper plate 13 is that 13, two the mud scraper plates 13 of two mud scraper plates about pond 1 center symmetric arrangement flexibly connect through flexible connecting member and mud scraper arm 8.
The second pond of the utility model is through being designed to mud scum baffle plate 5 to comprise cylindrical section that is positioned at effluent trough 2 inboards and the up-small and down-big round platform section that is connected the cylindrical section lower end; Wherein, The top edge of cylindrical section is higher than the overflow plate height of effluent trough 2; And the distance between the sidewall in the lower limb of round platform section and pond 1 is 3 to 8 centimetres; Can when mud scraper plate 13 is scraped mud, avoid mud scum to be accompanied by bubble and get into effluent trough 2, but be limited to the regional interior of mud scum baffle plate 5 qualifications and further processing of quilt, so improve the effluent characteristics of second pond.
Those skilled in the art should be understood that, according to design demand and other factors, can carry out various modifications, combination, part combination and replacement.Such modification, combination, part combine and replacement falls within the scope of accompanying claims or its equivalent.
