Abstract
A water-saving settling pond consists of a two-layer horizontal flow settling section placed at the front and a tilted plate settling section placed at the back and communicating with the two-layer settling section, wherein the two-layer horizontal flow settling section consists of an upper layer of settling section and a lower layer of settling section, and each layer of settling section is internally provided with a reciprocating mud scraper; the upper layer of settling section and the lower layer of settling section run in parallel, the joint of the tail end of the upper layer of horizontal flow settling section and the lower layer of settling section are provided with holes, and the tail end of the upper layer of horizontal flow settling section is provided with a sump tank; the tilted plate settling section consists of a plurality of tilted plate cases, and a plurality of perforated sump tanks are adopted at the water outlet. The water-saving settling pond has the greatest advantages of being capable of improving the whole solid content of discharged mud water of the settling pond and reducing the quantity of discharged mud water without affecting the effluent quality.
Description
Technical field:
The utility model belongs to a kind of water treatment facilities, particularly a kind of water-saving sedimentation basin.
Background technology:
China's urbanization is in Rapid development stage, and urban water conservation is solving China's water scarcity, ensures that the urban water supply secure context has very outstanding status.The water saving of urban water supply factory is the requisite important step of urban water conservation.The minimizing of water-supply plant spoil disposal water is one of major measure of water-supply plant water saving, and China's great majority are that the urban water supply factory spoil disposal water at water source occupies 5%～8% of the water yield with the surface water, have very big water saving potential.It is reported that China waterworks is in service in the water treatment of routine, sedimentation basin or depositing reservoir spoil disposal water account for 2%～5% of water-supply plant aquifer yield, and filter back washing waste water accounts for 3%～6% of total aquifer yield.How much being closely related of the spoil disposal water yield with precipitation, spoil disposal etc., precipitation, spoil disposal key technology that research is suitable, develop water-saving sedimentation basin and spoil disposal machinery, improve the whole solid content of sludge from sedimentation tank water, to reduce the spoil disposal water yield and reduce the water-supply plant self water consumption, improve China's waterworks water saving and have active operation significance comprehensively.Existing horizontal sedimentation tank, combined type sedimentation basin floor space is big, deposition efficiency is low, a little less than the anti impulsion load, and the whole solid content of sludge from sedimentation tank water is low, spoil disposal water yield height.
Summary of the invention:
The purpose of this utility model is to provide a kind of water-saving sedimentation basin, it not only have occupation of land less, advantage such as deposition efficiency height, anti impulsion load be strong, also crucially be that it can improve the whole solid content of sludge from sedimentation tank water, reduce the spoil disposal water yield, can economize on water.
As above design, the technical solution of the utility model is: a kind of water-saving sedimentation basin, comprise the pond body, it is characterized in that: by placing anterior double-deck advection sedimentation section and the sloping plate deposition section that places the rear portion and communicate to form with the two-story sedimentation section; Double-deck advection sedimentation section is made up of upper and lower layer precipitating phase, and reciprocating type mud scraper is installed in every layer of precipitating phase; Upper and lower layer precipitating phase is parallel running, the terminal and lower sediment section junction perforate of upper strata advection sedimentation section, and upper strata advection sedimentation section end is provided with water leg; The sloping plate deposition section is made up of several tilting box, and its delivery port adopts many perforation water legs.
The upper and lower rate ratio of opening of the water inlet water distribution tracery wall of above-mentioned upper and lower layer precipitating phase is 1: 3～3: 3.
The advection sedimentation section terminal long ratio of length and the total pond of sedimentation basin with the perforate of lower sediment section junction in above-mentioned upper strata is 1: 50～1: 10.
Above-mentioned upper strata advection sedimentation section end is provided with 1～5 road water leg.
The utlity model has following advantage and good effect:
1, under the situation that does not influence effluent quality, can improve the whole solid content of sludge from sedimentation tank water, reduce the spoil disposal water yield, save the self water consumption of waterworks.
2, take up an area of less, deposition efficiency height, anti impulsion load be strong.
Description of drawings:
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment:
A kind of water-saving sedimentation basin is by placing anterior double-deck advection sedimentation section 1 and the sloping plate deposition section 2 that places the rear portion and communicate with the two-story sedimentation section to form.Double-deck advection sedimentation section is made up of upper and lower layer precipitating phase, and reciprocating type mud scraper is installed in every layer of precipitating phase; Upper and lower layer precipitating phase is parallel running, and the rate of opening the up and down ratio of upper and lower layer precipitating phase water inlet water distribution tracery wall 3 is 1: 3～3: 3, and the spoil disposal of upper and lower layer can independently be discharged also and can be merged discharge; Terminal and the lower sediment section junction perforate 4 of upper strata advection sedimentation section, the long ratio in the total pond of perforate length and sedimentation basin is 1: 50～1: 10; Upper strata advection sedimentation section end is provided with 5 water outlets of twice water leg.
The sloping plate deposition section is arranged on the back of two-story sedimentation section, and its effect is to hold back the tiny flco that advection Duan Wei precipitates, and further reduces delivery turbidity, the reinforced deposition effect.The sloping plate deposition section is made up of several tilting box 6, and its delivery port adopts many perforation water legs 7.
