Abstract
The utility model relates to a falling water aeration and filtering tank for iron elimination and manganese elimination of underground water. The utility model is characterized in that the lower part of a gravity type filtering tank is orderly provided with falling water grooves with a sloping lower bottom, a material filtering device, and a water discharging device; both sides of the upper part of a water inlet channel is provided with the falling water grooves; one side of the upper part of each falling water groove is provided with falling water weir; the pipe line of the water discharging device is connected with a filtered pipe, a back flushing pipe, and an evacuating pipe; the lower bottom of the water inlet channel is provided with a waste water pipe which is communicated with the water discharging device. The utility model has the advantages of simple structure, small ground occupation, convenient maintenance, and less investment.
Description
The utility model relates to a kind of filter tank, particularly relates to a kind of underground water deferrization and demanganization drop water aeration and filtering integral filter tank.
At present, the following water deferrization and demanganization filter tank of employing is to connect gravity one by the drop water aeration pond by the aeration tank rising pipe, and the gravity aeration tank divides into the installation water injection pipe, and this plant area area is big, and investment is big, the cost height.
It is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, and floor space is little, the underground water deferrization and demanganization drop water aeration of less investment and filtering integral filter tank.
In order to achieve the above object, the technical solution adopted in the utility model is: the gravity one bottom is provided with drop chute, filtrate and the water-freeing arrangement that band tilts to go to the bottom successively, both sides are provided with drop chute above inlet channel, drop chute top one side is provided with the drop weir, join with filtration pipe, backwash tube, blow-down pipe respectively on the pipeline of water-freeing arrangement, inlet channel is gone to the bottom and is provided with the waste pipe that is connected with water-freeing arrangement.
The utility model has the advantages that:
1, reduces floor space 20-30% between water purification car;
2, adopt integrated inlet channel drop water aeration filter tank, can save water treatment workshop capital construction investment 10-20%;
3, drop water aeration and filtering integral filter tank are applicable to the new water factory of design and construction, are applicable to that also old water factory transforms;
4, management, easy to maintenance;
5, hydraulic condition is good, and the aeration effect is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is to be provided with drop chute 6, filtrate 7 and the water-freeing arrangement 8 that band tilts to go to the bottom successively in gravity one 5 bottoms, both sides are provided with drop chute 1 above inlet channel 4, drop chute 1 top one side is provided with drop weir 9, join with filtration pipe 11, backwash tube 10, blow-down pipe 3 respectively on the pipeline of water-freeing arrangement 8, inlet channel 4 is gone to the bottom and is provided with the waste pipe 2 that is connected with water-freeing arrangement 8.
The utility model calculates that according to the planar dimension and the filtering velocity in current deferrization and demanganization filter tank the inlet channel drop water aeration is loaded at 20-120m
3In/mh the scope, can guarantee the requirement of drop water aeration dissolved oxygen fully.
Top water-level above protection to the edge, pond in filter tank highly is 0.3m; gravity type boat davit deironing filter tank is for becoming filtering velocity work; treat in the filter tank that drainage liquid level absolute altitude changes; basically be to push up following 0.3m to the pond from wash water groove upper edge; variation range is generally about 1.5m; drop chute weir crest height can be designed to 1m; so total drop highly changes; it is above-mentioned three's sum; drop highly is 2.8m when starting working behind filter back washing, and along with the prolongation of filter tank working hour, liquid level constantly rises in the filter tank; drop highly constantly reduces, and drop highly is 1.3m before filter back washing.
After water aeration fell into the filter tank inlet channel, liquid level produced fluctuation in the canal, enter the filter tank by the wash water groove after the water surface very steady, can not influence filter tank work.
Oxygen in water content behind the aeration, relevant with aeration load, drop height, aeration place airiness situation with water temp, inlet channel drop water aeration effect and special-purpose aeration tank aeration effect basically identical, the oxygen in water saturation ratio can reach about 50-80% behind the aeration.
