Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] Such as figure 1 with figure 2 As shown, the front view and figure view of the self-circulating self-stirring depth denitrification clean water tank of the present invention are provided, and the shown clean water tank is composed of a housing 1, a first dividing plate 5, a second dividing plate 10, a third dividing plate Plate 7, fourth partition 2, one-way valve 16, U-shaped pipe 4, return pipe 3, aeration pipe 11, and gas collection port 6. The housing 1 shown is in the shape of a cuboid, which can be 50-80cm Cube, the interior of the housing 1 is a cavity, and the first partition 5, the second partition 10, the third partition 7 and the fourth partition 2 sequentially separate the internal cavity of the casing 1 into a grid-shaped distribution. The first grid groove 16, the second grid groove 17, the third grid groove 18 and the fourth gri...

The invention provides a self-circulating and self-stirring deep denitrification water purifying tank. The self-circulating and self-stirring deep denitrification water purifying tank comprises a shell and four partition boards arranged in the shell, wherein an inner cavity of the shell is sequentially divided into four cells which are distributed in a matts form by the four partition boards, a return pipe is arranged in the shell, an inlet of the return pipe is located in the third cell and communicates with a gas collecting opening, an aeration pipe penetrates through the gas collecting opening and extends into the return pipe, and small holes are uniformly formed in the aeration pipe; and the lower part of the first partition board is provided with a U-shaped pipe with two upward openings, and the two openings of the U-shaped pipe are separately located in the first cell and the second cell. The water purifying tank has the advantages that 1, by adopting a square reactor, small land is occupied, a base plate is firm, operation is safe and convenient, and processing is simple and feasible; 2, the device belongs to the self-circulating type water purifying tank, self-circulation can be realized through low energy consumption, the value of dissolved oxygen at an anaerobic reaction part is reduced, and the treatment efficiency reaches the maximum value; and 3, the device also belongs to the self-stirring type water purifying tank, stirring can be finished without mechanical assistance, energy consumption is reduced, and cost is saved.
Description
technical field [0001] The invention relates to a water purification tank, more specifically, to a self-circulating self-stirring deep denitrification water purification tank. Background technique [0002] Domestic sewage in most rural areas of our country is discharged without any treatment, causing the overall water quality of rivers in rural areas to deteriorate. Nutrients mainly nitrogen and phosphorus exceed the standard seriously, and some rivers and lakes have shown severe eutrophication. [0003] The low removal rate of the water purification tank technology that has been developed has become a problem encountered by most of the water purification tanks, and the feasibility of the water purification tank has not been considered in consideration of the actual living standards and lifestyles in rural areas. For this reason, a self-circulating self-stirring purification tank has been specially developed, and a technology for self-circulating self-stirring purification t...
