Embodiment 1

[0027] The sewage in a river in Zhejiang belongs to black and odorous water body, the water body is black and gray with a pungent odor, and the area of ​​the river to be treated is 14,000m2 2 , the water volume is 30000m 3 , dissolved oxygen is 0 ~ 0.3mg / L, COD is 64mg / L, ammonia nitrogen is 18mg / L, along the center of the river, evenly place 5 new river water purification devices, each device is two meters in diameter, immobilized bacteria The total amount of agent filling is 200kg, of which the immobilized catalyst for removing organic matter accounts for 40%, and the immobilized catalyst for removing ammonia nitrogen accounts for 60%. After 5-7 days of treatment, the black odor and peculiar smell of the water body are eliminated, and the COD of the water body is below 40mg / L , ammonia nitrogen is below 2mg / L, dissolved oxygen is above 2mg / L, and water clarity is above 0.5m.

Embodiment 2

[0029] Due to long-term domestic sewage discharge, a pit in Hebei has become a black and odorous water body. After plugging the pollution source and dredging the bottom of the pit and pond, the water quality of the pit and pond will be treated. The shape of the pond is about a rectangle, with a length of about 50m and a width of about 20m. The average water depth is 3m and the water volume is about 3000m. 3 , the water COD is 120mg / L, and the ammonia nitrogen is 25mg / L. A new type of river water purification device with a diameter of 2m is placed at each end of the pit and pond, and is treated together with two push-flow devices. The total filling amount of the immobilized bacterial agent is 200kg, of which the immobilized catalyst for removing organic matter accounts for 70%, and the immobilized catalyst for removing ammonia nitrogen accounts for 30%. .

Embodiment 3

[0031] The river water of a river in Nantong, Jiangsu belongs to the inferior five water bodies. Due to the imperfect laying of the sewage pipe network on both sides of the river, the washing wastewater and kitchen sewage of the surrounding residents will be discharged into the river at any time. The river is mainly ammonia nitrogen and total phosphorus exceeding the standard. ~ 8mg / L. In this case, the present invention is used to treat the ammonia nitrogen in the river. A new type of river water purification device with a diameter of 1.5m is arranged every 50m, and 100kg of immobilized biocatalysts for degrading ammonia nitrogen are filled. After 20 days of operation, the ammonia nitrogen in the water body of the whole treated river was basically maintained at about 1.5mg / L, and the operation was stable.

Abstract

The invention discloses a novel riverway water purification device which is characterized in that the device mainly comprises a lotus base body, a floating body and a submersible pump, the floating body is arranged at the bottom of the lotus base body, the lotus base body is of a concave structure, at least two concentric circle partition plates are arranged on the upper end face of the lotus base body, an immobilized biocatalyst is arranged between partition plates on the upper end face of the lotus base body, a fountain spray head is arranged in the center of the upper end face of the lotus base body and communicated with a submersible pump through a water feeding pipeline, the gravity center of the submersible pump and the gravity center of the whole equipment are located on the same vertical line, lotus leaves are arranged on the side face of the lotus base body, and the lotus leaves are distributed in a crossed and multi-layer mode. The device has the advantages that the dissolved oxygen concentration of river water is increased by means of the fountain, waterfall and the like, the degradation rate of pollutants is high, the fountain and the lotus shape are organically combined, and multiple functions of landscaping, aeration, pollutant degradation and the like are integrated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a new type of river water purification device. Background technique [0002] Urban black and odorous water not only brings a very poor sensory experience to the masses, but is also a prominent water environment problem that directly affects the production and life of the masses. Due to the complex causes and many influencing factors of urban water, the task of remediation is very arduous. [0003] When the water body suffers from serious organic pollution, the aerobic decomposition of organic matter makes the oxygen consumption rate in the water body greater than the reoxygenation rate, resulting in anoxic water body, resulting in incomplete degradation of organic matter and slowing down. , mercaptan and other odorous substances, and at the same time form black substances such as FeS and MnS, which make the water body black and odorous. Therefore, restoring dissolved ox...
