Problems solved by technology

However, since the inner and outer pipes are connected to each other and are subject to the same lifting force of the impeller, and the inner pipe is filled with filter fillers, the sewage can easily pass through the outer pipe with less resistance, forming a short flow, that is, the sewage does not fully enter into the filter filled with biological fillers. The inner tube carries out biochemical reactions
[0006] Moreover, there are common problems in the research of biological fillers filled in existing water purification equipment: first, the fillers of the facilities have low removal efficiency for COD, BOD and other pollutants in the water body, the purification effect is unstable, and the service life is short
Second, in the water body with low pollution concentration range, due to the lack of carbon source, the removal rate of total nitrogen is very low

Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, it is a submersible landscape water purification device with denitrification function provided in Embodiment 1 of the present invention, which includes a gas buoy and a purification packing tank.

[0032] The purification stuffing tank includes a tank body, which is respectively provided with a denitrification packing layer 8, an aeration device 7 and a biological enzyme charcoal packing layer 5 from bottom to top. In this embodiment, water-permeable screens 6 are provided above and below the denitrification packing layer 8 and above and below the bio-enzyme charcoal packing layer 5 .

[0033]The gas buoy includes a gas buoyancy ring 1, a gas buoyancy ring cover 2 arranged above the gas buoyancy ring 1, a gas control valve 3 and a level control device. The gas control valve 3 is used to regulate the amount of air entering the gas floating ring 1 . The level control device is used to maintain the balance of the water purification...

Embodiment 2

[0045] This embodiment is roughly the same as Example 1, except that the biological enzyme charcoal filler in the biological enzyme charcoal filler layer 5 is prepared by the following method:

[0046] Add 30% modifier of the weight of the charcoal to the charcoal with a particle diameter of 6-20mm that has been vibrating, sieved and rounded, and add 30% of the weight of the charcoal as a modifier, wherein in the modifier's A liquid, 1% of amino grape pond, 2.5% of glucosamine hydrochloride %, the balance is water. The function of liquid A is to modify the surface of charcoal, use the amino group of glucosamine and glucosamine hydrochloride to neutralize the charge on the surface of charcoal, and provide a biological carrier for immobilizing microorganisms and biological enzymes. The B liquid of the modifier contains 10% corn steep liquor , peptone 5%, iron sulfate 0.1%, potassium dihydrogen phosphate 0.2%, yeast 1%, and the balance is water. The role of liquid B is mainly to...

Embodiment 3

[0053] This embodiment is roughly the same as Example 1, except that the biological enzyme charcoal filler in the biological enzyme charcoal filler layer 5 is prepared by the following method:

[0054] Add 30% modifier of the weight of the charcoal to the charcoal that has been vibrating, sieved and rounded with a particle diameter of 6-20 mm, in which 1.5% of grape amino hydrochloride and glucosamine sulfate are added in liquid A of the modifier. 1.2%, the balance is water. The function of liquid A is to modify the surface of charcoal, neutralize the charge on the surface of charcoal by using the amino group of glucosamine hydrochloride and glucosamine sulfate, and provide a biological carrier for immobilizing microorganisms and biological enzymes. In liquid B of the modifier, corn steep liquor 5 %, peptone 4%, potassium dihydrogen phosphate 0.2%, magnesium sulfate 0.1%, yeast 1.5%, and the balance is water. The role of liquid B is mainly to provide nutrients and trace elemen...

Abstract

The invention provides a submersible-type device for purifying water quality of a landscape water body and with a denitrification function. The submersible-type device comprises an air float bowl and a purification stuffing tank, wherein the purification stuffing tank comprises a tank body, and a denitrification stuffing layer, an aeration device and a biological enzyme charcoal stuffing layer are arranged in the tank body from bottom to top; the air float bowl comprises an air float ring, an air control valve and a horizontal control device, the tank body of the purification stuffing tank is sleeved with the air float ring, the air control valve is used for regulating the amount of air entering the air float ring, the horizontal control device is used for maintaining the balance of the water quality purification device, and water flows upwards from the bottom of the tank body and flows out of the top of the tank body after interacting with the denitrification stuffing layer and the biological enzyme charcoal stuffing layer. The purification device can efficiently remove BOD (biochemical oxygen demand), COD (chemical oxygen demand) and other pollutants in the water body for a long time and can also remove ammonia nitrogen and total nitrogen of the water body.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a submersible landscape water purification device with denitrification function. Background technique [0002] With the improvement of living standards, people's pursuit of living environment is getting higher and higher, and more and more landscape water bodies have appeared. Most of these landscape water parks and communities are closed water bodies excavated manually. The self-purification ability of the water body is inherently weak. Due to the continuous impact of other natural pollution such as surrounding domestic sewage and rain runoff, the water quality is unstable and serious occurrence of blue-green algae, The water quality is black and smelly, and the breeding of mosquitoes and flies seriously affects the environment of the surrounding area. [0003] At present, there are basically two methods adopted in China. One is the treatment outside the pool, ...
