Problems solved by technology

[0006] When the existing biological synergy technology is applied to domestic or sewage treatment activated sludge process, there is a contradiction between the amount of dissolved oxygen in the aerobic tank and the demand for high-efficiency bacteria. When the high-efficiency bacteria reproduce and transform ammonia nitrogen, High dissolved oxygen is required, but too high dissolved oxygen will affect the sedimentation performance of sludge
There is also an overall increase in dissolved oxygen in the aerobic pool, the utilization rate of oxygen is low, and the cost of sewage treatment will increase
[0007] When the existing bio-enhancement technology is applied to the treatment of surface water bodies, especially river water, there are defects such as large amount of strains used, high cost of use, unstable effect, and easy loss of strains.

Embodiment 1

[0029] Embodiment 1 A biological synergistic device for water treatment, comprising a top feeding pan 1, a middle aeration box 2 and a bottom aeration box 3, the feeding pan 1, the middle aeration box 2 and the bottom aeration box 3 are all It is a net cage structure, and the bottom of the feeding pan 1 is tenoned with the top of the middle oxygenation box 2, the bottom of the middle oxygenation box 2 is tenoned with the top of the bottom oxygenation box 3, and the The middle aeration box 2 is equipped with a first aeration device 21, the bottom aeration box 3 is equipped with a second aeration device 31, the first aeration device 21, the second aeration device The gas device 31 communicates with the aeration pump through the corresponding first air inlet pipe 22 and the second air inlet pipe 32 respectively; the described middle aeration box 2 is filled with organic spherical bacteria cultivation carrier 23; the bottom aeration box 3 It is filled with inorganic mineral compou...

Embodiment 2

[0042] Embodiment 2 aquarium industry

[0043] 5×30×1.5m courtyard pool for breeding ornamental fish, the average water transparency is 10cm, ammonia nitrogen 0.7mg / L, nitrite 0.2mg / L, nitrate 120mg / L (calculated as N), and a microorganism is placed at an interval of about 10 meters There are 2 boosters in total. For the first time, 10g of commercially available Anmi brand nitrifying bacteria freeze-dried powder was added, and an appropriate amount of Weixi brand microbial nutrient was added once a day, and the oxygen content of the water was kept at 5 mg / L by continuous oxygen exposure. The water quality was measured for the first time after 24 hours, ammonia nitrogen 0.2mg / L, nitrite 0.01mg / L, nitrate 50mg / L. After 48 hours, the water quality was measured for the second time, ammonia nitrogen 0.05mg / L, nitrite 0.005mg / L, nitrate 12.5mg / L. After 72 hours, the water quality was measured for the third time. The ammonia nitrogen, nitrite, and nitrate were basically zero, and t...

Embodiment 3

[0044] Embodiment 3, pond culture

[0045] The breeding pond covers an area of ​​about 500 square meters, and the water depth is 1.5-2 meters. An average of 100 square meters is placed with a microbial enhancement device, and a total of 5 are placed. Put 200g of commercially available Anmi brand nitrifying bacteria freeze-dried powder, add an appropriate amount of Weixi brand microbial nutrient once a day, and continue aeration to keep the oxygen content of the water above 5mg / L. After 3-5 days, the water quality will reach the health index. Due to the large water body, the establishment of the microbial purification system will be affected by more factors. By testing the water quality the next day, add an appropriate amount of microbial nutrients.

Abstract

A bioaugmentation device for water treatment comprises a top feed tray, an intermediate oxygenating tank and a bottom oxygenating tank, which are of net cage structure. The bottom of the feed tray is joggled with the top of the intermediate oxygenating tank, the bottom of the intermediate oxygenating tank is joggled with the top of the bottom oxygenating tank, a first aeration device is equipped in the intermediate oxygenating tank, and a second aeration device is equipped in the intermediate oxygenating tank. The first aeration device and the second aeration device are communicated with an oxygenating pump through a first air inlet pipe and a second air pipe correspondingly. Organic spherical cultivation carriers are filled into the intermediate oxygenating tank, and the bottom oxygenating tank is filled with inorganic mineral cultivation carriers. The bioaugmentation device has the advantages that instead of existing bioaugmentation method of directly feeding strains, the device that is good in purification effect, capable of helping nitrifier propagate quickly and less prone to generating secondary pollution is provided. During treatment of culturing water, the aeration devices can supply oxygen for microorganisms, and for bred fish and shrimps etc.

Description

technical field [0001] The invention relates to a biological synergistic device for water treatment. Background technique [0002] my country is one of more than 20 countries with severe water shortages in the world. With the development of industry, the increase of population, the intensification of urbanization and the increase in the use of chemical fertilizers and pesticides, not only a large amount of harmful water bodies have been produced, but also rivers have been seriously polluted and destroyed. The ecological environment affects human survival. However, the traditional water treatment technology consumes a lot of energy and is no longer suitable for the current sustainable development needs of energy conservation and environmental protection. [0003] Regarding water treatment, there are mainly three methods: physical, chemical and biological. Physical methods mainly include adsorption, sedimentation and filtration. The advantages are low operating costs, but the...
