Positive pressure water treatment device and water treatment system

Abstract

The invention discloses a positive pressure water treatment device and a water treatment system. The positive pressure water treatment device comprises a filter barrel, the filter barrel comprises a barrel body, an upper cover and a bottom cover, an opening is formed in the upper portion of the filter barrel, filter materials are arranged in the barrel body, a water outlet pipe L3 is arranged at the top of the upper cover, a water pump is arranged in the bottom cover, a water inlet is formed in the bottom of the barrel body, water in the bottom cover is conveyed into the barrel body through the water inlet by the water pump, and the water pump is provided with an air inlet pipe. The water treatment system comprises a filter tank, the middle of the filter tank is isolated by a separation wall, a distance is reserved between the separation wall and the bottom of the filter tank, the positive pressure water treatment device is placed on one side of the separation wall, a sewage tank is arranged on the other side of the separation wall, and sewage in the sewage tank flows to the periphery of the bottom cover of the positive pressure water treatment device from the lower side of the separation wall and enters the bottom cover from through holes. Oxygen is allowed to enter the device, so that nitrifying bacteria in the filter barrel rapidly breed, and pollutants such as ammonia and nitrite in the sewage are rapidly treated.

Description

technical field [0001] The invention relates to a positive pressure water treatment device and a water treatment system, belonging to the technical field of filtration. Background technique [0002] The nitrifying bacteria culture device is an important part of the industrial sewage treatment system. However, the current digestive bacteria culture devices generally have the problems of low efficiency, insufficient dissolved oxygen, and difficult cleaning. This greatly limits the application of nitrification systems in sewage treatment systems. Therefore, chemical methods are commonly used in industrial production instead of biological methods to treat pollutants such as nitrite, but chemical methods are more environmentally friendly than biological methods, and the use of chemicals is minimized. [0003] The digestive bacteria cultivation device is also an important purification equipment in the family aquarium equipment. At present, there is no reasonable and effective fami...

Problems solved by technology

[0004] The traditional bottom filtration system relies on the difference in water level to generate water flow. The disadvantage is that the water flow is small, so a large amount of filter material needs to be placed to achieve the ideal filtering effect, and because the filter material lacks oxygen, the nitrifying bacteria necessary to filter ammonia and nitrite Difficult to reproduce in large numbers and thus do not filter well

Filtration effect can be guaranteed when a large amount of filter material is placed, but this will take up a lot of space

[0005] Another kind of filtering equipment is an external filter barrel, which sets the physical filter cotton and filter material in the filter barrel. The advantage is that the structure is compact, but the disadvantages are relatively obvious: 1. The filtering effect is poor, and the filter barrel is closed. Due to the extreme lack of oxygen As a result, it is difficult for nitrifying bacteria to reproduce, and it also consumes dissolved oxygen in the water, competing with fish for oxygen

2. Cleaning is extremely cumbersome. Since the physical filter material is set in the barrel, the filter barrel must be opened when cleaning, which is extremely inconvenient to operate, and the cycle must be stopped when cleaning, and all nitrifying bacteria will die within 3 minutes due to lack of oxygen.
