Description

Fish pond landscape water biochemical filter

technical field

The utility model relates to a filter device, in particular to a fish pond landscape water biochemical filter.

Background technique

Most of the existing water bodies such as fish ponds and waterscapes do not have filtering devices, and they will soon become turbid, green and smelly, and the fish they raise will often die, so they have to change the water and wash the pond frequently, which consumes a lot of manpower and material resources. Some pisciculture enthusiasts have to build a very large filter tank while building the tank, and fill various filter materials therein for circulating filtration. The filter materials in the existing filter media are mostly ceramic rings, crushed coral, quartz sand, anthracite and other filter materials. The use of such filter materials has low filtration accuracy, small dirt holding capacity of the filter bed, and low filtration speed. Later, fiber synthetic Filter material, although this kind of filter material can make up for the defects of traditional granular filter material, but because of the small difference in specific gravity with water, the cleaning effect of the synthetic fiber formed body filter material is poor, and the fiber is easy to lose during backwashing. There are also a small number of pond filters that use sponges and the like as filter materials on the market, but no matter whether it is a brick-concrete filter pond or a commercially available pond filter, it will be blocked by the filtrate very quickly, and it needs to be manually cleaned regularly.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, concrete structure and working process of the present utility model are described.

As shown in Figure 1, a fish pond landscape water biochemical filter, the filter is a sealed barrel-shaped sealed container. The bottom of the sealed container is provided with a water inlet pipe 2, a sewage pipe 5 and a backwash pipe 4, and the top is provided with an outlet pipe 3, and the upper layer of the container is provided with a suspended biochemical filter material 1 and beneficial bacteria, specifically a suspended biochemical filter material 1. MBBR filler is used, and the outlet pipe 3 is provided with an ultraviolet sterilizing and algae-killing lamp 6. Specifically, the MBBR filler is a biochemical filter material that can be suspended in water. When filtering, the filter material floats to form a stable filter layer. Finally, it flows out from the outlet pipe 3 on the top, which is different from the usual fluidized bed filtration. Since the filter layer is stable, the gaps between the filter material particles and the chamber inside the filter material will intercept and hold the solid impurities in the water, thereby realizing Physical filtration. At the same time, when the filter is started, beneficial bacteria such as nitrifying bacteria are added. The bacteria will attach to the outer surface of the filter material to form a biofilm. The biofilm decomposes nitrogen and ammonia in the water and other harmful substances that deteriorate the water quality, preventing For the eutrophication of the water body, the outlet pipe 3 of the filter is equipped with an over-flow ultraviolet sterilizing and algae-killing lamp 6 to sterilize the filtered water, thereby keeping the water body always clear and suitable for the growth of fish and other organisms.

After the filter works for a certain period of time, more and more impurities will be intercepted and retained by the filter. At this time, the water pump controlled by the time controller will stop running, and an electromagnetic air compressor will compress the air from the bottom of the filter to backwash the pipe. Pump to form a large number of rising air bubbles, these bubbles will make the filter material suspended on the upper part of the filter roll, the impurities staying on the filter material will be separated and fallen off, and the filter material will be "air washed". After backwashing for a period of time, install The solenoid valve of the sewage pipe at the bottom of the filter is opened to discharge the sewage. After the backwashing and sewage discharge are completed, the air compressor stops, the sewage solenoid valve is closed, and the water pump is restarted to continue the filtering work. For large filters, Venturi tube air-water combined backwashing is used, and compressed air and high-pressure water flow will be injected into the backwashing pipe to form a stronger impact on the filter material.

Separation of sediment and suspended solids in the water and the cultivation of beneficial bacteria in the filter material, the decomposition of ammonia nitrogen compounds in the water body, through continuous circulation and filtration, that is, the pool water is pumped into the filter, and then returned to the pool after filtration, continuous circulation, to maintain The water body is always clear and the water quality is good. The time controller controls the automatic backwashing and sewage discharge, and the filter does not need manual cleaning for many years.

The above descriptions are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Without departing from the scope of the technical solution of the utility model, the technicians of this patent may use the technical content of the above hints to make some changes or modify them into equivalent embodiments with equivalent changes, but all those that do not deviate from the technical solution of the utility model Content, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still belong to the scope of the utility model solution.
