Problems solved by technology
[0003] Due to the interception and adsorption principle of the filler inside the device, when the device has been in operation for three to six months, the sediment, impurities, suspended solids, etc. retained by the fine particle size filler will gradually settle and accumulate, directly affecting the microbial degradation effect of the device, resulting in purification The effect becomes worse, and the water quality of the effluent does not meet the drinking water standard.
When cleaning the biological slow filter device, it is necessary to elutriate the small particle size filler in the upper part, and clean up the impurities, suspended solids and chemical substances in the device. The operation is complicated, and the workload is heavy when the filler is moved inside and outside the device. Waste of manpower and time, extremely inconvenient

The invention discloses a biological slow filtration apparatus with a backflushing device, comprising a transparent housing. The upper end of the transparent housing is opened; the middle of the innerbottom of the transparent housing is fixedly connected to the lower end of a transparent fixing tube; a coarse filter device and a fine filter device are mounted on the lateral side of the transparent fixing tube; the coarse filter device is arranged above the fine filter device; the lateral side of the transaprent fixing tube is provided with a first hole, a second hole and a third hole. The biological slow filtration apparatus is complex to operate and saves manpower and time; the coarse filter device divides fine filling material and coarse filling material, filling material mixing causedby water flow carrying a fine filler layer into the coarse filling material is avoided, and filtering effect is ensured; an insert tube allows a user to wash the coarse filter device or the fine filter device independently. The biological slow filtration apparatus is simple to operate and enables a user to work more efficiently.
Description
technical field [0001] The invention relates to the technical field of biological slow filtration, in particular to a biological slow filtration device with a backwashing device. Background technique [0002] The existing biological slow filter is composed of the device's operating shell and internal fillers of different particle sizes. The impurities, suspended solids and chemical components contained in the water are filtered through the fillers inside the device to achieve the effect of purifying water. The device passes different particle sizes during operation. The interception and adsorption of diameter fillers and the chemical degradation of microorganisms reduce harmful components to a drinkable level. This device is very suitable for the promotion of small-scale decentralized drinking water treatment in rural areas. [0003] Due to the interception and adsorption principle of the filler inside the device, when the device has been in operation for three to six months...
