Description

Technical Field

[0001] The invention belongs to the field of water treatment and relates to a pressure-matching precision-adjustable high-efficiency fiber filter and a working method thereof. Background Art

[0002] As an effective pollutant removal process, filtration is widely used in various water treatment projects. Compared with traditional granular filter media, fiber filter media has the advantages of high adsorption, high specific surface area, high porosity, and near-ideal filtration along the filter layer, and has been widely used in various fields of life. In order to give full play to the filtration advantages of fiber filter media, fiber filters of various forms have appeared in recent years. Different fiber filters have their own advantages and disadvantages in the way of applying fiber filter media. Fiber ball and comet filters, due to the presence of the hard core in the middle and the fiber filter media entangled into balls, will cause uneven distribution of water flow resistance, easily cause "wall flow" and "channel flow" phenomena, and incomplete backwashing. Fiber bundle filters include capsule fiber filters, PCF fiber filters, and skateboard fiber filters. The operation of capsule filter is complicated and the capsule is easy to break, which affects the normal filtration. The amount of fiber filter material in PCF fiber filter is relatively small, so the filtration cycle is short and the backwashing is frequent. The slide plate fiber filter simplifies the equipment structure and improves the water utilization rate of the filter column cross section. However, the head loss of the filtrate when flowing through the sliding orifice plate has little effect on the actual thrust of the slide plate (at 2% opening rate and 30m / h filtration speed, the head loss is only 25kg / m 2 ), the compression effect on the fiber layer is extremely limited, the filtration accuracy is low, and the sliding orifice plate is prone to jamming, affecting stable operation. Summary of the invention

[0033] As is known, the high-efficiency fiber filter is a pressure-type fiber filtration device with advanced structure and excellent performance. The following is a detailed introduction to the high-efficiency fiber filter: The high-efficiency fiber filter is a new type of energy-saving water purifier developed based on the principle of fluid mechanics after years of practice. It is a continuous filtration device integrating flocculation, clarification and filtration. It uses a new type of bundled soft filler, that is, fiber as the filter element. The fiber section length is generally 3540mm, the bundle section diameter is usually 3.84.0mm, and the filter material diameter can reach tens of microns or even several microns. These fibers are arranged in a staggered manner to form a complex micro-pore network, thereby achieving the capture and filtration of impurities in the fluid. Features and advantages: High filtration accuracy: The high-efficiency fiber filter has a removal rate of up to 100% for suspended solids in water. When the turbidity of natural water treated with good coagulation is 20NTU, the turbidity of the filtered water can be controlled to below 2NTU. Fast filtration speed: Its filtration speed is generally 30m / h, which is 3 to 5 times that of traditional filters, and can reach a maximum of 50m / h. At the same time, the filtration speed can reach 45 meters / h. Large sewage interception capacity: Its sewage interception capacity is generally 510kg / m 3 , which is 24 times that of traditional filters. Strong adjustability: Parameters such as filtration accuracy, interception capacity, and filtration resistance can be adjusted as needed. Small footprint: To produce the same amount of water, the footprint of the high-efficiency fiber filter is only 1 / 3-1 / 2 of that of the traditional filter. Low cost per ton of water: Compared with traditional filters, the cost per ton of water for high-efficiency fiber filters is lower. Low backwashing water consumption: The backwashing water consumption is only 1-3% of the cycle water production. Under normal circumstances, raw water can be used for backwashing. Long service life: The equipment does not need to replace the filter element. After the filter element is contaminated, it can be easily cleaned to restore its filtration performance. The filter element life is not less than 10 years.
