Problems solved by technology

Filtration treatment requires multiple cycles, so the filtration flow rate is large and the energy consumption is high. There is also a large-scale equipment with a huge filtration area that will be limited by the restrictions of the filter medium, equipment casing and installation site. Investment in large-scale sewage filtration And the cost of use is very high, so there is no report on the large-scale use of the above-mentioned filter equipment for cyanobacteria sewage treatment
[0007] The existing gill filter, vibrating screen, is a fast and effective cross-flow filtration equipment. It uses a flat-plate filter element above the horizontal surface, which can achieve a large concentration of filtration and removal of cyanobacteria without circulation. However, the filtered water must be completely pumped out of the water body to reach the macro-installed filter screen equipment on the water surface. The lift is high, and it is impossible to use the kinetic energy of natural or artificial natural water flow in lakes and rivers or the kinetic energy of artificial power to push the water flow to filter. In addition, only flat filter components are used on the water surface, so that the filter screen of the equipment can bear less filtration pressure, and it is impossible to increase the filtration pressure and increase the water output per unit area. When the filter mesh is smaller, the filter The water output is small, which limits the improvement of equipment filtration accuracy and filtration efficiency

Abstract

The invention relates to a method for filtering and separating suspended maters from water and a filtering device used in the method. According to the concrete technology, a filter screen of the filtering device is directly arranged in water flow in a water flow channel; the included angle a is formed between the filtering surface of the filter screen and the water flow direction of the surface of the filtering surface, wherein the included angle a can be an acute angle between 0 and 70 DEG or an obtuse angle between 110 DEG C and180 DEG; and the filter screen of the device and different water flow channels form different cross flow filtering systems. The method and device provided by the invention can be widely applied to lake blue-green algae, sewer liquid dung, sewage treatment plants and vegetable drug extraction.

Description

technical field [0001] The invention relates to a physical separation method. The method is specifically that the filter screen of the device is installed at a fixed position in the water flow or in the water body in different water flow channels to form a cross-flow filtration system, especially a device that can The filter screen is placed in the water flow or water body of the water flow channel of the natural water body or the artificial facility to form a large-scale cross-flow filtration system, which uses the natural kinetic energy of the water flow or artificial power to promote the flow energy of the water as the water intake of the cross-flow filtration system and overcomes the resistance of the filter screen The main driving force for filtration is that when the water flows through the filter screen installed in the system, the clear water percolates through the filter screen or is removed by the pushing flow, while the suspended matter in the water body is intercept...
