Filtration treatment equipment for circulating water

Abstract

The invention discloses filtration treatment equipment for circulating water. According to the filtration treatment equipment, a separation cylinder is provided with a first water inlet, a first wateroutlet and a drain outlet, a separation plate in the separation cylinder is provided with a separation hole and a discharge port, the bottom of the discharge port is provided with a discharge channel, and the first water outlet is communicated with a water storage zone; a filtration cylinder is obliquely arranged, the filtration cylinder is provided with a second water inlet, a second water outlet and a sewage port, the second water inlet and the first water outlet are communicated with each other through a connecting pipe, the filtration cylinder is internally provided with a rotating cylinder and an arc filter plate, the side wall of the rotating cylinder is provided with a filtering part and a sealing part, the rotating cylinder is internally provided with a water outlet passage communicated with the filtering part; the filter plate and the other side of a side plate are connected with each other to form a sealed filtering cavity, the filter plate is provided with a first filteringhole, the rotating cylinder is provided with a washing part, and the washing part can wash the first filtering hole. The filtration treatment equipment for the circulating water has the advantages that a filter mechanism can be prevented from being blocked, and the filtration efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to circulating water filtration treatment equipment. Background technique [0002] With the continuous development of the economy, the protection of the ecological environment and the rational and effective use of resources have become the focus of people's increasing attention. At present, the environmental pollution in our country is serious. The discharge of industrial wastewater and urban domestic wastewater has caused environmental pollution. At the same time, the excessive exploitation and use of water resources has made our country face a serious water crisis. The comprehensive prevention and control of water pollution has attracted widespread attention from all over the world. Improving sewage treatment technology, increasing treatment efficiency, reducing costs and energy consumption, and recycling sewage after treatment are still important research contents. [00...

AI Technical Summary

Problems solved by technology

However, the use of chemical methods often brings secondary pollution, and the cost of biological treatment is relatively high, and the subsequent separation of heavy metal ions is also relatively complicated. Therefore, the use of physical methods to recycle sewage has become a research direction.

At present, most of the filtration equipment used to remove solid particles and impurities in circulating water by physical methods adopts traditional filter screens, filter elements, etc., or adopts activated carbon adsorption. After a period of filtration, the filter screens and filter elements will be blocked. , or the activated carbon is saturated, and then the filter equipment must be disassembled, and filter elements such as filter screens, filter elements, and activated carbon must be cleaned or replaced before the entire set of filter equipment can restore the filtering function. If the water pollution is serious, the particles and flocs in the sewage More, the replacement will be more frequent, and the filtration speed of the existing filtration equipment is fixed, when the flow of water increases, it cannot meet the requirements of fast filtration
