Circulating filtration treatment equipment for water

Abstract

The invention discloses circulating filtration treatment equipment for water. The filtration treatment equipment comprises a water storage tank, a large-particle filter, a multi-media filter, an alum flocculation tank, an EPS foam bead filter, an activated carbon filter and a circulating flow splitting pump which are sequentially connected through pipelines; if the quality of water treated by the activated carbon filter meets the purified water quality specification, the circulating flow splitting pump is controlled to send the standard water into the purified water tank for storage; if the quality of water treated by the activated carbon filter does not meet the purified water quality specification, the circulating flow splitting pump is controlled to send the nonstandard water into the water storage tank for circulating filtration treatment again. Through the adoption of the filtration treatment equipment, industrial sewage can be effectively purified, circulating filtration of the industrial sewage is realized, the repeated utilization ratio of industrial water is improved, the sewage treatment capacity is relieved, the discharge capacity of the industrial sewage is reduced, water body pollution is reduced, and then considerable economic benefits are achieved.

Description

technical field [0001] The invention relates to circulating water filtering 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, improving treatment efficiency, reducing costs and energy consumption are still important research contents. Existing methods of sewage treatment include traditional physical and chemical methods, as well as new...

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.

Most of the current industrial sewage treatment devices just treat the sewage to t
