Problems solved by technology

[0003] At present, my country's tap water plants generally adopt conventional water purification treatment processes, which are difficult to effectively remove organic matter, ammonia nitrogen and other pollutants in raw water. Although advanced treatment can effectively improve the quality of factory water, the cost is high, and some water plants have to use pollution The water source is used as drinking water and other water sources, drinking water is not safe

Abstract

The invention discloses a device and method for restoring a polluted water source through a multi-media bio-filter. The device is used for restoring polluted water of an upstream river way of a river type water source. A dam is arranged in the upstream river way. The device is arranged on the outer side of the dam. The device comprises a tower layer frame, carrier packing layers and a water collector. Water distributors are arranged at the upper end of the tower layer frame and used for introducing the polluted water source in the dam into the tower layer frame. The multiple carrier packing layers are arranged in the tower layer frame from top to bottom. The water collector is arranged at the lower end of the tower layer frame, collects the water source filtered through the carrier packing layers and drains the water source to a downstream river way. By the adoption of the device and method for restoring the polluted water source through the multi-media bio-filter, the water quality of the water source can be improved, the water body of the water source can be restored, the functions of the water source can be restored, and the safety of drinking water can be guaranteed.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a device and method for repairing polluted water sources with a multi-media biological filter bed. Background technique [0002] With the rapid development of industrialization in our country and the continuous expansion of cities, the pollution of water quality by pollutants discharged by people in the process of production and life has intensified. The organic pollutants and ammonia nitrogen in water are increasing, and the degree of pollution is becoming more and more serious. my country's water resources are short, and the quality of drinking water sources is deteriorating day by day. The restoration of water sources, the improvement of water quality and safety pretreatment technology have become an important and urgent research topic. [0003] At present, my country's tap water plants generally adopt conventional water purification treatment processes, which are difficult ...
