Method for catching suspended matters in water body and applied to water pollution control

Abstract

The invention discloses a method for catching suspended matters in a water body and applied to water pollution control, belonging to the field of water pollution control. According to the method, a secondary precipitation step is added into in a traditional wastewater purification process, and a permeable core for refined filtration is arranging at a water outlet of a secondary precipitation tankso as to facilitate further purification of wastewater; an oil suction head is arranged in the permeable core for refined filtration, and water flow in the oil suction head has impact pressure on theoil suction head, so oil drops are guided and conveyed step by step and are absorbed to a proper position in a centralized manner for centralized treatment, and emulsified oil drop substances in the water flow can be efficiently removed; and oil obtained centralized treatment is removed by conveniently and locally replacing an oil absorption rods through the disassembly and assembly of a filter screen core, so the service life of the permeable core for refined filtration can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of water pollution control, and more specifically relates to a method for fishing suspended matter in a water body for water pollution control. Background technique [0002] With the increase of population, the rapid development of social economy and the acceleration of urbanization, the problem of water pollution in China is becoming more and more serious. my country's per capita water resources only reach 1 / 4 of the world's per capita water resources, and about half of the cities in the country are short of water. However, the deterioration of water quality has made the problem of water shortages worse. Rivers and lakes in our country are generally polluted, most of the lakes have different degrees of eutrophication, and the main water system is obviously polluted. In the country's seven major water systems (Pearl River, Yangtze River, Yellow River, Huaihe River, Liaohe River, Haihe River, and Songhua River), there...

Problems solved by technology

[0005] However, the existing fishing methods for suspended solids in water pollution control are relatively simple, and it is difficult to remove the emulsion oil droplet in the wastewater in a targeted manner, which makes it difficult to treat the emulsion oil droplet in a reasonable manner when it is discharged, resulting in the discharge of water sources into the external environment, resulting in the enrichment of oxygen in the water body
