Description

Circulating water filtering device

Technical Field

The utility model relates to a circulating water filter equipment.

Background

The water pollution is mainly caused by pollutants generated by human activities and comprises four major parts, namely mine pollution sources, industrial pollution sources, agricultural pollution sources and living pollution sources.

The industrial wastewater is an important pollution source of a water area and has the characteristics of large quantity, wide area, complex components, high toxicity, difficult purification, difficult treatment and the like. According to the data of Chinese water resource bulletin in of 1998, the method comprises the following steps: in this year, the total amount of national wastewater discharge is 539 hundred million tons (excluding direct current cooling water), wherein the industrial wastewater discharge amount is 409 hundred million tons, and accounts for 69%. In fact, the amount of sewage discharged far exceeds this number, because the amount of industrial sewage discharged by many rural enterprises is difficult to count.

The agricultural pollution sources comprise livestock manure, pesticides, chemical fertilizers and the like. In the pesticide sewage, the contents of organic matters, plant nutrients and pathogenic microorganisms are high, and the contents of pesticides and chemical fertilizers are high. China does not carry out agricultural monitoring at present, and relevant data show that 110.49 million tons of pesticides are used each year on 1 hundred million water-polluted hectares of cultivated land and 220 million hectares of grassland. China is one of the most serious countries in the world with water and soil loss, and the annual surface soil loss is about 50 hundred million tons, so that a large amount of pesticides and fertilizers flow into rivers, lakes and reservoirs along with the surface soil, and the nitrogen, phosphorus and potassium nutrient elements which flow away along with the surface soil cause 2/3 lakes to be harmed by eutrophication pollution of different degrees, algae and other organisms are abnormally propagated, the transparency of a water body and dissolved oxygen are changed, and the water quality is deteriorated.

The mine environmental pollution refers to the influence and harm of various factors on the environment in the process of mining. The waste water is mainly pit drainage, leaching water generated by ores and waste rock piles, mine industry and domestic wastewater, ore dust, smoke dust discharged by fire coal, SO2, radiation of radioactive substances and the like, and a large amount of harmful substances are contained in the waste water, SO that the mine environment and the human health are seriously harmed.

The domestic pollution sources mainly comprise various detergents, sewage, garbage, excrement and the like used in urban life, most of the domestic pollution sources are nontoxic inorganic salts, and domestic sewage contains more nitrogen, phosphorus and sulfur and more pathogenic bacteria. According to the survey, the discharge amount of domestic sewage in 1998 is 184 hundred million tons. About 1/3 industrial wastewater and more than 90 percent of domestic sewage are discharged into water areas without treatment in China every year, among 1200 rivers monitored in China, 850 rivers are polluted at present, and more than 90 percent of urban water areas are polluted, so that a plurality of river reach fishes and shrimps are extinct, and the rivers meeting the national first-level and second-level water quality standards only account for 32.2 percent. Pollution is progressing from the shallow to the deep layers, groundwater and sea water in the near sea are also being polluted, and water that we can drink and use is being decreased unknowingly.

The polluted water area can be restored only after long-time ecological restoration, and the manpower, material resources and financial resources consumed during restoration are huge.

Aiming at small branch pollution, a circulating water filtering device which can realize filtering of pollutants in water by using a circulating water pumping mode is designed.
