Manufacturing method of rainwater purification device

Abstract

The invention provides a manufacturing method of a rainwater purification device. The rainwater purification device consists of a rainwater collection container and a leakage screen, wherein the upper end of the rainwater collection container is funnel-shaped; the leakage screen is obliquely arranged in the funnel; the lower end of the funnel is vertical barrel-shaped; the oblique leakage screen is uniformly placed in the barrel-shaped container; one end of the placed leakage screen is provided with a movable switch; the inclination angle of the leakage screen on the rainwater collection container is 60 degrees; and the inclination angle of the leakage screen at the lower end of the funnel is 45 degrees. Rainwater can be fully filtered by the structure.

Description

technical field [0001] The invention relates to a purification device, in particular to a manufacturing method of a rainwater purification device. Background technique [0002] my country's total water resources are 2,812.4 billion m3, of which river runoff is 2,711.5 billion m3, less than Brazil, the former Soviet Union, and Canada, ranking fourth in the world. But my country's per capita water volume is only 2350m3, which is only 27% of the world's per capita water volume. According to the 1990 population statistics of 149 countries, the per capita water consumption is ranked from most to least, and China ranks 110th. The average amount of water per hectare of cultivated land is 27867m3, which is about 3 / 4 of the world. It can be seen that according to the amount of water per capita in my country and the amount of water per unit area of ​​cultivated land, my country is a country with relatively poor water resources. Due to the rapid development of industry, a series of ...
