A rainwater resource treatment device and method

Abstract

The invention belongs to the technical field of the rainwater reclamation, and specifically provides a processing device for rainwater reclamation. The processing device for rainwater reclamation comprises a storage pond, and is characterized in that an exit of the storage pond is connected with an entrance at the upper part of a number 1 constructed wetland through a first connecting pipe. An exit at the bottom of the number 1 constructed wetland is connected with an entrance at the bottom of the number 2 constructed wetland through a second connecting pipe. An exit of at the upper part of the number 2 constructed wetland is connected with an entrance of a PE-ACF composite filter filtering unit through a third connecting pipe. An exit the PE-ACF composite filter filtering unit is connected with a drain pipe. The processing device for rainwater reclamation has the advantage of achieving high-efficient reclamation of rainwater on the ground.

Description

technical field [0001] The invention belongs to the technical field of rainwater resource utilization, and in particular relates to a treatment device and method for rainwater resource utilization. Background technique [0002] The karst area in Southwest my country is rich in surface water resources, and the annual precipitation is about 800-1200 mm, but the temporal and spatial distribution is uneven, and the surface rainwater resources are rapidly seeped and lost, resulting in abundant groundwater resources but lack of surface water, resulting in engineering and seasonal water shortages. question. [0003] In response to the above problems, in recent years, the country has built a large number of water cellars in the karst rocky mountainous areas of southwest China, which has effectively alleviated the water shortage problems of drinking water for humans and animals in dry seasons and irrigation in dry land in karst mountainous areas. SS) and microbial pollution (the tota...

Problems solved by technology

[0002] The karst area in Southwest my country is rich in surface water resources, with an annual precipitation of about 800-1200mm, but the distribution of time and space is uneven, and the surface rainwater resources are rapidly seeped and lost, resulting in abundant groundwater resources but lack of surface water, resulting in engineering and seasonal water shortages. question

[0003] In response to the above problems, in recent years, the country has built a large number of water cellars in the karst rocky mountainous areas of Southwest China, which has effectively alleviated the water shortage problems of drinking water for humans and animals in dry seasons and irrigation in dry land in karst mountainous areas. SS) and microbial pollution (the total number of bacteria exceeding the standard) caused water quality-type water shortages, which seriously endangered the drinking water safety of local people and animals
