Buried integrated rainwater recycling system and construction method thereof

Abstract

The invention discloses a buried integrated rainwater recycling system and a construction method thereof. The buried integrated rainwater recycling system comprises a rainwater collecting pool, a safety flow dividing well and a rainwater recycling and utilizing device, and the rainwater collecting pool is correspondingly connected with the safety flow dividing well and the rainwater recycling and utilizing device; the rainwater collecting pool sequentially comprises vegetation soil, a medium sand protection layer, a water storage module framework, composite waterproof geotechnical cloth, a concrete foundation and plain soil from top to bottom; a microbial carrier ball and an aeration device are arranged in the water storage module framework, and a microbial flora is adhered to the microbial carrier ball; and a sewage discharging well is arranged in the water storage module framework, a rainwater lifting pump is arranged in the sewage discharging well, and the rainwater lifting pump is connected with the rainwater recycling and utilizing device through a pipeline. The rainwater recycling efficiency is improved, urban inland inundation is relieved, and the ecological environment is protected.

Description

Technical field [0001] The present invention relates to an integrated buried rainwater recovery system and construction methods, it belongs to the field of environmental protection. Background technique [0002] Due to natural rainfall with low hardness, less pollution, etc., so it is becoming an increasingly important topic in terms of reducing urban storm water hazards, to develop water-use. Rainwater is collected and certain processing, except for watering crops, groundwater recharge, but also for the landscape environment, green, car wash water, road washing, cooling water supplement, flushing and other non-domestic water use. [0003] Rainwater harvesting is a traditional city after rain fell on the ground, in part through the ground to replenish groundwater infiltration, infiltration can not or failed to infiltration of rainwater, collected through the ground into the rain and sewage system, then upgrade storm sewer or discharge by pump into the river, namely the traditiona...

AI Technical Summary

Problems solved by technology

However, with the process of urbanization, more and more permeable surfaces are covered by impermeable surfaces (roads, roofs, grounds, etc.), which affect the natural cycle of rainwater infiltration, and the rain and sewage diversion system is not enough to quickly remove the surface. Water, exacerbated the risk of urban waterlogging, rainwater runoff, loss and waste of rainwater resources, ecological environment damage and other problems
