Abstract

The invention discloses a sponge city water treatment method. The method comprises the following steps that rainwater and sewage are introduced into a sediment separator of a sponge city integration system; sediment and water are separated by the sediment separator, clean water after separation is introduced into a first water treatment chamber and precipitated, the clean water acquired after being precipitated is introduced into a second water treatment chamber and a third water treatment chamber in sequence, and water purification treatment is conducted on the clean water in the third water treatment chamber through a water treatment machine; the clean water after water purification treatment is introduced into a water storage tank for storage and use in future; the sewage after separation by the sediment separator flows into a flood discharge drain pipe via a sewage pipe and is discharged through the flood discharge drain pipe; the water in the third water treatment chamber overflows to a shallow channel through an overflowing device, then flows into a deep channel through an infiltration well, and finally flows into the flood discharge drain pipe for flood discharging through the deep channel. According to the sponge city water treatment method, rainwater and sewage can be transformed into domestic water efficiently and in a environmentally friendly way, flood discharge can be conducted fast, and the method has a good flood discharge effect and universal applicability.

Description

technical field [0001] The invention relates to the technical field of water storage and utilization, in particular to a water treatment method for a sponge city. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] To build a sponge city, coordinate the use of natural ecological functions and artificial intervention functions, effectively control rainwater runoff, and realize the urban development mode of natural accumulation, natural infiltration, and natural purification, which is conducive to restoring urban water ecology, conserving water resources, and enhancing urban waterlogging prevention capabilities. Expand eff...
