Embodiment 1

[0035] There is a rainwater regulation and storage space 2 covering an area of ​​200m2, and the rated flow rate of its outlet water pump 4 is 20m3 / h. Add 200kg iron-carbon filler 3 to the bottom of the rainwater regulation and storage space 2, install the tank body 5 filled with 3m activated carbon to the iron-carbon recovery device, and then complete the transformation of the rainwater regulation and storage space 2 using the method provided by the invention, and the water will be discharged The water pump 4 pumps the rainwater treated by the iron-carbon filler 3 into the tank body 5, and the support mesh plate 8 in the tank body 5 erects the iron-carbon filler 3 on the upper side of the support mesh plate 8, and the rainwater is on the upper side of the iron-carbon filler 3 The liquid level is the oxidation reaction layer 9, and the rainwater is further purified in the oxidation reaction layer 9 and flows out from the outlet pipe 7, and carbon powder and iron-containing alum ...

Embodiment 2

[0037] There is a rainwater regulation and storage space 2 covering an area of ​​160m2. The rated flow rate of the outlet water pump 4 is 12m3 / h. A constructed wetland covering an area of ​​20m2 and a filler layer thickness of 0.8m is arranged at the outlet. Add 240kg of iron-carbon filler 3 to the bottom of the rainwater regulation and storage space 2. In this embodiment, the iron-removing filler 12 in the wetland pool body 10 is composed of 40% manganese sand and 60% activated carbon. The method for the transformation of the rainwater storage space 2.

Abstract

The invention discloses a rainwater regulation and storage space water body purification method which comprises a rainwater regulation and storage space, the rainwater regulation and storage space is provided with a rainwater inlet, an iron-carbon filler is arranged at the bottom of the rainwater regulation and storage space, rainwater is stored on the upper side of the iron-carbon filler, and a water outlet pump is further arranged on the iron-carbon filler. The outlet end of the water outlet pump is connected with an iron-carbon recovery device, and iron removal filler is arranged in the iron-carbon recovery device. The device has the advantages that the water body can be sterilized and disinfected through the iron-carbon filler, and energy consumption input is not needed when the iron-carbon filler plays a role in the water body. Power required by product recovery is provided by a water outlet pump of the rainwater regulation and storage space without additional energy consumption input, so that the energy consumption input is small; backwashing in product recovery can be automated through an electrical control system, labor input is low, and iron-carbon filler and iron removal filler are low in price. Therefore, the system has the advantages of thorough black and odor treatment, low construction cost and low operation and maintenance cost.

Description

technical field [0001] The invention relates to the field of sponge cities, in particular to a method for purifying water in a rainwater regulation and storage space. Background technique [0002] In the sponge city project, the water body in the rainwater storage space is often black and smelly. The reason is that the organic matter and nutrient salt brought in with the initial rainwater and non-initial rainwater are in the anaerobic environment and the role of spoilage microorganisms in the rainwater storage space. Produce black odor. If it is not treated and controlled, it will affect the utilization of stored rainwater, and even cause secondary pollution to the surrounding surface water. The existing treatment methods include: discarding and purifying the initial rainwater, filtering and disinfecting the effluent from the rainwater storage space, performing circular biological treatment on the water body in the rainwater storage space, and performing aeration treatment ...
