Problems solved by technology

[0004] Aiming at the problems existing in existing runoff pollution control and reuse technologies, the present invention proposes a system for collecting, purifying, storing and reusing runoff on the surface of the storage yard. The inflow sewage interception module is used to intercept the large floating and suspended solids in the surface runoff of the storage yard, preventing them from entering the ecological clean ditch to deposit and block the ditch; and laying anti-seepage in the ecological clean ditch and the multi-unit rainwater garden

Embodiment Construction

[0040] The structure and operation process of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] The embodiment of the present invention provides a system for collecting, purifying, storing, and reusing the surface runoff of a railway stockyard, including a stockyard 1, an ecological clean water ditch inflow sewage interception module 2, an ecological clean water ditch 3, and a multi-unit rain garden for reused water 4. Ecological-biological-electrolytic coupling purification module 5 and solar power generation equipment 6.

[0042] Wherein, a plurality of ecological water purification ditch inflow sewage interception modules 2 are arranged around the storage yard 1 , and the runoff of the storage yard 1 flows into the ecological water purification ditch inflow sewage interception modules 2 . The surface runoff in the storage yard 1 enters the inflow sewage interception module 2 of the ecological water purification dit...

Abstract

The invention discloses a railway stockyard surface runoff collecting, purifying, storing and recycling system, which is used for controlling surface source pollution formed by the surface runoff of astockyard. The surface runoff of a stockyard enters an ecological water purification ditch and a reuse water multi-unit rainwater garden through an inflow sewage interception module in sequence, andan ecological- biological-electrolysis coupling purification module is arranged in the ecological water purification ditch and the reuse water multi-unit rainwater garden. The ecological water purification ditch inflow sewage interception module has the functions of intercepting large floating and particle pollutants and filtering and adsorbing ammonia nitrogen to purify surface runoff. The ecological water purification ditch loaded with the ecological-biological-electrolysis coupling purification module and the reuse water multi-unit rainwater garden have the functions of water conveying, purifying, storing and recycling, microorganisms are enriched through natural fiber filler, and an electrolysis system powered by solar energy is arranged to strengthen removal of nitrogen, phosphorus and organic matter. The effluent reaches the reuse water standard in 'The reuse of urban recycling water-Water quality standard for urban miscellaneous water consumption' (GB/T 18920-2002), and the effluent is reused as water for greening and flushing the ground.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a system for collecting, purifying, storing and reusing surface runoff of railway stockyards. Background technique [0002] At present, the non-point source pollution of surface runoff seriously threatens the water ecological environment. The pollutants in the flushing water of the railway yard and the rainwater runoff pose a serious threat to the nearby water environment. Combining with the concept of sponge city, it is of great practical significance to establish a circulation purification and utilization system for the surface runoff of the storage yard that integrates collection, purification, storage and reuse, which can greatly reduce the pollution of the surrounding receiving water and soil. [0003] In recent years, rainwater collection, treatment and utilization systems based on the concept of sponge city have developed ...
