Intelligent rainwater/wastewater purification method and system

Abstract

The invention discloses an intelligent rainwater / wastewater purification method and system. The system comprises an intelligent control device and a purification device, wherein the purification device comprises a wastewater sludge sedimentation tank, a wastewater sludge separation tank, a filtering-stone water-purifying tank, an activated-carbon water-purifying tank, a microbial-bacterium water-purifying treatment tank and a purified-water storage tank. The method provided by the invention can reduce the pressure and the initial investment of urban municipal drainage; urban rainwater are collected and stored for comprehensive utilization, diversified application of purified water obtained after intelligent purification and sludge removal as irrigation water for afforestation, washing water for urban roads, fire protection water for living quarters, water for groundwater recharge and the like is realized, so recovery, purification and reclamation of rainwater are accomplished; and the method can effectively reduce urban heat island effect and improve pollution of a water environment for urban residents.

Description

technical field

[0001] The invention relates to a rainwater / sewage purification treatment system, in particular to a water environment engineering treatment and restoration device integrating rainwater / sewage collection, treatment, and reclaimed water utilization, specifically an intelligent rainwater / sewage purification treatment method and system. Background technique

[0002] With the rapid advancement of my country's new urbanization process, the urban planning and construction land is getting larger and larger, among which residential land, public land, industrial land, storage land, road land and engineering facility land account for nearly 80% of urban construction land, Green land does not exceed 20%, and according to the current 2014 "Outdoor Drainage Design Code GB50014" standard, the runoff coefficient of parks and green spaces is 0.1-0.2, which is relatively small, and the rest of the construction land, especially roads and old urban areas, can reach more than 0.8 ...

Examples

Embodiment

[0059] An intelligent rainwater / sewage purification treatment method, comprising the following steps:

[0060] 1) First, the silt in the rainwater / sewage is gradually precipitated, so that the large particles of silt in the sewage are precipitated, and the surface sewage with a small amount of silt continues to flow into the next step for purification;

[0061] 2) Separation and re-precipitation of the sewage and silt in step 1), the flow rate of the sewage slows down, the sewage with sediment entrained in the bottom layer is deposited and intercepted, and the surface sewage continues to flow into the next step for purification;

[0062] 3) Perform initial purification treatment on the sewage in step 2), the sewage is filtered through the filter stone, the sediment is blocked on the surface of the filter stone, and the treated sewage continues to flow into the next step for purification treatment;

[0063] 4) Filter and purify the sewage after the purification treatment in ste...
