A storage and purification system

Abstract

The invention discloses a regulation, storage and purification system, wherein the regulation, storage and purification system comprises an interception barrel floating in a water body, a water storage bag, a fluidized bed sewage treatment device and an artificial floating island filter belt, the retention barrel and the water storage bag The water inlet of the fluidized bed sewage treatment plant is connected to the water storage bag to receive sewage and intercept floating objects. The water storage bag is used to store sewage and settle sediment. The fluidized bed sewage treatment device is connected to the water storage bag through pumping equipment to decompose organic matter and remove nitrogen and phosphorus. The water inlet of the artificial floating island filter belt is connected to the water outlet of the fluidized bed sewage treatment device, and the water outlet of the artificial floating island filter belt is used to connect to the receiving water body. Therefore, it can effectively solve the problem of surface water pollution caused by the overflow of combined pipe network or initial rainwater in densely developed areas or old urban areas, and does not occupy the ground space, but uses the volume of surface water to collect, store and purify sewage , Efficiently remove suspended solids, sediment, organic matter, nitrogen and phosphorus and other nutrients to ensure continuous cleanliness of surface water.

Description

technical field [0001] The invention relates to the field of water environment treatment and ecological restoration, in particular to a storage and purification system. Background technique [0002] With the development of the national economy and society, the degree of black and odorous water bodies in the country has become a major problem that restricts my country's social and economic development and affects its image and ecological security. According to statistics, more than 80% of urban rivers in my country are polluted, and seasonal and perennial water black and odorous phenomena appear. According to the 2014 China Environmental Status Bulletin, among the 968 state-controlled surface water testing sections in 423 major rivers and 62 key lakes (reservoirs) across the country, 36.9% of the water sections exceed Class III, and the main pollution indicators are chemical oxygen demand, Total Phosphorus and Total Nitrogen. [0003] At present, most areas in China have st...

AI Technical Summary

Problems solved by technology

At present, these two pollution control methods are still difficult problems. Common methods include changing the combined drainage network into a separate drainage network, expanding the interception multiple of pipelines, building land storage tanks, and building deep storage tanks. These measures may involve It is often difficult to implement problems such as demolition, or huge project volume, or large land occupation, or difficult construction, or huge investment in areas where land development is intensive and there is no usable space
