Ecological chain cellar and treatment method thereof

Abstract

The invention discloses an ecological chain cellar and a treatment method thereof. The ecological chain cellar comprises a cellar arranged between a mountain slope and a dam, wherein a platform is arranged on the surface of the cellar; a sealed space is formed between the platform and the mountain slope and the dam; a sludge treatment pond and an organic fertilizer workshop are arranged on the upper surface of the platform; a main sewage pipeline and a suspended solid isolation device are arranged at the top of the sludge treatment pond from top to bottom; the main sewage pipeline is communicated with municipal sewage. Sewage sequentially passes through the sludge treatment pond, a biochemical treatment pond and a series of filtering devices, is completely subjected to solid-liquid separation and then fed into the cellar, and the water is used for agricultural irrigation after gas production. The ecological chain cellar manner is used for treatment of municipal domestic wastewater, wastes are changed into valuable materials to realize recycling, organic fertilizer, biogas production, agricultural irrigation and the like are realized, secondary pollution is eliminated, and the ecological chain cellar is environment-friendly and has true recycling significances for changing the wastes into valuable materials.

Description

technical field [0001] The invention relates to a sewage treatment device and a treatment method, in particular to an ecological chain cellar and a treatment method. Background technique [0002] In recent years, the speed of my country's economic development has risen in a straight line, and the GDP has been in a state of steady growth, which shows that people's living standards are constantly improving. However, for the utilization of water resources, people generally have such a deep-rooted idea of ​​inexhaustibility, which leads to increasing waste and pollution of water resources. However, the development of urban industrial production has increased the use of water resources, so the supply of fresh water resources has been in short supply. In addition, the urban industrial development has caused the sewage problem to increase. The urban sewage problem has gradually become a threat to the normal development of the city and affects the urban ecology. Prime factor. [0...

AI Technical Summary

Problems solved by technology

[0005] The ecological chain cellar contains the above-mentioned 1st, 2nd, and 3rd-level treatment methods of sewage treatment, but none of them can meet the treatment requirements of urban domestic wastewater. The main reason is that these sludges contain a large amount of organic matter and pathogens, and are easy to rot and smell It is easy to cause secondary pollution, and the task of eliminating pollution has not been completed

If the sludge is not treated, the sludge will have to be discharged with the treated effluent, and the purification effect of the sewage plant will be offset
