AI Technical Summary

Technical Problem

The foul odor gas produced by sewage treatment plants during the treatment process is difficult to effectively remove. The traditional odor treatment methods have the limitations of high investment, high operating fees or low investment, and low operating fees, making it difficult to achieve high standards and meet high standards emissions.

Method used

A targeted denitrification and sulfur removal biological treatment system based on the bacteria and algae symbiosis system is adopted, and a combination design of nitration pool and green plant purification pool is designed. The partition plate and aeration device are used to promote short-range nitration and denitrification reaction, screen high-quality bacteria, and overflow is irrigated into the green plant purification pool. The algae species work together with the plant root system to purify gas and overflow.

Benefits of technology

It realizes efficient removal of foul odor exhaust gas in sewage treatment plants, effectively eliminates odors, makes full use of nitrogen to promote plant growth, and at the same time improves the efficiency and stability of the biological treatment system.

Abstract

According to the system for treating the foul smell of the sewage treatment plant based on the algal-bacterial symbiotic system, the partition plates in the nitrification tank are utilized to form a plurality of internal circulation cells to promote short-cut nitrification and denitrification reaction, high-quality flora is screened out from the nitrification tank, and then top overflow of the high-quality flora serves as irrigation water to be supplied to the green plant purification tank; and the gas generated by overflow and the nitrification tank is purified through mutual cooperation with algae species in the green plant root system environment, so that the peculiar smell is effectively eliminated, and the nitrogen element in the gas is fully utilized to promote the growth of plants. The algal-bacterial symbiotic targeted nitrogen and sulfur removal biological treatment system constructed by the utility model can effectively remove pollutants, and meanwhile, through strain screening and filler modification, the efficiency and stability of the biological treatment system can be further improved, and a support is provided for foul smell treatment of a sewage treatment plant.
