Chimney-free sludge incineration method

Abstract

The invention discloses a chimney-free sludge incineration method. The method comprises the steps that 1, independent incineration is performed on sewage plant sludge, and incinerated smoke is purified; 2, an induced draft fan is adopted for pressurizing the purified smoke, the smoke is conveyed to a sewage plant sewage treatment end biological reaction tank through a pipeline; 3, air distributionpipes are evenly arranged along the bottom of the tank body of the biological reaction tank, and the smoke is introduced into the reaction tank through the air distribution pipes; 4, tail gas collection deodorization treatment is performed on the smoke introduced into the biological reaction tank. The method has multiple advantages, is high in innovation, and has the quite high project application value. On one hand, sewage is used for purifying the sludge incineration smoke, no chimney needs to be adopted for sludge incineration, smoke zero-discharge is achieved, and the sludge incinerationproject environment effect is greatly improved; on the other hand, heat energy generated by sludge organic matter incineration can be used for heating sewage, and sewage biological treatment is promoted. Due to synergic treatment of sewage and sludge odor, the low-carbon, energy-saving and environment-friendly sustainable sewage treatment idea is achieved truly.

Description

technical field [0001] The patent of the invention relates to the technical field of sewage and sludge treatment and environmental protection, specifically a method for incinerating sludge without a chimney. Background technique [0002] With the continuous improvement of the effluent quality requirements of sewage plants, the amount of sludge produced is also increasing. The treatment and disposal of sludge is an urgent task facing China's sewage treatment field. Among the many sludge treatment processes, incineration technology shows unique advantages, which can destroy all organic matter, kill all pathogens, and minimize sludge volume. At the same time, sludge incineration itself is a way to directly use the organic calorific value of sludge, and use its own calorific value to treat itself, which embodies the concept of energy recycling and sustainable development. In view of the advantages of reduction and harmlessness of sludge incineration, it should be the mainstream...

AI Technical Summary

Problems solved by technology

At present, many sewage treatment plants adopting the activated sludge method lower the water temperature in winter, especially in the cold northern regions, where the ambient temperature is tens of degrees below zero in winter, and the removal rate of various pollutants will be greatly reduced, making it difficult for the effluent quality to meet the standard in winter
