Sludge deodorizing agent

Abstract

The invention relates to the sludge biochemical deodorizing technology, in particular to a sludge deodorizing agent which can be applied to rivers, lakes and ports. The sludge deodorizing agent is prepared from the following raw materials by mass percent: 0.5 to 1 percent of ginger juice, 2 to 4 percent of pyrola rotundifolia juice, 3 to 4 percent of cedar wood oil, 2.5 to 3 percent of laurus nobilis juice, 1 to 2 percent of ilex pur-purea juice, 2 to 3 percent of pine needle oil, 0.5 to 1 percent of sandalwood oil, 1 to 2 percent of mint juice, 0.5 to 1 percent of lemon oil, 0.5 to 1 percentof rose oil, 0.2 to 0.5 percent of fructus anisi stellati oil, 0.5 to 0.8 percent of Sichuan pepper oil, 5 to 10 percent of active agent, 2 to 3 percent of camphorwood oil, and 70 percent of purifiedwater. By adopting the sludge deodorizing agent, odor gases such as H2S, CH4, CH3SH, NH3 and VOC generated in the sludge treatment process can be rapidly eliminated, the removal rate can reach 95 percent or higher, rapidness and high efficiency can be realized, the secondary pollution is avoided, the deodorizing agent can be directly sprayed for deodorization and can also treat the odor gases after being collected, the investment is small, and the equipment maintenance is simple; and the operation is convenient, the operation parameters of a controller can be adjusted at any time according tothe concentration of the odor gases, and an optimum deodorizing effect can be achieved.

Description

technical field [0001] The invention relates to sludge biochemical deodorization technology, in particular to a sludge deodorizer applicable to rivers, lakes and ports. Background technique [0002] Due to the rapid development of cities, environmental protection measures are relatively lagging behind, and many rivers, lakes, and ports are seriously polluted, causing environmental problems such as deterioration of water quality, black bottom mud, ecological damage, and severe stench of water bodies. [0003] In recent years, local governments have strengthened the control of pollution sources, and the pollution load entering rivers, lakes, ports and other water bodies has been reduced year by year; The local environment poses a nuisance, especially when the bottom mud at low tide level is exposed to the water surface, the odor problem is more serious. [0004] Traditionally, dredging is often regarded as a method of deodorization, but in fact it is impossible to successfull...

AI Technical Summary

Problems solved by technology

Therefore, after the completion of the dredging project, although the thickness of the bottom mud has been reduced, its exposed area has not been reduced, so the reduction of the odor is limited and cannot be completely deodorized

At present, there is no report on deodorization technology, and it is of great practical significance to develop a technology that can deodorize sludge.
