1、summarization

Foul gas is a kind of substance which exists in sewage and solid castoffs and gives out stink, it is formed by emitting into the air during the process of flowing,fermenting,transporting and disposing.The main content in the foul gas is such malodorous volatiles asammonia, sulfureted hydrogen,mercaptan and thio ether. At present, there are various kinds of deodorization techniques and according to their mechanism of action, they can be devided into such methods as biological, chemical, physical,bio-chemical and physic-chemical, among them, biological deodorization is the most broadly applied for its safety,economic and effectiveness. While among the various biological deodorization techniques, soil deodorization is researched at the first and applied broadly.

2、Operating principal

Soil method is a kind of biological filtering technique to use colliod particles in soil as the filler, by using its absorption performance and decomposition function of such microbes in soil as bacteria and mildew to get rid of the pollutants.This method has capabilities of water supply and water keeping and relatively stable biocoenosis system with such characteristics and advantages as excessive strain types, complicated strain groups, easy to get film formation, simple equipment design and convenient management.But it conqurs a large area, and the open style field reduces the ventilation because of the climate reason, and the bad biological activity reduces the treatment effect and increse the cost for operation and maintenance.

3、Technique perfomance

In respect to some features of biological soil method and combined with some international experiences of soil deodorization and deodorization experiences we accumulated through these years, our company researched and developped improved soil deodorization technique.

The improved soil deodorization keeps such advantages of old soil method as simple equipment design and convenient management as well as such characteristics of soil method as excessive strain types, complicated strain groups, easy to get film formation. At the same time, it avoids such abuses of the soil in the open field as low ventilation, easy to get hardened and flow cutted and short circuit. High deodorization effectiveness, small area occupancy, can accommodate different inlet concentration fastigium, low operation cost and convenient management is the characteristics of the improved soil deodorization method. It concretely shows in several respects as follows:

①Unique inner construction, strong impact-resistance and organic load for treatment is also enforced.

②The metabolites of the microbes in improved soil method can be deleted through pre-treatment circulation liquid, prevent it from blocking and always keeps high deodorization effiency.

③It has relatively high treatment effiency for such acid pollutants as compounds with sulfur, compounds with nitrigon and compounds with halogenating.

④After by applying soil methods, to adjust PH becomes easier. The new inert filler is larger than the surface in area and requires no replacement under normal usage. The deododrization effiency is increased and usage life is prolonged, generally it can last 20 years.

In the improved soil deodorization systems provided by our company, we thoroughly employ the patent technology of our company.
