With the acceleration of the process of urbanization and urban water pollution problem is getting worse, sewage treatment has become a very important issue. In the day-to-day work of sewage treatment, sewage treatment often caused by failure of the process of water quality indicators of the quality of the impact of increased operating costs of sewage treatment as well as some security issues. Therefore, the establishment of sewage treatment process of fault diagnosis has become an inevitable need for the community.

In recent years, the new sewage treatment plant there are a number of issues, sewage treatment experienced operatives as a result of inadequate sewage treatment is often caused by some fault in the process, resulting in lower operating efficiency, capacity utilization is also affected, and sewage treatment costs are substantially increased. The reason is that the accumulation of these experiences requires a longer period of time of practical experience and extensive knowledge, so only a small number of experts to master. Thus it is necessary to guide the introduction of a municipal wastewater treatment plant is running day-to-day decision-making support systems, expert system for operatives to carry out the guidance of experienced experts. Therefore the development of fault diagnosis expert system for sewage treatment system has a very important role.

Day-to-day city of urban sewage treatment process is very complex, can be divided into pre-treatment, primary treatment process, secondary treatment technology, advanced treatment processes and sludge treatment processes, and ultimately dispose of the sludge. And it has a high level of non-linear, non-steady-state characteristics and time-varying characteristics, the lack of effective measurement tools, or the lack of testing equipment, the delay and hysteresis characteristics. In this paper, against the backdrop of the sewage treatment process, the main points to look at the contents:

(1) the process of sewage treatment process of knowledge acquisition, the acquisition of knowledge, including the sewage treatment process failure phenomenon, failure causes and solutions.

(2) the process of sewage treatment process knowledge that the system of knowledge representation using production rule representation.

(3) of the sewage treatment process fault diagnosis expert system reasoning, is based mainly on the reasoning of uncertainty CLIPS.

(4) sewage fault diagnosis expert system development, mainly the use of expert system tool CLIPS.

In this paper, the background of Windows XP platform, the development of a wastewater treatment expert system for fault diagnosis expert system module development. The expert system uses a modular design approach, the realization of the knowledge base and inference engine of the separation. Through simulation tests show that the system has a high diagnostic performance.

Is getting more and more serious along with urbanized advancement's quickening with the urban water pollution question, the sewage treatment had already become a very important question. But in the daily sewage treatment work, will present the sewage treatment process breakdown to create frequently to the water leakage water quality target quality influence, the sewage treatment operating cost enlarges as well as some secure aspect question. Therefore, established the sewage treatment process failure diagnosis also to become society's necessity to need. in recent years, in the emerging Sewage treatment plant has some problems, the sewage treatment operator, because experiences the insufficiency, will create in the sewage treatment process frequently some breakdowns, will cause the operating efficiency to be low, the utilization of capacity has also come under the influence, but the sewage treatment cost actually largely will enhance. Its reason is these experience's accumulation request has the long time actual operation experience and the widespread knowledge, therefore only then the minority expert grasps. Therefore has the necessity to promote a set to use in instructing the Urban sewage treatment plant daily movement the decision support system, carries on the instruction which to the operator the expert system expert experiences. Therefore the development expert system failure diagnosis system has the very vital role to the sewage treatment. the daily city urban sewage processing craft is very complex, may divide into the pretreatment craft, the first-level processing craft, the second-level processing craft, the advanced treatment craft and the sludge treatment craft, as well as final sludge handling. Moreover it is having highly the misalignment, the unsteady state characteristic and the time-variable characteristic, lacks the effective measuring means or check-out facility's insufficiency, retards and characteristics greatly and so on hysteresis characteristics. This article take the sewage treatment craft as a background, mainly studies next several contents:
(1) the sewage treatment process craft's knowledge gain, its gain's knowledge mainly includes the sewage treatment process the breakdown phenomenon, the breakdown reason and the solution strategy.
(2) the sewage treatment process craft's knowledge indicated that this system's knowledge expressed the method uses the production pattern regular method of portrayal.
(3) the sewage treatment process failure diagnosis expert system inference, is mainly based on the CLIPS indefinite inference.
4) the sewage failure diagnosis expert system's development, mainly uses expert system development kit CLIPS.
this article in Windows the XP platform is a background, has developed the sewage treatment failure diagnosis expert system's expert system module development. This expert system uses modular the design method, has realized the knowledge library and the inducing equipment separation. Indicated through the simulation test that the system has the high diagnosis performance.
