The Analysis Of Development And Application On The Municipal Sewage Disoposal Equipment Production Domesticization

In order to better settle the urban water pollution control and protection of the water resource in the modernization process of our country, accelerate the construction of treatment facilities of municipal sewage, improve the technical equipment level of municipal sewage of our country, realize the production domesticization of the city sewage disposal equipment as soon as possible, offer the support of the technology and equipment for development of the municipal sewage factory of our country.This subject makes the objective appraisal of the real standard of the sewage disposal equipment of our country, which adopts the way of filling the investigation form. The representative sewage treatment plants and equipment factories in such aspects as equipment, scale, investment, operating and management were made the sample investigation.The appraisal adopts the method of the index grade estimation. After the census data is gathered and counted.The experts who give a mark from the economic index, the dependability index and the advanced index of the equipment make an overall objective appraisal.Through analyzing synthetically we know that: some equipments such as air blower and vertical aeration equipment installed over the water, are mainly produced by the state-run enterprises, whose technology is up to the advanced international standards closely, and whose overall level is also higher than the import equipment, the rate of utilization of the domestic equipments which are used widely and manufactured easily in the sewage treatment plant are relatively high. For the more difficult technology equipments whose manufactures are few, the country should offer the support of technology import and development, and encourage the enterprises to produce them.Through the technical and economic evaluation of the equipment , the equipment type choice table are put forward which accords with the main technology recommended by the national industry' technological policy. Through the application investigation of the domestic equipment in the demonstration project, the followings conclusion are made: It is feasible that the domestic equipments are used in the sewage treatment plants of small and medium-sized cities, and mostequipments are better, which offers the reference basis for that the government , decision department , equipment manufacturing enterprise , investor choose suitable technology and equipment.
