The harm of domestic sewage

With the rapid development of the sewage treatment market, China's sewage treatment output has also ended the long-term lingering situation and achieved rapid growth. The sewage treatment output of our country increased from 460,000 tons in 2000 to 2.36 million tons in 2004, with an average annual growth rate of 82.6%, the proportion of domestic market demand also increased from 24.47% in 2000 to 52.80% in 2004. During the same period, world wastewater treatment production grew at a rate of only about 6%.

Since the late 1990s, China's TiSCO, Baosteel and Baoxin, Zhangpu and other state-owned and joint venture enterprises have built a series of sewage treatment production lines through the introduction and technical transformation, sewage treatment technology and equipment have reached the international advanced level, and sewage treatment production has begun to take shape. The variety structure of sewage treatment has also undergone positive changes, and the quality of sewage treatment products has improved rapidly. In particular, the domestic wastewater treatment cold-rolled sheet has grown rapidly, in 2003, the domestic cold-rolled sheet production reached 1.7 million tons, exceeding the import volume for the first time, and the self-sufficiency rate reached 66%; In 2004, the domestic output of cold-rolled sheet reached 2 million tons, and the self-sufficiency rate reached more than 70%. From the end of 2004 to the end of 2005, the domestic cold rolled sewage treatment capacity will increase by about 1.5 million tons, basically meeting the domestic market demand. By 2007, China will become a net exporter of sewage treatment.

On the whole, China's sewage treatment is undergoing a profound transformation from small scale, low level, single variety, seriously unable to meet the needs to a considerable scale and level, significantly improve the quality of varieties and initially meet the requirements of national economic development, and the demand for sewage treatment will gradually achieve self-sufficiency.

Deal with the problem

Problem 1. As population increases, sewage increases

In our country, with the increase of urban population and the development of industrial and agricultural production, sewage discharge is also increasing day by day, water pollution is quite serious, and almost throughout the country. By the end of 2000, 310 of the country's 663 cities had built sewage treatment facilities and 427 sewage treatment plants, with an annual sewage treatment capacity of 11.36 billion cubic meters and a sewage treatment rate of only 34.23 percent.

The second problem is the urgent need for funds to accelerate development

Under the conditions of socialist market economy, sewage treatment begins with a certain amount of capital investment. The scale of sewage treatment funds determines the scale of sewage treatment. The development speed of sewage treatment funds determines the speed of sewage treatment development and the speed of sewage treatment technology progress. In the actual sewage treatment, the decision scheme with advanced technology and low treatment cost is usually the one with large amount of prepaid capital. In this sense, the faster the development of funds themselves, the faster the progress and application of sewage treatment technology, and the faster sewage treatment can be.

(Problem 3) Dealing with funds, the source is difficult

1, the difficulty of the source of capital for urban sewage treatment in China

For a long time, China's urban sewage treatment facilities adopt a policy of free use, not only the expansion of reproduction by financial investment, simple reproduction also needs financial appropriations to complete, financial appropriations have therefore become the source of investment in the maintenance and construction of sewage treatment facilities. Only in different periods, the name of the source is different, but it is a financial center of the capital cycle. The reform of the economic system has negated China's traditional "unified" financial model, denied the identity of the state as a producer and operator, and also denied the unity of the identity of the owner of the means of production and the exercise of political power, requiring the separation of government and enterprise, and the separation of government and capital. In conformity with this, on the premise of unified finance with the state as the main body, our country finance divides into public finance and state-owned assets management. Public finance is a country that appears as a political power, raising funds mainly in the form of taxation to solve problems that cannot be solved by market allocation of resources and to meet public needs. Urban sewage treatment is a public welfare undertaking, and the financial allocation of sewage treatment funds should be the public financial expenditure. Because China's socialist market economic system reform is still deepening, the proportion of public financial revenue in GDP, the proportion of central public financial revenue in public financial revenue is not reasonable enough, urban sewage treatment funds are difficult to come from the vast majority of financial grants or loans like the United States and other developed countries.
