The sewage treatment rate in Heilongjiang Province is only 56.72%.

Abstract: The reporter learned from related departments that as of September, Heilongjiang Province had built a total of 64 sewage treatment plants with a treatment capacity of 3.389 million cubic meters per day. The normal operation of the sewage treatment plant 46, pass the water trial run 17, one is being stopped production transformation. The sewage treatment plant has accumulated a total of 469 million cubic meters of sewage, reduced the COD by more than 200,000 tons, and the sewage treatment rate was 56.72%.

The history of urban sewage treatment industry in Heilongjiang Province is relatively serious. In 2009, it began to increase investment. As of the end of September this year, Heilongjiang Province invested 103.23 billion yuan in the construction of sewage treatment projects, started 129 projects, 67 completed projects, and included 40 municipal wastewater treatment projects in the Songhua River Basin Water Pollution Control Plan. The construction projects for the recycling and recycling facilities have been completed and put into operation. This is the period when the maximum investment amount, the largest number of construction projects, and the largest increase in carrying capacity have been achieved.

Despite this, there are still many problems in the urban sewage treatment work in Heilongjiang Province. From a construction point of view, regional development is unbalanced. Up till now, there are still 7 city-set cities and 41 county-level sewage treatment plants that have not been built and put into operation in the province. Most of the townships do not have any sewage treatment facilities; the implementation mechanism of the project is not perfect. The feasibility study of some projects is not sufficient, and the technical decision-making is administrative. The construction of sewage treatment projects has not been organized in accordance with the principles of enterprise construction and government network construction; the construction speed of wastewater treatment plants is fast, but the planned pipeline network indicators and actual completion targets have not been established. There is a gap, the construction of ancillary pipeline networks lags behind, and the rain and sewage diversion system is imperfect, directly affecting the collection and treatment capacity of sewage. From the aspect of operation, the operating load rate of the facilities is low. At present, there are 16 sewage treatment plants completed and put into operation in the province that do not meet the basic requirements of the state that the “load rate is not less than 60%”; the COD concentration in the wastewater treatment plant is not Stability, low efficiency of emission reduction, serious damage to the living environment of microbial flora, affecting the normal operation of the sewage treatment plant; incomplete water quality detection, not only the lack of effective supervision of the water quality of the sewage treatment plant, and some counties failed to strictly comply with the national Standard test items and frequency required for laboratory analysis.

Experts suggest that while the urban sewage treatment work in Heilongjiang Province continues to accelerate the construction of sewage treatment projects, it must speed up the improvement of supporting pipe network construction. Through a series of measures such as strengthening supervision, improving operational efficiency, strengthening system construction, and perfecting the drainage permit system, the urban sewage treatment project will be fully implemented.
