The reporter recently learned from the relevant departments of Hainan Province that during the “Eleventh Five-Year Plan†period, Hainan Province will build 22 sewage treatment plants to control the emission of chemical oxygen demand (COD) and complete the national emission reduction targets.
In 2006, Hainan's sulfur dioxide emissions were 23,800 tons and COD emissions were 99,000 tons. Both indicators exceeded the State Council's pollution emission reduction targets. Among them, sulfur dioxide is mainly industrial emissions, mainly because the pulp mill production has reached the design scale, and COD is mainly for domestic sewage discharge, mainly because the domestic sewage treatment rate is low. In addition to Haikou and Sanya, there are urban sewage treatment plants in the province. In addition to sewage treatment of urban sewage, other cities and counties have no sewage treatment facilities, and a large number of urban domestic sewage is directly discharged into rivers and lakes without treatment.
According to He Shaoqun, deputy director of the Department of Land and Resources of Hainan Province, Hainan must speed up the construction of domestic sewage treatment plants, ensure that more than 60% of domestic sewage treatment is up to standard, and reduce the living COD by 73,000 tons, thus ensuring industrial development. Complete the task of reducing emissions. During the “Eleventh Five-Year Plan†period, Hainan Province must implement the construction of 22 sewage treatment plants.
