III.Renovate the water environment comprehensively to achieve the cleaner water in 21st century(1)

1.Prevent water pollution.

2.Reduce the municipal and industrial wastewater discharge in great amount.

3.Reduce the urban and agricultural runoff, limit the utilization of pesticide and fertilizer.

4. Strengthen the decision-making consciousness for ecology protection.

III.Renovate the water environment comprehensively to achieve the cleaner water in 21st century(2)

5. Stress water saving, which is the most effective measure for water pollution prevention.

6. Promote the water environment protection investment by market adjustment.

7. Take measures to advance the wastewater reuse.

Huaihe River Basin

Huaihe river water system:covers 189 thousand square kilometers, which account for 70 percent of the Huaihe River basin. The main-streem is 1000 kilometers long.

I. Water Pollution Situation

CODmn index of 130 sections exceeded the class water quality standard;

NH3-N index of 128 sections exceeded the class standard;

DO index of 85 sections exceeded the required standard;

BOD index of 39 sections exceeded the required standard;

Volatile phenol index of 27 sections exceeded the required standard.

1. Setup the basin negotiation and administration monitoring system of Chinese Characteristic

2. Issued the Interim Regulations for the Water Pollution Prevention and Control of Huaihe River Basin

3. Compiled the water pollution prevention and control plan

II. Water Pollution Preventionand Control Work

4. Strengthen the Industrial Structure Regulation

5. Discharge accord to the standard

6. Accelerate the municipal sewage treatment plant construction

7. Total amount control

II. Water Pollution Preventionand Control Work

III. Existing Problems

1.Some of the second third class tributaries could not meet the target of IV class water quality standard.

2.No thorough investigation was carried out for wastewater reuse (irrigation).

3.The construction of municipal wastewater treatment plant proceeded rather slowly.

4.The hurried constructed treatment projects brought forward series problems.

III. Existing Problems

5.Lacked cost effective and high efficiency technique for the treatment of the high concentration organic wastewater, which is difficult for biological degradation.

6.The supervision and administration measures were lagged behind.

7.The problems existing in the COD and NH3-N based organic pollutant water environment standard and administration system were discovered.

IV. The main tasks in the Tenth-Five-Year Plan

1.Strengthen the supervision and administration further and consolidate the discharge treatment achievements.

2.Accelerate the construction of the municipal wastewater treatment plant.

IV. The main tasks in the Tenth-Five-Year Plan

3.Compile the regional total amount control plan on the basis of total amount control plan of the whole basin, then carry it out through the implementation of the marketable discharge permits system.

4.Expand the financing channels, accelerate the speed of industrialization and marketization.
