Simple and quick-result method of treating polluted rivers in towns

The invention discloses a simple and quick-result method of treating polluted rivers in towns. On one hand, the method comprises the following procedures, the weight of sludge is calculated after the water in the river is drained away. Quicklime or quicklime powder is well distributed in the river and the weight ratio of the quicklime or quicklime powder to the sluge is in the range of 1:90-1:110. Quicklime or quicklime powder will react with the sluge or water in the river to make the PH value of the sludge 10. On the other hand, the method also comprises the following procedures, the weight of water in the river is calculated according to the volume of the water. Quicklime or quicklime powder is well distributed in the river and the weight ratio of the quicklime or quicklime powder to the water is in the range of 1:900-1:1100. Quicklime or quicklime powder will react with the water to make the PH value of the water 10. The above method has the advantages of simple operation, low cost and obvious effect.
