Buildings with similar functions should be concentrated as much as possible to avoid mixed layout of buildings with different functions. The layout of old areas should be gradually transformed on the basis of full utilization.
3.2.1 Land for residential buildings

Sanitary protection distance refers to the minimum distance from the edge of the main pollution source of enterprises and places that produce harmful factors to the boundary of residential building land: 2 A dust protection belt should be set within the dust protection distance of serious pollution sources. Chicken farms, pig farms and meat processing plants should use dark ditches or pipeline drainage ditches, and should be equipped with impermeable manure storage tanks. It is best to use biogas or other appropriate methods nearby for harmless treatment.
For any enterprise (place) whose production scale is less than or exceeds the above-mentioned scale specified in this standard or has other special circumstances, its sanitary protection distance shall be determined by the local health supervision department with reference to this standard.
3.2.2 Industrial and agricultural sideline land should be arranged on the upwind side of the local minimum wind direction frequency in summer, and industrial and sideline industries with serious pollution should be arranged at the farthest end from residential land.
