2. Construction wastewater treatment: industrial wastewater can be treated first and then discharged to reduce the pollution to rivers. Drains and grit chambers should be built on the construction site. Before construction, formulate construction measures to realize organized drainage, and take control measures to ensure drainage standards.

If the waste residue contains harmful components such as lead, chromium, arsenic, mercury, cyanide, sulfur, copper and pathogens, it should be reported to the local environmental protection department for approval and disposed of under the guidance of environmental protection personnel and supervision engineers.
4. Prevention and control of air pollution: improve the emission standard of industrial waste gas, strengthen the maintenance of mechanical vehicles during use, prevent the leakage of gasoline, diesel oil and engine oil, and ensure the smooth air intake and exhaust system.
5. Soil and water conservation measures: Take measures to control the spoil ground, pile up and use the spoil in an orderly manner according to the spoil plan approved by the supervision engineer, so as to prevent random dumping of spoil from blocking rivers, ditches and other waterways and reduce the flood discharge capacity of waterways.
