The defects are that the equipment is arranged more, the pipelines and the electric instruments are controlled more, the installation workload is large, the energy consumption is high and the investment is large.
(2) A pump multi-point medicine feeding mode is to circulate medicine by a big pump, the circulation pipe passes through all the medicine feeding points in turn, and branches at the medicine feeding points are added to the medicine feeding points. The advantages are that: the equipment is few, the pipelines are few, and the energy consumption is low; disadvantages: the flowmeter and the control valve are added to realize automatic control, and the valves are arranged in the outdoor environment in the field in a scattered manner, so that the service life is short due to corrosion of the acid-base wastewater and the medicament in the field.
(3) The medicine adding mode is that a high-level tank is arranged, the medicine is led out from the main pipe of the high-level tank, passes through the vicinity of all medicine adding points, and is separated to be connected into each medicine adding point. The advantages are that: the electric equipment is few, the pipelines are few, and the energy consumption is low; disadvantages: the dosage of the medicament is influenced by the liquid level of the elevated tank, the flow is unstable, the flow difference between the branch close to the elevated tank and the branch at the tail end is large, and the dosage is not well controlled. The medicine in the main pipe does not circulate and is easy to freeze in colder areas.
