Drip irrigation technique is more demanding for the clean level of irrigation water.Irrigation water main source have rivers, lake, reservoir,
Underground water.Since the source of irrigation water is more various, different source water quality is different.The prior art is only manually sentenced by experience
Disconnected filtering and backwashing time.By taking Huanghe water as an example, different times, different section, the water quality of different time are all had any different.If
Filtering and backwashing time are only artificially judged by experience, then will result in many problems.If filtration time is too long,
The impurity of so filter aggregation is just very more, and the pressure generated to filter also will increase, and causes the reduction of filter life.
Meanwhile the impurity not filtered can also increase, and pipe network is caused to block.If filtration time is too short, filter is from sewage draining exit
The water of outflow will increase, and cause the waste of irrigation water.The present invention determines the filtering of irrigation water using the turbidity of irrigation water as standard
Time and backwashing time, thus accurate controlling filter.Be conducive to the service life for improving filter, the stabilization for improving filtering water
Property, so that filter process is more scientific and standardizes.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and wants according to right of the present invention
Made equivalent variations is sought, is still belonged to the scope covered by the invention.
