5 Planning of wastewater land treatment system
In order to implement environmental protection and sustainable development requirements
.
The designer should select a feasible and economically reasonable solution for the process technology, and make careful planning before it is determined.
In order to ensure that effective and unnecessary waste of funds or serious environmental damage is dealt with, extensive investigations and scientific demonstrations are required.

At this stage, data are collected and feasibility studies are conducted.
At the same time, a technical and economic evaluation of the wastewater land treatment system is carried out to achieve the goal of "social, economic and environmental benefits"
.
The main content and steps are: raw water quality, process plan, environmental impact, plant selection, land bearing capacity and discharge standards, design and calculation of land area, operating parameters, investment costs, prevention measures and pretreatment requirements for wastewater land treatment systems

2 The second phase of planning
Under the premise of the first stage of planning, the second stage of in-depth investigation and research will be carried out.
On the basis of the preliminary design, the plans and benefits will be compared, the best process flow will be determined, and the final design and calculation will be carried out
.
The main contents are: on-site for further research and investigation, selection criteria and preliminary design basis, project technical and economic evaluation and analysis, protection measures for land treatment system, operation and management
