design principles

(1) Adopt high-efficiency, energy-saving, advanced and reliable sewage treatment processes, try to use sewage treatment systems with simple management, low energy consumption and efficiency, and reduce infrastructure investment and daily operating costs;

(2) When formulating the plan, it should be technically reliable and economically reasonable. Combined with the specific characteristics of sewage and the successful experience of relevant sewage treatment at home and abroad, new technologies should be adopted as much as possible on the premise of ensuring reliable functions and convenient operation and management to improve sewage treatment. Effect, reduce sewage treatment costs;

(3) Adopt equipment with a high degree of automation to achieve reliable technology and reasonable economy, realize automation, proceduralization and simplification of operation and management, and try to achieve unmanned management, thereby effectively reducing the operating costs of sewage treatment;

(4) Properly handle and dispose of grid slag, sludge, etc. generated during wastewater treatment to avoid secondary pollution;

(5) The structures and equipment of the wastewater treatment station should be reasonably arranged, compact in structure, and save land occupation;

(6) Design strictly in accordance with the conditions defined by the construction party and adapt to the actual situation and requirements of the project.
