Integrated system for recovering waste heat and residual heat of sludge and sewage treatment plant

An integrated system for recovering waste heat and residual heat of a sludge and sewage treatment plant comprises a sludge/sewage treatment process cooling system terminal heat collecting device, wherein the sludge/sewage treatment process cooling system terminal heat collecting device is connected with a waste/residual heat recovery device through a pump and a valve, the waste/residual heat recovery device is connected with a heat distribution system through a pump, a valve and a pipe, and the heat distribution system is connected with a heat using system through a valve and a pipe. When the integrated system runs, heat of high-temperature water produced by a treatment terminal of the sludge/sewage treatment plant or the process residual heat can be collected, and heat radiated by a residual heat recovery system motor meets the heat system demands, such as heat preservation of an anaerobic tank body and heating and bath in winter. The integrated system fully utilizes the waste heat, saves a large amount of e
