The invention discloses integrated treatment equipment for domestic sewage of a power station. The integrated treatment equipment structurally comprises a mounting base, a water inlet pipe, a device shell body, fixed angle iron, a medicament mixing device, a squint window, a thread hole rack and a water outlet pipe, wherein the water inlet pipe is vertically embedded into the lower end of the left-side surface of the device shell body and is communicated with the lower end; the mounting base is parallelly mounted on the lower surface of the device shell body and is fixedly connected to form anintegrated structure through a welding manner; the fixed angle iron is mounted at the upper end of the front surface of the device shell body in parallel two by two and is mechanically connected; thethread hole rack is embedded into the front surface of the fixed angle iron to form the integrated structure with the fixed angle iron; the medicament mixing device is vertically connected with the left end of the upper surface of the device shell body and is communicated with the left end, so that a medicament can be quantitatively stirred at fixed time and then is quantitatively output when a sewage treatment device is used for carrying out domestic sewage treatment; the medicament in the equipment can be sufficiently mixed and stirred with water flow, so that the device can be more intelligent.
