The invention discloses a method for in-situ decentralized treatment of pig free-ranging manure liquid. The method comprises the following steps: enabling to-be-treated sewage to enter and fill a pretreatment unit from top to bottom through a water inlet pipe, settling a part of sludge in a sludge box at the bottom, and enabling the water body subjected to flocculation settling to enter the bottom of a phosphorus removal main reaction unit through a water pipeline and stably flow from bottom to top; enable the water to fully contact and react with a micro-electrochemical functional ceramsite material so as to adsorb and degrade soluble phosphorus harmful substances in the sewage; and similarly, transferring the water body to an advanced treatment unit from a dephosphorization main reaction unit from bottom to top, conducting advanced treatment by adopting a membrane technology and a strong electrochemical technology, and letting the purified reclaimed water automatically flow out of a water outlet in the uppe
