This invention discloses an integrated wastewater treatment device and method for enrichment and in-situ digestion. The method operates cyclically within a reactor, with each cycle comprising: an enrichment and adsorption stage, in which organic wastewater is introduced into the reactor; by controlling the influent and internal circulation, a hydraulic upflow velocity is created within the reactor, causing the anaerobic granular sludge bed to expand; this hydraulic condition induces the granular sludge to secrete extracellular polymers and utilizes the anaerobic granular sludge and its extracellular polymers to adsorb and enrich dissolved organic matter in the influent; and an in-situ digestion and regeneration stage, in which the influent is stopped, and under continuous internal circulation and anaerobic conditions, the inherent methanogenic bacteria within the granular sludge convert organic matter into methane in situ. This biodegradation process simultaneously regenerates the adsorption sites of the granular sludge, preparing for the next cycle.
