The invention discloses an environment-friendly domestic wastewater treatment method. According to the environment-friendly domestic wastewater treatment method, a box body is included; an adsorptionbox is fixedly connected between the right side of the top of an inner wall of the box body and the top of the right side of the inner wall; a top box is fixedly connected with the left side of the top of the box body; bottom boxes are fixedly connected between the front and rear sides of the inner wall of the box body; the two bottom boxes are arranged; opposite sides of the two bottom boxes arefixedly connected; a vertical plate penetrates through the bottom of the top box; the bottom of the vertical plate penetrates through the box body and extends into the box body; the bottom of the inner wall of the vertical plate is fixedly connected with an extrusion spring. The environment-friendly domestic wastewater treatment method relates to the technical field of environment-friendly domestic wastewater treatment devices. The environment-friendly domestic wastewater treatment device is used for effectively collecting and treating wastewater and can be used for precipitating relatively small heavy matters, such as substances including sand stones, in the wastewater; two storage parts are arranged so that filtering is not influenced in a precipitation process; normal proceeding of thedevice is ensured and unnecessary wastes are reduced.
