The invention discloses a method for repairing a waste pit into a paddy field based on construction muck filling engineering. The method comprises the following steps of S1, extending a hard pipe intothe pit bottom of the pit, and continuously blowing air into the pit through the pipe; S2, pouring construction muck into the pit while blowing air into the pit through the pipe, and stopping pouringthe construction muck when the water content of sludge in the pit is reduced to 60 percent; S3, further blowing air into the sludge until the water content of the sludge is reduced to 30 percent, andstopping blowing air; S4, pouring crushed straw, fruit and vegetable residues and livestock and poultry manure into the sludge, and fermenting for 240 to 280 hours while maintaining the temperature of the crushed straw, the fruit and vegetable residues and the livestock and poultry manure to be 25 to 40 DEG C; S5, overturning soil above fermented residues.
本申请公开了基于建筑渣土充填工程将废弃矿坑修复成水稻田的方法，包括如下步骤：S1:将硬质管子伸入矿坑的坑底处，并通过所述管子不断地向矿坑内鼓气；S2:在通过管子一边向矿坑内鼓气的同时，一边向矿坑内倾倒建筑渣土，当矿坑中的污泥的含水率降至60％时停止倾倒建筑渣土；S3：进一步向污泥中鼓气直至污泥的含水率降至30％后停止鼓气；S4：向污泥中倒入秸秆碎沫、果蔬残渣及畜禽粪便，并使维持三者温度为25℃～40℃下发酵240h～280h；S5：将泥土倾覆在发酵渣的上方。
