The invention discloses a water-based drilling soft solid waste recycling treatment and utilization technology. The water-based drilling soft solid waste recycling treatment and utilization technologycomprises the steps that drilling soft solid waste is mixed evenly, a microorganism strain with a decomposing effect is inoculated at the proportion of 0.5%-1% by weight, and even mixing is carried out; then, a microorganism nutrient of 0.5%-2% of the solid waste by weight is added and mixed evenly, and the mixture is evenly mixed with soil with the water content of 15%-20%, wherein the mixing proportion of the solid waste and the soil is 1:(0.5-3) by weight; and the treated mixture is stacked, plants are planted or grass seeds are cast in the mixture, and a microorganism-soil-plant united system is used for decomposing treatment of organic pollutants in the drilling soft solid waste. By means of the water-based drilling soft solid waste recycling treatment and utilization technology, COD, Oil and other substances in the drilling work soft solid waste can be effectively decomposed and removed, part of the organic pollutants are decomposed into simple inorganic substances, and part ofthe organic pollutants are decomposed into humus, so that pollutants in the solid waste are removed, and the purposes of harmlessness and recycling utilization of the solid waste are achieved.
