The invention relates to a carbon source preparation method based on solid waste treatment, which comprises the following steps: S1, carrying out water washing dealkalization pretreatment on a red mud raw material through a water washing tank, and carrying out solid-liquid separation to obtain a water washing solution and primary dealkalized red mud; s2, preparing an organic acid fermentation broth; s3, carrying out drying treatment on the red mud subjected to primary dealkalization; s4, mixing the dried and dehydrated primary dealkalized red mud with the organic acid fermentation broth to obtain a mixed feed liquid, dissolving out the mixed feed liquid, and carrying out solid-liquid separation to obtain a dissolved liquid and final dealkalized red mud; and S5, adding a heavy metal ion regulator into the separated dissolution liquid, and mixing to obtain the carbon source for sewage treatment. The method has the effect of improving the utilization rate of the red mud in sewage treatment. 本申请涉及一种基于固废处理的碳源制备方法，
