Membrane　fouling　is　the　Achilles　heel　of　membrane-based　technologies.　Severe　membrane　fouling　occurs　when　a　single　microfiltration　(MF)　membrane　is　used　to　treat　shale　gas　produced　water　(SGPW).　Activated　by　Fe(II),　sodium　percarbonate　(SPC)　oxidation　combined　with　aluminum　sulfate　coagulation　was　used　in　this　study　to　evaluate　the　alleviation　of　MF　fouling　for　the　treatment　of　two　typical　SGPW　samples　with　different　water　quality　characteristics　from　Sichuan　Basin.　Results　showed　that　pre-treated　by　oxidation　and　coagulation,　more　than　88%　of　turbidity,　11%-23%　of　UV254,　and　11%-36%　of　DOC　were　removed.　With　the　increase　in　SPC　dosage,　there　was　a　decrease　in　fluorescent　organics,　primarily　reducing　soluble　microbial　by-product-like　components　by　up　to　37.0%　for　sample　1　and　aromatic　protein　and　soluble　microbial　by-product-like　components　by　up　to　66.7%　and　71.2%　for　sample　2,　respectively.　Compared　to　low　normalized　fluxes　(2%-6%)　for　the　raw　SGPW,　61%-79%　of　normalized　fluxes　were　obtained　using　the　combination　of　10　mmol/L　SPC　and　0.9　mmol/L　Al-2(SO4)(3)center　dot　18H(2)O.　There　was　a　general　evolution　of　complete　blocking　to　intermediate　blocking　or　cake　layer　filtration　for　membrane　fouling　mechanism.　Scanning　electron　microscopy　observation,　deposited　foulants　on　membrane　surface　and　Fourier　transform　infrared　analysis　further　confirmed　the　superior　performance　of　the　combination　of　SPC　oxidation　and　coagulation.　Correlation　analysis　showed　that　UV254　(R-2　=　0.79-0.95)　played　the　most　significant　role　in　membrane　fouling.　Overall,　this　combined　pretreatment　process　showed　a　great　potential　in　MF　membrane　fouling　control　during　the　treatment　of　SGPW.
