description The invention relates to a remediation technology in the field of soil pollution treatment, and particularly discloses an in-situ remediation system for contaminated soil and a method for remediatingammonia nitrogen contaminated soil by using the remediation system. The remediation system for the contaminated soil comprises a ventilation shaft, an extraction well, a gas extraction device, a gas-liquid separation device, a gas treatment device and a waste liquid collection device, wherein the gas treatment device is an acid washing tower. According to the invention, ammonia nitrogen gas is extracted from the ammonia nitrogen contaminated soil through the gas extraction device in the remediation system, and is then separated from water by using the gas-liquid separation device; the separated ammonia nitrogen gas is subjected to acid pickling via the gas treatment device; and waste liquid is collected through the waste liquid collection device. The soil remediation system and method provided by the invention are
