Brief summary: The is a prospective, open-label, dose-climbing clinical study assessing the efficacy and safety of CD30 CAR-T in the treatment of r/r CD30+ lymphoma. Plan to recruit 15 subjects with r/r CD30+ lymphoma。

Detailed description: The goal of this clinical trial is to explore the effect of CD30 CAR-T on CD30 positive relapsed/refractory lymphoma. The main questions it aims to answer are:

To evaluate the safety of autologous CD30 CAR-T therapy in CD30-positive relapsed/refractory lymphoma; To evaluate the efficacy of autologous CD30 CAR-T therapy for CD30-positive relapsed/refractory lymphoma; To evaluate the metabolism of CD30 CAR-T cells in vivo; Preliminary evaluation of the correlation between CAR T cell dose and clinical efficacy.

Eligibility criteria: Inclusion Criteria:

* Suffered from other malignant tumors, except for for skin basal cell carcinoma, skin squamous cell carcinoma and cervical carcinoma in situ undergoing the radical treatment;
* Received Anti-CD30 Ab therapy within 4 weeks before enrollment;
* Unresolved \> Grade 1 non-hematologic toxicity associated with any prior treatments;
* Active uncontrolled bleeding or a known bleeding diathesis;
* Autologous hematopoietic stem cell transplantation was performed within 6 weeks;
* Uncontrollable active bacterial or fungal infection；
* Known allergy to the study drug and its components;
