我添加了两行和一些额外的代码
\documentclass[twoside]{memoir}
\makeatletter
\renewcommand{\@twocolfootfmt}[1]{%
\@preamtwofmt
{%
\hspace*{-\footparindent}% <-- added
\footfootmark%
\strut {\foottextfont #1}\strut\par}\allowbreak}
\renewcommand{\@preamtwofmt}{%
\hsize .45\hsize
\parindent=\z@
\tolerance=5000\relax
\raggedright
\parindent=\footparindent% <-- added
\leavevmode}
\makeatother
\setlength\footmarkwidth{1em}
\setlength\footparindent{1.5em}
\footmarkstyle{\hbox to \footmarkwidth{\textsuperscript{#1}\hfil}}
\twocolumnfootnotes
\usepackage{lipsum}
\begin{document}
text\footnote{\lipsum[1-2]}\footnote{\lipsum[3-5]} text text
\end{document}
