I tried this command:

/c local surface = game.player.surface; for coord in surface.get_chunks() do surface.pollute({coord.x * 32, coord.y * 32}, -10000000) end

But when I open map and click on red button, pollution cloud still shows.
F4 - pollution chunks, all my base is still polluted.

I just can't remove pollution.... .

If your base is still running, it still produces pollution, and the environment removes it. The settings are available in 0.15 difficulty settings when starting a new game. To deal with pollution "the hard way", there are polllution cleaning modules in Bob's Modules you can use to reduce pollution production in your machines, and there are mods with pollution cleaning machines.
