The invention relates to a paper pulp production technique which combines biolysis with machine work and has no used water discharging. It includes smashing the raw material, laying crack, biolysis, high-pressure pressing bursting, mediating, jordaning, pulp screening, and shoving. The used water can be used circularly to realize zero discharging. The paper pulp raw material includes straw, ditch reed, bamboo etc. The production technique has the advantages of no pollution, saving water, and low material consumption etc. And its cost is 40% of the chemical process. It is green high and new-technology industries with high economic benefit used to make food wrap paper, medicine wrap paper, and various papers.
