Water-saving and emission-reduction technology for producing sugar through enzymolysis of lignocellulose treated with alkali

The invention discloses a water-saving and emission-reduction technology for producing sugar through enzymolysis of lignocellulose treated with alkali. The water-saving and emission-reduction technology mainly comprises the processes of alkali treatment of lignocellulose, solid and liquid separation, and washing and enzymolysis saccharification of lignocellulose pretreatment residues. By means of the water-saving and emission-reduction technology, while efficient conversion of lignocellulose is ensured, the emission amount of waste liquid is reduced, the amount of washing water for pretreating lignocellulose is reduced, and the purposes of water saving and emission reduction are achieved. 本发明公开了种碱处理木质纤维素酶解产糖的节水减排工艺，其主要工序包括木质纤维素的碱处理、固液分离、木质纤维素预处理渣的洗涤和酶解糖化。本发明在保证木质纤维素高效转化的同时，减少废液排放量，降低了预处理木质纤维素的洗涤用水水量，达到了节水减排的目的。
