Abstract
The invention relates to the field of sludge treatment, in particular to a sludge treatment method. Aiming at the problems in the prior art, the invention provides a sludge treatment method with good flocculation effect and low treatment cost. The sludge treatment method comprises the following steps of: 1) decomposing, conveying the sludge into a sludge mixing tank, and putting an inorganic polymer water purifying agent into the sludge mixing tank; 2) conveying the sludge treated by the inorganic polymer water purifying agent into a stirring and mixing bucket, adding a cationic flocculant, and stirring for full reaction; and 3) conveying the reacted sludge into a filter press and dewatering. The sludge treated by the process has low water content, and the flocculation effect is good; and then the sludge is treated, so the treatment cost is low.
Description
Technical field
The present invention relates to field of sludge treatment, be specifically related to a kind of method for sludge treatment.
Background technology
Pulping and paper-making is one of important industry of Chinese national economy, and the output of the carton cardboard of China's production at present leaps to the first in the world, and over nearly 3 years, secondary stock proportion in paper making raw material surpasses 56%.But, in paper-making process, produced a large amount of waste sludge from paper mill mud, with the present papermaking scale of China, estimate that the paper mill sludge that produces has reached 2,000 ten thousand tons/year.The improvement of paper mill sludge becomes the main environment protection treating object of China's paper industry.
Paper mill sludge is mainly derived from following three aspects: the one, and chemical pulping alkali reclaims station white clay recycle section, is the product of lotusization reaction, belongs to precipitated chalk; The 2nd, the biological sludge that produces in the paper waste treating processes; Three stones come from the deinked sludge of paper-making process from waste paper deinking workshop section, the non-fiber impurity of screening scavenging process.At present, back two kinds of main sources that mud is China's papermaking weapon.
The prime cost of biological sludge is generally: fiber fines, xylogen and derivative thereof and some organism.The complex chemical composition of waste paper pulp-making waste residue, organism accounts for 70% ~ 90%, inorganics and metallic impurity account for 10% ~ 30%, mainly containing plastics class, fiber fines, rag, cotton yarn, mess-tin, abandoned optical discs in the organism and from the various organic-fuels of printing-ink, tackiness agent etc., mainly is other inorganic salt that add in papermaking filler (as alumina etc.), coating (as kaolin etc.) and the pulping and papermaking processes in the inorganics.The chemical constitution and the characteristic of the solid slag that waste paper pulp-making and deinking process produce also are subjected to many factor affecting.
These biochemistry and materialized mud just carry out conventional processed in treating processes at present, and the dewatering of mud is poor, the water ratio height, the processing cost height.The problem that prior art exists is: have in the conventional sludge dewatering that flocculating effect is poor, water ratio height and a processing cost height.
Summary of the invention
Problem at prior art exists the invention provides the method for sludge treatment that a kind of flocculating effect is good, processing cost is low.
A kind of method for sludge treatment may further comprise the steps:
1) decomposes, mud is transported in the mud mixing pit, in the mud mixing pit, drop into inorganic high molecular water purifier;
2) mud that inorganic high molecular water purifier was handled is sent into and is mixed bucket, adds cationic flocculant simultaneously, stirs, and it is fully reacted;
3) reacted mud is sent into pressure filter, dehydration.
Wherein, described mud is biochemical sludge and materialized mud.
Wherein, among the described step b, the mud that inorganic high molecular water purifier was handled is pumped into through pipeline by sludge pump and mixes in the bucket, adds cationic flocculant in pipeline.
Wherein, inorganic high molecular water purifier be polymerize aluminum chloride, aluminium iron polychloride, aluminium chlorohydroxide, ferrous sulfate, Tai-Ace S 150, bodied ferric sulfate wherein any one.
Wherein, described cationic flocculant be polyacrylamide, polyacrylic acid, sodium polyacrylate, calcium polyacrylate (CPA) wherein any one.
Compared with prior art, advantage of the present invention is as follows:
A kind of method for sludge treatment may further comprise the steps: 1) decompose, mud is transported in the mud mixing pit, drop into inorganic high molecular water purifier in the mud mixing pit; 2) mud that inorganic high molecular water purifier was handled is sent into the bucket that mixes before the water extracter, adds the organic polymer cationic polyacrylamide simultaneously, stirs, and it is fully reacted; 3) mud after the flocculation reaction is sent into pressure filter, dehydration.The sludge moisture content of crossing through art breading of the present invention is very low, and flocculating effect is good, carries out sludge treatment afterwards again, and processing cost is low.
