The invention provides a hair-protection unhairing and liming waste liquor recycling method in the tanning industry. In the method, an organic sulfur unhairing material is used to carry out hair-protection unhairing; sodium sulfide and lime are used to carry out liming processing; after solid impurities in liming waste liquor are removed, the liming waste liquor replaces water to be reused in the liming processing; after being circulated for 1 to 5 times, the liming waste liquor is processed by acid, so that sodium sulfide in the waste liquor is converted into hydrogen sulfide and proteins also generate precipitates; the generated sodium sulfide is adsorbed by using sodium hydroxide and is reused in the liming processing; after the proteins in the processed waste liquor are filtered, the processed waste liquor is reused for pre-soaking, so that the complete circulation of the liming waste liquor is realized.

The invention discloses a method for combining large-diameter tree / tree house with multiple small trees and provides a method for combining small tree seedlings with a ground diameter of phi (1cm-3cm) into one tree and growing into a tree with a huge diameter in 5-10 years. Moreover, another function of the tree is that the tree is a new variety not existing in the nature. The method for combining large-diameter tree / tree house with multiple small trees comprises the technical procedure as follows: small tree seedlings with a ground diameter of phi (around 1cm-3cm) and a height of 1.5-3m are selected; then a pit is dug and a plurality of small tree seedlings are together placed in the pit; then two planes of two rind parts of 60mm sections of the trunks of two small tree seedlings in the most center which can be contacted are selected and flatly jointed; then 2-4 small holes are drilled in two contact points; crabsticks with a ground diameter of phi (1mm) are inserted into the holes; then the residual crabsticks are removed so that the crabsticks are aligned to an outer wall; then the crabsticks are fixed by thin ropes; 502 or white latex glue is coated between the crabsticks and the hole walls so that the crabsticks and the hole walls are firmly stuck; after fixation, the rope is unfastened; and so forth, a neighboring tree is placed closely and connected by crabsticks; afterthe connection is completed, the trees are bound by a soft rope; then the soft rope is removed in a half year so that the trees can grow naturally; after the trees grow higher, the height positions are connected by adopting the same method. The trunks are outwards bent at a required height and are fixed by bending plates with a bending angle of 120-150 degrees (as shown in diagram 3); then the bending plates are removed in a half year; and the trees are conventionally and carefully cultured; the crown is pruned; and the trees grow into a tree with a huge diameter in a plurality of years.

The invention discloses a method for extracting lead from lead sulfide concentrate through two-stage countercurrent constant-pressure oxidizing leaching of a sulfonic acid solution. The method comprises the following steps of mixing the sulfonic acid solution with lead sulfide concentrate and a surfactant in a reaction kettle, adopting iron ions as an oxidation catalyst, and performing a two-stage countercurrent leaching method of neutral oxidizing leaching and acid oxidizing leaching under constant pressure to achieve selective leaching of lead; oxidizing sulfur in the concentrate into elemental sulfur which remains in slag; performing electrodeposition on a neutral leaching solution so as to obtain metal lead and a waste electrolyte; performing next acid leaching on the waste electrolyte or preparing an electrolyte from the waste electrolyte and a new solution; and enabling an acid leaching solution to enter the procedure of the next neutral leaching. Through the adoption of the method, not only can the efficient extraction of lead be realized, but also the cyclic utilization of the leaching solution and the electrolyte is realized, and waste solutions are not produced, so that green and environmental protection requirements are met.
