The invention discloses an acid etching solution recycling regeneration method. The acid etching solution recycling regeneration method comprises following steps that (1) an acid etching solution recycling regeneration system is prefabricated; (2) an etching waste solution produced by an etching production line is stored in a waste solution barrel, and the etching waste solution in the waste solution barrel is added into an ionic membrane electrolysis circulation device in an automatic detection adding mode; (3) a regenerated solution and elemental copper are produced in the mode that the etching waste solution is electrolyzed by the ionic membrane electrolysis circulating device, the regenerated solution is stored in a regenerated solution barrel, and the elemental copper is removed out in the form of a copper plate; and (4) an oxidant, hydrochloric acid and the regenerated solution stored in the regenerated solution barrel are correspondingly added into a regenerated solution dispensing monitoring device, the regenerated solution is tested and dispensed by a plurality of detectors in the regenerated solution dispensing monitoring device, the redox potential range of the regenerated solution is between 480 mv and 520 mv, the copper concentration is within the range of 30-60 g / L, and then the regenerated solution flows back into the etching production line to be used. The invention further discloses an acid etching solution recycling regeneration system for implementing the method.

The invention relates to a production method for selenium-containing collagen. The method adopts bones to make soup, turtles and chicken are contained in one pig stomach, pig skins and cow skins are contained in another pig stomach, the processed pig stomachs and fish are put together into a casserole filled with bone soup, and repetitive boiling, filtration, concentration, air drying, crushing and packaging are conducted to obtain the collagen product. The production technology of the invention is simple and unique, the expensive instruments and equipment are not required, the production period is short, the cost is very low, the produced product not only has the advantages and the application values of domestic and foreign similar products but also contains organic selenium, the contentof the organic selenium reaches 6.1mg / kg high and cannot be found in the existing literature, the collagen is a special collagen product, the application value and the development and popularization value of the collagen are very high, especially the selenium has great function on cancer fighting and thereby the development prospect is very high.

The invention relates to the technical field of poultry farming, in particular to a chicken breeding method utilizing tomatoes. Specifically, the chicken breeding method includes using mature tomato fruits as main foodstuff to feed broiler chicken. The main foodstuff, namely tomatoes, used in the chicken breeding method has extensive sources and is easy to get and low in cost; not only breeding cost of the broiler chicken is reduced, but also meat quality of the broiler chicken can be improved and is distinctive; and the commercial broiler chicken has good marketing prospect, high selling price and quite large development potentiality, and a feeder can make a profit.

The invention discloses a method for improving condition of Sophora buds from golden Sophora japonica. The method comprises the following steps: (1) water is added into an enzyme deactivating apparatus, alkali lye is added, and heating is carried out; (2) water and alkali lye are added into the enzyme deactivating apparatus every two hours in the heating process of the step (1), in order to guarantee alkali lye in a pot is kept at a certain concentration, heating is carried out till water is boiled, Sophora buds are added into the enzyme deactivating apparatus for carrying out enzyme deactivation, boiling state is kept and enzyme deactivation is carried out for 12-15 minutes, and the product is obtained. The method has obvious effects, processed Sophora buds from golden Sophora japonica have golden yellow color, good condition, and high price.

The invention relates to the technical field of livestock breeding, in particular to a green ecological breeding method for ducks fed with pale butterflybush flowers. The method comprises specific steps as follows: a duck-fish vertically-integrated breeding platform is constructed on water surface, and ducks fed with the pale butterflybush flowers are subjected to disease prevention and treatment and pesticide elimination by adding safe and originally ecological Chinese herbal medicines including the pale butterflybush flowers, Caesalpinia minax, liquorice, mints, lygodium spores, talcum powder and a Rabdosia rubescens decoction to pollution-free feedstuff. Due to rejection of any feed additives as well as antibiotics and veterinary drugs, the raised ducks fed with the pale butterflybush flowers are green products, duck meat has light pale butterflybush flower fragrance, and the quality is greatly improved.
