The invention discloses a methyl gluceth-containing glyphosate aqua synergist aid. The synergist aid is a methyl gluceth-containing special surfactant composition for glyphosate aqua, and contains an effective component of methyl gluceth. The glyphosate aqua synergist aid is suitable for various salt aquae of glyphosate, has the advantages of excellent moisture retention property, substantial synergistic effect on preparations, strong biodegradability and environmental protection facilitation, and meets sustainable development requirements of the glyphosate preparations.

The invention discloses a process for extracting commercial grease by using tanning waste liquor containing grease, which comprising the following steps: (1) filtering the grease by grids; (2) adding sulphric acid into a concentrating purifying and layering tank; (3) collecting white supernatant liquid containing grease at the upper layer; (4) dripping water in a drying bed; (5) sending the grease into a pan to steam water; and (6) obtaining the commercial grease by the pressing of a presser. The process ensures that the waste liquor containing grease is directly prepared into the commercial grease during the tanning after being pretreated in the prior period, has wide purpose, realizes the purposes of saving energy and reducing emission, turning the harmful into the beneficial and changing waste into valuable, has simple process, investment saving and low operation cost, reduces COD, BOD and SS in the waste liquor by respectively 90 percent, 95 percent and 98 percent, greatly lowers the difficulty of the tail treatment of the tanning waste liquor and settles the solid basis for the sustainable development in the tanning industry. The recovery cost of every ton of grease is within 1400 RMB by the method.

The invention discloses a solar photo-thermal system and ground source heat pump system coupled composite energy supply system. The composite energy supply system comprises a solar thermal collector,a lithium bromide absorption type refrigerating unit, a heat exchanger, a heat storage device and a ground source heat pump. According to the composite energy supply system, solar energy and geothermal energy are coupled and integrated, so that complementation of advantages of the two renewable energy sources is achieved, and the energy utilization rate of the system is further improve; and compared with an existing split type air conditioner energy supply mode of rural residence buildings in Huna Province, the renewable energy utilization efficiency is greatly improved, and furthermore, a newidea for sustainable development of the environment is provided, so that great practical significance is achieved.

The invention discloses a solar monitoring system, which comprises an upright column; a first connecting rod arranged on one side of the top end of the upright column, wherein a solar generator is arranged on the top of a first supporting rod; a second connecting rod arranged on the other side of the top end of the upright column, wherein a supporting disk is arranged on the top of a second supporting rod, a protection shell is arranged on the top of the supporting disk, and a monitoring part is arranged in the protection shell; and an alarm part and a monitoring box arranged in the middle ofthe upright column. According to the solar monitoring system, the solar generator can convert solar energy into electric energy so as to monitor continuously; the use of solar energy avoids the layingof a grid and greatly reduces the cost of monitoring; the solar energy is clean energy, and meets the sustainable development; by using solar energy to supply electricity independently, the thoroughwireless transmission is realized; and the system is flexible in assembly, small in size, convenient to install, independent of each upright column, and capable of improving safety.

The invention discloses a rural residential area regulation and grading method based on space suitability and internal characteristics. The method comprises the steps of collecting rural residential areas and peasant household basic data; constructing a rural residential point renovation space suitability internal characteristic grading regulation and control evaluation index system; constructinga regulation space suitability intrinsic characteristic grading regulation and control evaluation model; calculating rural residential area regulation and control grading by using a GIS; and determining and outputting a rural residential area regulation and control grading result. Based on GIS technology, the invention quantitatively analyzes the willingness of farmers, individual differences of rural residential areas and spatial suitability characteristics, constructs a rural residential area grading regulation model, comprehensively considers the spatial suitability of the rural residentialareas and the internal characteristics of the rural residential areas, enables the regulation grading to be specific to the residential areas, achieves the precise grading of the rural residential area regulation, and improves the regulation efficiency. The purpose of sustainable development of rural space is achieved.
