This invention provides the application of polyferric sulfate in improving plant salt stress resistance and / or improving saline-alkali land, belonging to the field of agricultural technology. The polyferric sulfate application provided by this invention can effectively improve the germination ability of plant seeds under salt stress, effectively enhance the activity of plant antioxidant systems and photosynthetic efficiency, thereby effectively improving the survival rate and growth performance of plants under salt stress. Simultaneously, polyferric sulfate can effectively reduce the EC value of saline-alkali soil, thereby effectively improving the germination rate of plant seeds in saline-alkali land and effectively improving saline-alkali land. This invention is simple to operate, low in cost, and environmentally friendly, suitable for enhancing the salt and alkali tolerance of plants, and has broad application prospects.

The invention relates to the technical field of detergent wastewater treatment, in particular to a method for treating detergent wastewater by utilizing foundry waste sand regeneration waste. According to the method, waste generated after foundry waste sand regeneration is taken as a basis, and the detergent wastewater is pretreated by establishing a'Fenton oxidation + flocculation precipitation 'dual system, so that the problem of waste discharge of a novel regeneration process is solved, efficient degradation of COD (Chemical Oxygen Demand) content in the detergent wastewater is also realized, and the purposes of'waste recycling' and'treating waste with waste 'are achieved.

The invention discloses a flocculating agent for machine cleaning wastewater of a pesticide missible oil preparation and application of the flocculating agent. The flocculating agent is prepared from the following components in parts by weight: 50-60 parts of an inorganic flocculating agent, 35-45 parts of an organic flocculating agent, 8-12 parts of a demulsification aid and 4-6 parts of a pH regulator. The flocculant disclosed by the invention is good in demulsification effect, high in COD removal rate, high in treatment efficiency, strong in floc stability, economical in cost and wide in wastewater adaptability, and solves the problems of poor demulsification effect, low COD removal rate, large flocculant dosage and the like when an existing flocculant is used for treating pesticide missible oil preparation cleaning wastewater.
