Abstract: A system for purifying rainfall runoff including a bar screen; a collection and diversion device; a filter channel; a grass ditch; and a water storage tank. The bar screen is disposed around the collection and diversion device for preliminarily filtering the road rainfall runoff. The collection and diversion device collects the road rainfall runoff and diverts early rainfall runoff to the filter channel, after the filter channel is full, later rainfall runoff is directly diverted to the grass ditch through open channels. The grass ditch includes a percolation bed capable of filtering the early and later rainfall runoff. The water storage tank is connected to the grass ditch via a guiding pipe, to receive the rainfall runoff effusing out of the grass ditch. Part of the rainfall runoff received by the water storage is transported to the percolation bed by a return conduit.

Abstract: Disclosed is a process for preparing 5-aminosalicylic acid by gas phase catalytic carboxylation, characterized in that carbon dioxide is introduced into a system of p-acetaminophenol and a basic compound at a temperature of 150° C.˜220° C. and a pressure of 0.5˜5.0 MPa in the presence of a catalyst, so as to carry out a gas phase catalytic carboxylation reaction to form a 5-aminosalicylate, and the crude product 5-aminosalicylate is separated, and then acidified to prepare 5-aminosalicylic acid (5-ASA). Since the gas phase catalytic reaction replaces a solid phase thermo-chemical reaction, the reaction is significantly improved in terms of the process flow, reaction conditions, product quality and energy consumption. In addition, the reaction has a short reaction time, good selectivity, high yield and no formation of wastes during the reaction, and is suitable for industrial production.
