With the acceleration of the pace of urban construction, the city is changing with each passing day. At the same time, the reusable goods produced in people's life increase sharply, which puts forward higher requirements to the city waste recycling industry.  According to incomplete statistics, at present the city has more than 60 junkyard, each collection has a transit point to a dozen different Numbers, throughout the streets of dalian, Shahekou District is one of the largest local waste collection spot distribution density, is only 2 km from the west mountain reservoir to Ma Lanzi, there are more than 40 waste acquisition of transshipment point,  In the place with the largest density of waste acquisition in Dalian, there will be a transfer point every ten meters on average, and there will be a transfer point in less than one kilometer in the place with the smallest density.  Undeniably, the waste recycling industry has made contributions to the urban development of our city, but due to the lack of effective industry management and supervision mechanism, this industry is still in its infancy and exploration stage, no industrial chain has been formed, and some aspects even have hidden dangers and affect the normal life of citizens.  Specific problems exist in the following aspects:  1, the quality of employees is uneven, mixed.  At present, a large part of the waste recycling personnel in the city's transit points are migrant workers from remote and poor areas. It is difficult to thoroughly investigate the identity of people from all parts of the country, among which there are many illegal criminals with previous convictions, which has hidden dangers in social security.   2, waste recycling stations (points) become a new source of urban pollution.  Most waste recycling stations lack environmental awareness. They reorganize the acquired waste products and knock them in the process of disassembly to create noise pollution. They burn electric wires and cables and disassemble home appliances such as refrigerators and air conditioners to create air pollution.  3. Irreasonable points have seriously interfered with the normal life of surrounding residents.  There are many waste collection stations in residential areas, or even downstairs.  The acquisition stations piled up the purchased waste materials at will, without paying attention to environmental hygiene. Sewage flowed everywhere in summer and waste flew everywhere in winter, causing difficult roads and bad smell, which seriously affected the normal life and work of the surrounding citizens.   4. Scattering stations make it difficult to centralize management, which becomes a hidden danger to social security and fire safety.  The decentralized operation of waste recycling stations makes it difficult for relevant departments to centralize management.  Waste recycling stations (points) are mostly set in residential areas, and the collected wastes are mostly flammable items, which are stacked and stored in the gate for a long time. At the same time, and the employees are basically living and eating in the gate, so there are great fire safety risks.  At the same time, practitioners of weak legal awareness, illegal acquisition of railway, power supply, communications, urban public facilities and other special equipment, some are stolen stolen goods, so that the waste recycling station into the channel of stolen goods, the formation of a serious social security hidden danger.   5. The waste transport vehicles jam the traffic, and the goods are leaked and overloaded, resulting in traffic safety risks.  Most of the waste recycling stations occupy limited space, and only when the waste is stored in a certain amount can they be arranged for outward transport. Because the vehicles for the transport of waste are generally large vehicles, the loading and unloading of waste occupy most of the road, which seriously affects the normal traffic of vehicles.  For example, a waste recycling station in front of No. 7 of Dalian Locomotive & Rolling stock Company on Xiguan Street, when loading waste, transport vehicles almost occupy half of the road, causing a serious traffic jam of more than 200 meters from Xiguan Street to the intersection of Xishan Street and Xi 'an South Road.  At the same time, the transportation of waste vehicles over the limit, loading and binding is not fast, items fall off, hanging collision overhead wires and other problems are easy to occur, buried a hidden danger for traffic accidents.
