Seal of Assessment Reishiiiso Bay will be the main accessing area , which receive6 the sewage from Malan River,It locat at 1210 20 ' -40 ' east longtitude and 38* 50' -53' latitude.The entry of the bay is 16km wide and 4.8km away from the top of the bay. There is about 36km2of water area within the bay.In addition, the land part of tie sewage tretment plant, which stretch eastern to Nadating,that is the entry of Malan River,western to Malan River Bridge,northern to the foot of Baizi Mountain and southern to Sports Center with Land area of 5km2 . The atmosphere and sea area within this region will be regarded as what affected by sewage, thus, the environmental impact assessment limited within this area will meet the requirment. 1.6. Target of Environmental Project The project of Malan River Sewage Treatment is a environmental project item in Dalian, which will be loaned ny World Bank to completely solve the pollutant problems of Malan River. Chapter 2.Survey of project 2.1. Backgrounad And Importance of The Project Malan River is mAin flood- discharging and sewage -discharging Channel in south-west of Dalian with length of 14km and river basin area of 96 km'.Downstream of the river are main industrial area and residential area of western Dalian with over 80 of main sewage - discharging units. The sewage is discharged into vhe river through 39 pollutant -discharging points..Meanwhile,Malan River also recives the living sewage from about 30000D residents and overland runoff along the river.Total quantity of sewage reaches to 50000oma, which flow into Heishijiao Bay throuth the entry of Malan River. Along Beishijiao Bay is the famous scenic spot of Dalian. Its sea area are famous sea bathing and breeding farm of rare marine organisms.Meanwhile, it also acts one of the main sewage-receiveing area.From the coastal line of Lingshui Bridge to Fujiazhuang distribute main sewage - discharging points, part of sewage have been intercepted to the entery of 2 recvcled oaper ertdog% and etuimnrn,  Malan River and its surrounding water area have been heavily polluted.Therefore,improTment of the water quality whithin Beishijiao Bay has become a imDortant environmental engineering problem waited to solve. To solve the pollutant problem of NEalan River,Dalitn City Government has built some projects in separate periods every year, is 1984.4km intercepting pipe in the western line of Malan River was built aLd in 1989 9km intercepting and sewage pumD station was built.1eanwhile, in 1990 Environmental Protection Institute of National Ocean Breau Compiled the. 'Study cc Feasibility of Dalian Heishijiao Bay Sewage- Sea -Discharging Projectand in February, 1992 Dalian Gardens Design institute finished 'the stuty on Feasibility of of Dalian Malan River Sewage Sea-Discharging Project-.From above,jRe can see,many prephase jobs of the project have been prepared, which will provide a good basis for further studys. leanwhile,1alian is also a city severely siort of fresh water resource.The mean person-owned amount is 703m
