The present status about wastewater treatment at highway affiliated facilities of China including characteristics of wastewater and treatment technology, the effect of wastewater treatment were investigated. It was found that wastewater quantity was mainly depending on traffic volume entering the service area. Integrated process of wastewater treatment was the main technology used at highway affiliated facilities. 80.4% of the total devices discharge the water which can meet the “Integrated Wastewater Discharge Standard (8978-1996)”. About 69.6% of water was discharged into the road ditches, 22.2% was used for greening and flushing toilet. 3.9% of water evaporated naturally, 2.7% of water was discharged into the river, and only 1.6% was used for agricultural irrigation. The results provided scientific reference for the construction, improvement and management of wastewater treatment device at highway affiliated facilities by relevant departments in the future.

New Treatment

A set of new treatment facilities have been built to deal with the high-concentration of fluorine and ammonia-nitrogen (NH3-N) in wastewater generated from the preparation process of UO2 powder by ADU, whose concentration reaches up to 20g/L and 70g/L, respectively. Compared with various methods and summarized from vast experiences, a three-step technological process has been adopted. Firstly, fluorine is fixed by Ca(OH)2, and the product, CaF2, and other solids are filtered by centrifuge. And the teeny solids in the primary filtrate are precipitated by proper flocculants in pipe chute settling pond. Secondly, the treated wastewater with certain alkalinity is rectified by folded-plate rectifying tower. Meanwhile the ammonia is reused. Finally, adsorbed by specific adsorbent, the fluorine and NH3-N concentration of treated wastewater is further reduced. After numerous experiments and two-year running tests, the process control has been improved. Now, the wastewater treatment capability of the facility can reach 45m3/day. And the concentration of fluorine and NH3-N in the final wastewater is less than 10mg/L and 15mg/L, respectively, which can meet the state wastewater discharge standards. Besides, the concentration of the reused ammonia is raised from 5wt% to 25wt%, and the recovery can reach 99.3%.

The Way

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A

The Impact

Tsunami which was generated by the 2004 Aceh eartquake has beenhaunting our life. The building damage due to the tsunami could be seenthroughout Meulaboh Coastal Area. Appearing of the physical loss wasclose to our fault. It was caused by the use dan plan of the land withoutconsidering a tsunami disaster threat. Learning from that event, we haveconducted a research on the pattern of damage that caused by the 2004tsunami. Based on the analysis of tsunami hazard intensity and thepattern of building damage, it has been made a landuse planning whichbased on tsunami mitigation for Meulaboh. Tsunami mitigation-based ofMeulaboh landuse planning was made by intergrating some aspects, suchas tsunami protection using pandanus greenbelt, embankment along withhigh plants and also arranging the direction of roads and setting of building forming a rhombus-shaped. The rhombus-shaped of setting of the road and building would reduce the impact of tsunamic wave. It is expected that these all comprehensive landuse planning will minimize potential losses in the future .

Polluted Waters

Experience from advanced municipal wastewater treatment plants and recovery of polluted waters are described for the last ten years in Sweden. Except in municipalities with large recipients, the urban population is served by treatment plants with combined biological and chemical treatment. Most of these plants are post-precipitation plants. Several modified operational modes have been developed in order to improve the removal efficiencies of pollutants and to reduce the costs. Results are presented on the recovery of specially investigated lakes with a lowered supply of total phosphorus and organic matter.
