At present, it is so prominent in the development of the petrochemical industry in China，and it is accompanied by petrochemical wastewater, which has become a big problem need to solve urgently.Because petrochemical wastewater mainly contains benzene-compound, organic matter, high salt wastewater and oil sewage, etc. They are very damaging and highly contaminated. The composition and properties of the petrochemical wastewater were introduced firstly, the current situation of petrochemical wastewater treatment at home and abroad were reviewed in the study. Especially the development of petrochemical industry in sichuan was introduced. Based on the present situation and the existing problems, put forward some countermeasures and expect technique develop direction in the future.

With the extensive utilization of the bamboo industrialization, especially in developmental fields of bamboo-based panel, bamboo composite board, bamboo decoration, furniture manufacturing, which makes the application of bamboo have a broader prospect. However, the bamboo and its products in process of processing, transport and implementation often appear mildew, decay, moth-eaten, especially the mildew, it not only affects the appearance of bamboo and its products, but also creates damage conditions for other bacteria and insects. Therefore, bamboo timber preservation processing is the essential link for using bamboo industrialization. From the kinds of bamboo mould and its physiological characteristics, anti-mould technology and the types of mould inhibitor, this paper introduces the general situation at home and abroad and the existing problems and development trends of bamboo timber preservation, aiming to have a more comprehensive and systematic understanding of people for the bamboo mould and timber preservation, and to provide references for further study on the comprehensive anti-mould technology and preparation.

Combined with the research status of crop straws, and the comprehensive utilization of crop straws and the existing problems in Jilin Province, China. This paper proposes to crop straws to be used as the insulation materials of the precast concrete sandwich wall, which can’t only settle the problem of the lower utilization of crop straws, but also accelerate the development of the precast concrete structure in our country. Based on the research status of crop straws materials at home and abroad, the article summarizes the manufacture methods of crop straws as the insulation materials of precast concrete sandwich Wall. I hope that this article can provide valuable reference to speed up the comprehensive utilization of crop straws, and accelerate the process of building industrialization in Jilin province.

The purpose of this study is to determine learning difficulties, the factors that influence them, and what teaching strategies can overcome learning difficulties experienced by students in Al-Qur’an Hadith lessons at MI Muhammadiyah 12, Ngampel Village, Balong District, Ponorogo Regency. The results of this study are that learning difficulties experienced by students in Madrasah Ibtidaiyah Muhammadiyah 12 Ngampel Village namely students can not write, read, and memorize Al-Qur'an Hadith learning. Factors that influence it are internal factors, including students tired and lack of awareness of learning in themselves. While external factors, including family, the environment is less inters / good, and the lack of a habit to read the Qur'an when at home. To overcome these difficulties, it can be done by arranging strategies, methods, media, and techniques by existing problems.
