11. Wastewater
Classification
According to the chemical properties of the main pollutants contained in industrial wastewater, it is divided into: inorganic wastewater mainly containing pollutants, organic wastewater mainly containing organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metals. These are waterwastewater, wastewater containing radioactive substances and cooling water which is only contaminated by heat. For example, electroplating wastewater and mineral processing process wastewater are inorganic wastewater, and food or petroleum processing process wastewater are organic wastewater.
According to the products and processing objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, tanning wastewater, pesticide wastewater, metallurgical wastewater, wastewater oil refining waste, etc.
According to the main components of pollutants contained in wastewater, it can be divided into acidic wastewater, alkaline wastewater, phenol-containing wastewater, chromium-containing wastewater, organophosphorus-containing wastewater and radioactive wastewater, etc.< /p>
Recyclable wasterefer to waste that has a high recycling value and can enter waste recycling streams. Mainly including: paper (newspapers, magazines, cartons and other uncontaminated paper products, etc.), metal, glass (glass bottles and jars, flat glass and other glass products), plastic products Except for plastic bags, rubber and rubber products, milk boxes and other Tetra Pak packaging, beverage bottles, etc.
Non-recyclable waste includes kitchen waste, hazardous waste and other waste. However, as kitchen waste should not be placed in roadside bins, non-recyclable waste in the bins is hazardous waste and other waste.
Hazardous waste refers to waste containing toxic and harmful chemicals, such as: batteries, used lamps and bulbs, medicines, etc.used, expired daily cosmetics, hair dyes, pesticide containers, herbicide containers, discarded mercury thermometers, discarded small waste. household appliances, discarded printer ink cartridges, toner cartridges, etc.
Other waste is a general term for all waste, except recyclable waste, hazardous waste and kitchen waste, including: contaminated and non-renewable paper, contaminated glass or other non-recyclable, plastic bags and other contaminated waste. plastic products, used clothing and other textiles, used ceramics, shells, cigarette butts, dust, etc.

Waste specifications
Waste specifications waste to the extent that it does not meet the original specifications or technical standards, it may be classified as waste rrepairable or non-repairable waste. Repairable waste means that the waste can be used after being repaired.
And the cost of repair is economically unreasonable; irreparable waste means that the waste cannot be repaired, or the cost of repair is not economically viable.
Scrap losses include scrap losses after the cost of irreparable scraps less the recyclable residual value of scraps and the repair costs of repairable scraps.
All losses incurred on scrap products discovered after sale, including freight charges paid on return of scrap products, etc., should be treated as administrative costs and are not included in the loss of scrap products.
The loss of repairable scrap products is generally the same as the cost of qualified products. Firstly, the “loss of waste” account is debited and thes accounts concerned are credited according to the distribution table of material costs, salaries. expenses, auxiliary production expenses, manufacturing expenses, etc.
Accounting
In order to calculate the loss of waste products during the production process, it can be defined under the “Basic Production” account.Organize the accounting of the detailed account “waste losses.” In the debit, the production costs of irreparable scrap metal and the repair costs of repairable scrap metal are recorded.
The creditor records the value of the recycled scrap metal which must be deducted from the cost of the scrap metal. The difference between the above-mentioned contents of the debit and the creditors of this account constitutes the total net waste loss of the business.
The share corresponding to the offender will be transferred from his credit to the debit of the “Other receivables” account, and compensation will be requested as soon as possible for the lossesnet remaining waste; be attributed to the same type carried out during the current period. The cost of the product is included in the “loss of waste” item.
That is, the credit of the account “Basic Production - Scrap Loss” is transferred to the debit of the account “Basic Production - ×× Products” After the transfer, the account “ Basic production - Loss of scrap metal. "The account must not have a final balance.
