The direct discharge of domestic sewage into the river is not in compliance

"Domestic sewage discharge is the most important cause of urban river pollution." The relevant person in charge of the Municipal Water Resources Bureau said. Ms. Mao, who lives near Yantietang, is also deeply touched by this. The environment near Yantietang is good, but to be honest, the water quality in Yantietang is not good in the past two years, especially in summer, and the river water easily stinks. It is understood that some restaurants and renters along the Yantietang River directly discharge sewage into Yantietang, causing the river to stink.

in order to comprehensively sort out and improve the municipal drainage pipe network system, find out the pollution discharge situation, speed up the pace of sewage interception and acceptance, strengthen drainage management, and rectify the disorder of misconnection, our city plans to build the drainage standard area in the main urban area in two years from the beginning of September 2114, striving to control sewage discharge from the source, standardize drainage behavior, and effectively improve the urban water environment.

the municipal water resources bureau divides the old city and the new city into 14 and 19 drainage areas with the main roads and rivers as the boundaries, and carries out the construction of drainage standard areas one by one. Drainage census personnel will investigate the drainage status of each drainage area, formulate rectification plans according to the investigation, and implement the rectification.

this year, the old city plans to complete the general survey of 8 districts and the rectification of 5 districts, and the new district plans to complete the general survey of 12 districts and the rectification of 6 districts. At present, the general survey of four districts in the old city has been completed, and 717 drainage households, 289 buildings and 29.92 kilometers of pipe network have been investigated. In the new area, there are 539 drainage merchants, 318 buildings and a pipe network of 15.61 kilometers.

In the general drainage survey, the census personnel found that the rainwater and sewage were not separated, and the residents were connected by mistake and disorderly, which became the difficulties of governance.

The census personnel explained that according to the relevant laws and regulations, food and beverage outlets need to be equipped with pretreatment facilities such as grease trap, grille well and residue filter pool, and the oil fume should not be discharged into drainage facilities. The person responsible for cleaning oil and waste should be appointed at least once a week to prevent a large amount of oil pollution from accumulating and ensure the smooth pipe network. However, many small restaurants did not have these facilities at all in the census, and even large catering enterprises did not fully meet the discharge standards.

it is also illegal for residents to discharge sewage into rainwater pipes or directly into rivers by mistake. In the investigation, the reporter found that there are many residents in the community who directly discharge the washing wastewater and oily wastewater from the kitchen into the rainwater pipeline after moving the washing machine or kitchen to the balcony. There are also some drainage households who lay sewage pipes on the external walls themselves due to decoration or sewer blockage, but the pipes are not connected to the municipal sewage pipes. These sewage enter the river, which has a great impact on the water environment of the river.

in addition, the drainage system of the old urban areas that have not been reconstructed still adopts the combined system, some of which flow to the sewage treatment plant through the municipal sewage pipe network, and some of which are directly discharged into the river. In some residential areas, rainwater risers are directly connected to sewage pipes, and rainwater on the roof flows to sewage treatment plants, which increases the load of sewage treatment plants.

"These problems will be the focus of future rectification." The relevant person in charge of the Water Affairs Department of the Municipal Water Resources Bureau introduced that after the investigation, systematic rectification will be carried out, and some old communities will be further transformed, and sewage will be intercepted as much as possible; Require illegal food and beverage outlets to make rectification.
